Arabic Conjunct-sensitive Agreement and Primitive Operations

Abstract: In some Arabic dialects pre-verbal coordinated subjects cause plural agreement

on the verb while post-verbal ones cause either plural agreement or singular agreement.

This paradigm has been addressed by Aoun, Benmamoun, and Sportiche (1994, 1999)

and Munn (1999) to varying degrees of success. This reply offers an improvement on the

previous analyses by utilizing the concept of decomposed merge (Hornstein 2009)

whereby merge is reanalyzed as two suboperations. Previously unexplained cases that

flaunt the paradigm are explained here by a decomposition of the extension condition

(Chomsky 1995) and a derivational account of pronoun binding across coordination.

Introduction

There is a long-standing dispute over Arabic conjunct-sensitive agreement (ACSA). The

two approaches discussed here capture large swaths of empirical landscape, yet some

data points still evade explanation. In this reply I offer an account that handles the basic

facts and captures recalcitrant cases. Further, this paper argues for the decomposition of

Merge into two suboperations and pares down the extension condition of Chomsky 1995.

The approach offered here is that coordinated subjects can optionally Label when

Merged together. When Labeling occurs, plural agreement is effected. When Labeling

does not occur, only one conjunct can be agreed with, effecting singular agreement. Only

Labeled objects function as constituents (following Hornstein 2009) and as such only

they can move to pre-verbal positions. This correctly predicts that pre-verbal coordinated

subject must effect plural agreement whereas post-verbal ones can effect either plural or

singular agreement.

In section 1 I discuss the bi-clausal approach proposed by Aoun, Benmamoun,

and Sportiche (1994, 1999) as well as the mono-clausal approach of Munn (1999). In

section 2 I rehearse the motivation behind the decomposition of Merge and extend this

argumentation to coordination following Larson 2010. In section 3 I offer a decomposed

Merge analysis for the basic paradigm and show that it covers more empirical ground

than the previous approaches. Section 4 addresses the recalcitrant data that neither

previous approach can account for. These data are coordinated subjects in which one of

the conjuncts is a quantified noun phrase and the other has a bound pronoun. The new

account captures these via the decomposition of Merge coupled with theories of Arabic

quantified NPs from Benmamoun (1999) and Mohammad (1988). Further, I argue that

quantifier-variable binding across coordination is subject to derivational constraints.

1 Background

ACSA sentences are exemplified in (1) below from Aoun, Benmamoun, and Sportiche

1999.1 This sentence has two coordinated subjects yet only singular agreement appears

on the verb. This contrasts with (2) in which a normal plural noun effects plural

agreement on the verb from Aoun, Benmamoun, and Sportiche 1994.2

Page 3: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

3

(1) ža ʕomar w karim (MA)

came.SG Omar and Karim

‘Omar and Karim came.’

(2) wəәqfu ləә-wlad (MA)

stood.PL the-children

‘The children stood up.’

1.1 Bi-clausal Analysis Advantages

The bi-clausal account derives (1) as follows. The sentence appears mono-clausal, but

this is a PF deception. Under conjunction reduction, sentence (3) can be reduced to (1).

(3) ža ʕomar w ža karim (MA)

came.SG Omar and came.SG Karim

‘Omar came and Karim came.’

In addition to (1), sentences like (4) are also possible and clearly could not have

been derived via conjunction reduction, as Aoun, Benmamoun, and Sportiche admit.

(4) žaw marwan w karim (MA)

came.PL Marwan and Karim

‘Marwan and Karim came.’

Page 4: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

According to them, we have herein a suitable test of their approach. Sentences

like (4) where the subject is syntactically plural at every stage of the derivation should be

acceptable with elements that require plural subjects. Sentences like (1) in which the

subject is only superficially plural should not be acceptable under the same conditions.

Reciprocals require plural subjects and the prediction is borne out as shown in (5) below.

(5) a. gəәlsu ʕomar w karim ħda bəәʕḍhum

sat.PL Omar and Karim near each.other

‘Omar and Karim sat near each other.’

b. *gləәs ʕomar w karim ħda bəәʕḍhum

sat.SG Omar and Karim near each.other

1.2 Disadvantages

The Aoun, Benmamoun, and Sportiche analysis is relatively unconstrained and risks

overgeneration. It indeed seems to make false predictions of acceptability as seen in (6).

(6) karim w marwan mšaw/*mša (MA)

Karim and Marwan left.PL/left.SG

‘Karim and Marwan left.’

The sentence above shows that, unlike post-verbal coordinated subjects, pre-

verbal ones generally obligatorily show plural agreement. Aoun, Benmamoun, and

Page 5: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

5

Sportiche (1999:678) admit that they have “no explanation for why first conjunct

agreement is not systematically possible in the SV order.”

Additionally unexplained in their account is the fact that subject-initial ACSA is

occasionally acceptable, albeit in a severely constrained set of circumstances. Shown

below, when the first conjunct is a quantified noun phrase and the second conjunct

contains a pronoun bound by that first conjunct, singular agreement is possible.3

(7) kull wəәld w bba-h mša (MA)

every boy and father-his left.SG

‘Every boy and his father left.’

The extent to which Aoun, Benmamoun, and Sportiche can explain (7), they

cannot explain (6), and vice versa.

1.3 Mono-clausal Analysis Advantages

The mono-clausal analysis of Munn 1999 accounts for the paradigm by distinguishing

semantic from syntactic plurality. Doing so is fairly straightforward. For example, the

English noun group effects singular agreement but, being necessarily composed of

multiple entities, is semantically plural. Compare this with the English noun scissors

which spurs plural agreement yet is semantically singular. This distinction can be seen in

the examples below modified from Munn's.

Page 6: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

6

(8) a. The group was wearing different hats.

b. The men were wearing different hats.

c. *The man was wearing a different hat.

d. *The scissors were different colors.

With the relevant, non-discourse linked interpretation of different we clearly see a

dissociation of semantic and syntactic plurality. The acceptability of the sentences hinges

not upon syntactic plurality (see the differing agreement on the auxiliaries) but upon

whether the subjects are semantically multiple.

Munn shows that that the reverse is also the case. There are elements that require

syntactic plurality, independent of semantic plurality. Seen in (9), anaphors must agree

with their controllers in their syntactic plurality. For example, though the group is

semantically plural, that is insufficient to license the plural reflexive

(9) a. *The group is keeping themselves in shape.

b. The group is keeping itself in shape.

c. The scissors are by themselves on the table.

d. *The scissors are by itself on the table.

Munn argues that the coordinated subjects in Arabic are like the group above:

semantically plural, syntactically singular. The distinction explains the unacceptability of

(5b). In Arabic ‘each other’ requires syntactic plurality; semantic plurality is insufficient.

Page 7: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

Munn’s analysis argues for the possibility of agreement to be mediated through

what he dubs Exceptional Government: the relation between a head and its complement’s

specifier (akin to the notion of agreement under government of Mohammad 1988,

Benmamoun 1992, and Bahloul and Harbert 1993). Assuming agreement is mediated

through this relation and assuming the analysis of coordination as adjunction of Munn

1993 we are able to derive sentences in which post-verbal coordinated subjects cause

singular agreement. The sentence in (1) would have a (simplified) structure like (10).

(10) [TP žai [VP [DP [DP ʕomar] [&P w karim ] ] ti ] ] (MA)

came.SG Omar and Karim

‘Omar and Karim came.’

Pre-verbal subjects are different. Here agreement is not mediated by exceptional

governance but by spec-head agreement. That is, instead of a structure like above the

sentence in (6) has the structure like that in (11).

(11) [TP [DP [DP karim] [&P w marwan ] ] mšaw [VP …] ] (MA)

Karim and Marwan left.PL

‘Karim and Marwan left.’

Munn suggests that this configuration might straightforwardly entail plural

agreement. Since both the first conjunct DP and the BP are in the specifier position then

Page 8: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

8

this might be what requires plural agreement in these cases. These differential agreement

mechanisms account for the different agreement patterns. Munn’s analysis predicts that

pre-verbal subjects effect plural agreement and post-verbal ones singular agreement.

1.4 Disadvantages

The mono-clausal analysis cannot readily explain the fact that plural agreement is an

option with post-verbal subjects. Munn admits as much as suggests that this option may

be due to some prescriptive overgeneralization. Ignoring the conceptual distaste that such

an idea stirs, the extent to which a more formalized explanation can be posited, that

explanation should be preferred for at least being more easily falsified.

A more interesting failing of this account noted by Aoun, Benmamoun, and

Sportiche 1999 concerns the collective or distributive readings of coordinated subjects.

They note that with coordination of proper names, there is an ambiguity. Example (12)

can mean that Alya and Marwaan read a single story (a collective reading). It can also

mean that they each read a story for a total of two stories read (a distributive reading).4

(12)

Yet, when a quantified noun phrase is coordinated with a noun phrase containing

a bound pronoun, the sentences are unambiguous. They only allow a collective reading.

Benmamoun, and Sportiche (1999) note the following distinction. With coordination of

noun phrases, there is an ambiguity. The sentence (16) can be understood as meaning that

Alya and Marwaan read a single story (a collective reading) and it can also mean that

they each separately read a story for a total of two stories read (a distributive reading).4

(16) !!ryo "alya w marwaan !!##a (LA)

read.PL Alya and Marwaan story

‘Alya and Marwaan read a story.’

However, when a quantified noun phrase is coordinated with a noun phrase

containing a bound pronoun, the sentences are unambiguous. They can only have the

collective reading. That is to say, the sentence can only have the reading in which each

woman-child pair read one story, not two.

(17) !!ryo k!ll mara w !!bna !!##a (LA)

‘Every woman and her child read a story.’

Page 9: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

9

The sentence only has a reading in which each woman-child pair read one story, not two.

In the Munn’s analysis, the sentences (12) and (13) are structurally identical in the

relevant respects. As such, we do not expect them to differ in their interpretations.

(13)

1.5 Summary

The two accounts here cover a great deal of the data. But there are two central failings

that they succumb to. Neither account handles the full range of agreement patterns. The

Aoun, Benmamoun, and Sportiche account handles the post-verbal agreement facts fine,

but fails to predict the lack of variability in agreement with pre-verbal subjects. Munn’s

account captures the post-verbal subject's singular agreement and the invariability of the

agreement with pre-verbal subjects, but fails to predict variability with post-verbal ones.

This is shown below. Checkmarks indicate that the analysis can handle the relevant data.

1.5. Summary. The two accounts presented here cover a great deal of the empirical

ground. But there are two central failings that they succumb to. Neither account

handles the full range of agreement patterns gracefully. The bi-clausal account can

handle the post-verbal agreement facts fine, but it fails to predict the lack of vari-

ability in agreement with pre-verbal subjects. The mono-clausal account captures

the post-verbal subject’s singular agreement and the invariability of the agreement

with pre-verbal subjects, but it fails to predict the variability in the post-verbal facts.

This is displayed visually in the table below. Checkmarks indicate that the analy-

sis can handle the relevant data. For example, the bi-clausal analysis can handle

the post-verbal plural agreement facts, but the lack of variability in the pre-verbal

agreement facts.

Furthermore, both analyses fail in the face of data involving quantified noun phrases

cause singular agreement in a pre-verbal position. The mono-clause analysis cannot

predict the di!erences in ambiguousness between the quantified and non-quantified

noun phrases.

In what follows I will present an account that deal with the entire scope of the

phenomena as presented in the table in a unified fashion. And in conjunction with10

singular agreement in a pre-verbal position. Munn’s analysis cannot predict the

differences in ambiguity between the quantified and non-quantified noun phrases. In what

follows I present a unified account that deals with the entire scope of the phenomena.

2 Decomposed Merge

Here I revisit the motivation for decomposing Merge (Chomsky 1995). For the sake of

space this is but a sketch of the argumentation in Hornstein 2009. The main motivation

comes from the differential targeting of adjuncts. Under Bare Phrase Structure (BPS)

(Chomsky 1995), capturing adjuncts becomes difficult and the decomposition of Merge is

an attempt to correct this. Coordination is taken to be adjunction and should be amenable

to a decomposed Merge account. I pursue this here with the aim of applying to it ACSA.

2.1 Bare Phrase Theory

Under BPS, categorial labels are no long extrinsic entities with rigid positions along a

derived skeleton. There had existed prior such things as X0, X', and XP and they had

fixed positions, unchanged throughout the derivation (Jackendoff 1977). Now they are

mere clarificational substitutes for lexical items. Instead of (15) we now have (16).

(15) (16)

previously established accounts of quantifiers in Arabic, I will use my unified analysis

to account for the recalcitrant data concerning quantifiers.

This requires a little background first.

2. Decomposed Merge

2.1. Bare Phrase Theory. With advent of Bare Phrase Structure (BPS) (Chom-

sky, 1995), categorical labels were no long extrinsic entities with rigid positions along

the derived skeleton. Before BPS there existed in the theory such things as X!, X’,

and XP and they had fixed positions and went unchanged throughout the derivation

(Jackendo!, 1977). Now, although for practical purposes the above terms are still

readily used, they are mere clarificational substitutes for lexical items. That is, in

BPS instead of (19) we have (20).

What were non-lexical entities are now lexical ones. In addition to this, the notions

What were non-lexical entities are now lexical ones. In addition to this, the

notions of minimal, intermediate, and maximal projection have been relativized. In (15)

the X' level was, and always will be, an intermediate projection. In (16), the middle saw

is an intermediate projection, but this was not always so. Before Ivan was Merged, saw

was a maximal projection. It was the highest projection of saw and as such, maximal.

Given that that these terms are now relational, it becomes clear that there can only

be one maximal projection of a given head. This causes a problem with adjunction.

2.2 Adjunction

Hornstein (2009) presents the following conundrum. There can only be one maximal

projection per head. Prior to BPS, this was not the case and in particular adjunction

extended the tree but did not change the bar level information. As seen in (17), an adjunct

could adjoin to a VP and the Label dominating that would in turn be another VP. This

was advantageous. Certain operations only work on maximal projections, say VP-ellipsis.

In the above structure VP-ellipsis can operate on the inner (19a) or outer (19b) VP.

(17) Iris [VP [VP felt good] on Sunday]

(18) Iris felt good on Sunday...

(19) a. ...and Ivan did on Saturday.

Page 12: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

12

But with BPS, we can no longer capture these facts. What is considered a

maximal projection is now relative and not inherent to any node. As such, the structure in

(17) only has one maximal projection, the outer VP. We no longer have a means of

operating on the VP to the exclusion of the adjunct.5

2.2.1 Decomposed Merge

To solve this dilemma, Hornstein proposes a decomposition of the Merge operation.6

Merge, as construed in Chomsky 1995 takes two syntactic elements and combines them,

projecting one of them as the Label of said combination (20).

(20) Merge(X,Y) [XP X YP]

Hornstein instead posits that the above operation be split into two: Concatenate

(21) and Label (22). Concatenate takes two atomic syntactic units and combines them

into a complex of atomic units. Label makes said complex atomic itself by choosing one

of the elements of the Concatenation operation to serve as the Label of complex.

(21) Concatenate(X,Y) [XP YP]

(22) Label(X,[XP YP]) [XP X YP]

two maximal projections (24).

According to the theory, normally both of these operations are carried out, but

with adjunction this is not the case. Adjuncts, not being necessary to the derivation, do

not necessarily have to undergo Label.

This decomposition allows for an elegant account of the differential behavior of

adverbial modification. When an adverb Concatenates with a verb and does not project

(23), the verb+adverb complex is, in Hornstein's words, “invisible” to the rest of the

structure.7 So when an operation like VP-deletion targets a VP with a Concatenated

adverb, the VP deletes leaving the adverb behind (24).

As shown above, adjunction can be wedded to BPS in an elegant fashion. But

more than just adverbs have been argued to be adjuncts. For instance, Munn (1993)

argues that coordination is also an adjunction structure (31).

adverbial modification. When an adverb Concatenates with a verb and does not

project (27), the verb+adverb complex is, in Hornstein’s words, “invisible" to the

rest of the structure.9 So when an operation like VP-deletion targets a VP with a

Concatenated adverb, the VP deletes leaving the adverb behind (28).

VPrun

(28) Ivan ran slowly and Ivy did quickly.

When an adverb is both Concatenated and Labeled into the structure (29), VP-

deletion applies to the adverb as well (30).

As shown above, adjunction can be wedded to BPS in an elegant fashion. But

more than just adverbs have been argued to be adjuncts. For instance, Munn (1993)

argues that coordination is also an adjunction structure (31).

(27)

Larson (2010) argues for similar tack with respect to coordination. In (28) below,

it is possible to target both the topmost VP for deletion and also a lower one. And in (29),

it seems that the anaphor can be bound by either to topmost DP or by a lower one.

c. … while Ivy [did] and read a book

(29) a. I showed [DP the man] and the woman to [himself] and herself in the pond.

b. Ivan showed [DP the man and the woman] to [themselves] in the pond.

If allowed only one XP per projection, there must be some other means of

capturing these facts. The decomposition of Merge seems to be sufficient. We simply

have structural ambiguity with coordination, just like with traditional adjunction. That is,

for example (29a), the structure of the coordination is like in (30). For (29b), the structure

is like (31). In the following section I extend this analysis to Arabic coordinated subjects

2.4. Extension to Coordination. Larson (2010) argues that a similar Hornsteinian

tack must be taken with respect to coordination. The structural ambiguity that

Hornstein posits is also found in coordination. In (32) below, it is possible to target

both the topmost VP for deletion and also a lower one. And in (33), it seems that

the anaphor can be bound by either to topmost DP or by a lower one.

(32) a. Ivan [V P [V P ate an apple] and wrote a letter] in the park

b. . . . while Ivy [did so] in the library

c. . . . while Ivy [did so] and read a book

(33) a. Ivan showed [DP the man] and the woman to [himself] and herself in the

mirror

b. Ivan showed [DP the man and the woman] to [themselves] in the mirror

If we only have one XP per projection, as in BPS, then we need some other way to

get these facts. The decomposition of merge discussed in the previous section seems

to fit the bill. We simply have structural ambiguity with coordination, just like with

traditional adjunction. That is, for example (35a), the structure of the coordination

is like in (34).

with plural agreement (33). In this section I show how my approach accounts for these.

Given the decomposition of Merge and its relation to adjuncts, we now have two ways to

compose coordinated subjects. In this section we will concern ourselves with coordinated

elements in which only the Concatenate operation has applied (34).

(34)

Say that the above structure was the coordination of Omar and Karim from (33)

with singular agreement. In this structure Omar is singular and as such should precipitate

singular agreement on any verb it serves as subject for. As a DP, Omar is also targetable

as an external argument. The complex Omar w Karim is however not a targetable atomic

entity and could not combine with a verb as an external argument.8

Another difference between the DP+&P concatenate Omar w Karim and a regular

constituent is that the DP does not c-command the &P. There is no branching node

dominating DP that dominates &P. Interface conditions not requiring c-command should

have no problem accepting the DP+&P concatenate. It only lacks the ability to be

targeted as a unit. Conditions requiring c-command cannot be satisfied by a structure like

in (34). The LCA (Kayne 1994) requires this and at the PF such structures must have

been Labeled in order to be interpreted. I argue below for optional late-Labeling.

Given this we build the structure below by Merging (Concatenate and Label)

In this section I will show how my approach to coordination can account for these

facts. I will begin with post-verbal subjects with singular agreement.

3.1. Post-Verbal, Singular. With the decomposition of Merge and its relation to

adjuncts, we now have two ways to compose coordinated subjects. In this section

we will concern ourselves with coordinated elements in which only the Concatenate

operation has applied (39).

DPKarim

Say that the above structure was the coordination of Omar and Karim from (36).

The DP Omar in this structure is singular and as such should precipitate singular

agreement on any verb it may serve as a subject for. As a DP, Omar is also a

targetable entity for introduction as an external argument. The complex Omar w

Karim is however not a targetable atomic entity and as such could not combine with

a verb as an external argument.

Given this we build the structure below by Merging [DP Omar ] as the argument to

a V.10 The adjunct phrase, having already Concatenated with the DP, will of course

maintain that relationship.

10 I will use this as shorthand for Concatenate and Label.

17

Page 17: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

17

[DP Omar] as the argument to a V. The adjunct phrase, having already Concatenated with

the DP, will of course maintain that relationship. The DP Karim will, by hypothesis,

receive the same thematic role as the DP that its host &P Concatenated with.

(35)

A T-head will eventually be introduced into the derivation and the verb-head will

move to that higher position. Following Pesetsky and Torrego 2004 the T-head will scan

its c-command domain and find only [DP Omar] to agree with. This will allow singular

agreement to arise on the verb like we see in (33).

3.2 Pre- and Post-Verbal, Plural

Just as it was possible for the coordinated subject to enter into the derivation without

having Labeled, so too can it Merge with the V having both undergone Concatenate and

Label. This will work like traditional coordination and thus spur plural agreement. In

effect, we have explained the fact that post-verbal coordinated subjects in Arabic can

cause either plural or singular agreement on the verb. Recall that this optionality is

something that the Aoun, Benmamoun, and Sportiche analysis could not predict.

The verb-head will move to a higher position and eventually a T-head will be intro-

scan its c-command domain and find only [DP Omar ] to agree with. This will cause

singular agreement to arise on the verb like we see in (36).11

3.2. Post-Verbal, Plural. Just as it was possible for the coordinated subject to

enter into the derivation without having Labeled, so to can it Merge with the V having

both undergone Concatenate and Label. This will work like traditional coordination

and thus spur plural agreement.

11 Arabic allows in-situ subjects which lets this be possible. Polish and English also allow in-situsubjects and in turn permit such conjunct sensitive agreement. Polish data from Citko (2004).

(ii)There was a man and a woman in the room.

I unfortunately lack space to get into a su!ciently comprehensive discussion of cross-linguistic facts.

18

Page 18: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

18

The initial position of the Labeled coordinated subject does not need to be its final

one. As an atomic element and a maximal projection it is a prospective target for a

movement operation. Arabic is such that its subject sometimes do move to Spec,TP and

we thus expect that coordinated subjects can do so as well, as long as they have Labeled.9

In other words, if there is Subject-Verb order then it is necessary that the coordinated

subject was Labeled and thus spurred plural agreement. Recall that Munn’s analysis had

no way of predicting this lack of optionality in Subject-Verb constructions. Under this

analysis, the restriction falls out from independent constraints on syntactic operations.

3.4 Summary

Compared to the previous analyses, the decomposed Merge analysis straightforwardly

predicts the fact that agreement varies when the subject is post-verbal but is constrained

when pre-verbal. We can reprise our table from above to show this graphically.

(36)

We can now also explain the reciprocal facts discussed earlier. In (5) only plural

subjects licensed reciprocal objects. That is, only coordinated subjects that have

undergone Label can fully c-command (and thus license) reciprocals.10 This extends to

other instances in which plural agreement correlates with acceptability. Aoun,

Benmamoun, and Sportiche (1999) show that “plurality seeking” elements (in the sense

singular DP is in play syntactically speaking in the instances where there is singular

agreement.

3.5. Summary. Compared to the previous analyses, the decomposed Merge analysis

straightforwardly predicts the fact that agreement varies when the subject is post-

verbal but is constrained when the subject is pre-verbal. We can reprise our table

from before to show this graphically.

further articulate the theory of Decomposed Merge.

4.1. Quantification. In discussing the shortcomings of the bi-clausal analysis it was

noted that a certain type of coordinated subject could e!ect singular agreement pre-

verbally. As seen below, when a universally quantified noun phrase is coordinated

with a noun phrase that contains a bound pronoun, singular agreement is licit. Given

the discussion above, how can we account for this fact?

4 Extending the Analysis

In this section I show that the decomposed analysis handles the intransigent data plaguing

the other accounts. In doing so I will further articulate the theory of Decomposed Merge.

4.1 Quantification

In discussing the shortcomings of the bi-clausal analysis it was noted that a certain type

of pre-verbal coordinated subject could effect singular agreement. Universally quantified

noun phrases coordinated with a noun phrase that contains a bound pronoun cause

singular agreement. Given the discussion above, how can we account for this fact?

(37) kull wəәld w bba-h mša (MA)

every boy and father-his left.SG

‘Every boy and his father left.’

For quantifier-variable binding to work, the quantifier phrase must c-command

the pronoun. Under the style of coordination assumed here, this is not difficult. This is

shown below with English words used for Arabic structures for the sake of convenience.

Page 20: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

(38)

But if Label had not taken place, there would be no c-command relation between

quantifier and pronoun and the sentences would be ungrammatical. If it is necessary to

Label in this instance, we fail to predict the variability in agreement. Only plural

agreement should be possible, pre- and post-verbally. But a deeper look at they way the

quantified noun phrases work in Arabic will save us from this unwanted conclusion.

Benmamoun (1999) argues for an analysis of Arabic quantified noun phrases in

which the nominal begins the derivation as a specifier to a quantification phrase. The QP

head (every) head-moves to the commanding D head position as in (39).

(39)

Deriving possessive phrases in Arabic involves a very similar operation. Ritter

(1987, 1991) and Mohammad (1988) derive possessive phrases like (40) from a structure

in which the possessor is the specifier to a noun phrase that the possessed heads (41)

For this quantifier-variable binding to work, the quantifier phrase must c-command

the pronoun. Under the style of coordination we have worked out thus far, this is no

di!cult feat.

This effectively gives us two means of deriving the coordinated subject in (37). A

simple way is to coordinate the DPs, shown below before any movement:

The DP necessarily undergoes Label so as to be able to create a c-command

relation between the conjuncts and license the binding. As stated earlier, this will force

plural agreement across-the-board. But this is not the only possible derivation for the

Deriving possessive phrases in Arabic involves a very similar operation. Ritter (1987,

1991) and Mohammad (1988) propose that a possessive phrase like (49) stems from

a structure in which the possessor is the specifier to a noun phrase that the possessed

That is, the NP in (41) could coordinate with the specifier NP in (39). This is

shown in (43) before head movement of the Q to D and the cliticization of the possessive

pronoun to its host NP. In this case, the NP must Label after Concatenating with the &P

for the same reason as above. This time however, when the quantifier moves to head the

‘matrix’ DP, it is only a single DP that Merges as a subject into the structure and effects

singular agreement. This works regardless of whether the subject is pre- or post-verbal.

(43)

Note that this structure will not only effect singular agreement, it will also account

for the restrictions in agreement with normal coordinated subjects and preclude the

licensing of reciprocals and ‘plurality seeking’ adverbials like ‘together’. Structures like

(43) are not coordinated DPs but rather single DPs headed by a quantifier that involve

coordinated inner NPs. As such, they are expected to pattern like regular DPs headed by

every. That is, independent of their collective readings, subjects like that in (44) will not

license elements like ‘together’. They fail to do so for the same reason that the subject in

(45) fails to do so: there is no plural item there to license ‘together’.

The DP necessarily undergoes Label so as to be able to create a c-command relation

between the conjuncts and license the binding. As stated earlier, this will force

plural agreement across-the-board. But this is not the only possible derivation for

the subject in (46). Instead of coordinating DPs, NPs could be coordinated.

That is, the NP in (50) could coordinate with then specifier NP in (48). This

is shown in (52) prior to movement. In this case, the NP must Label after Con-

catenating with the &P for the same reason as above. This time however, when

the quantifier moves to head the ‘matrix’ DP, it is only a single DP that Merges

as a subject into the structure and can thus e!ect singular agreement. This works

regardless of whether the subject is pre- or post-verbal.

In this subsection I have shown that the decomposed merge approach to ASCA can

account for not only the restrictions in agreement with normal coordinated subjects,

but also the lack of the same restrictions when the coordinated subject contains a

quantifier as one of its subcomponents. This is a novel advantage that this approach

enjoys.

In this subsection I have shown that the decomposed Merge approach can account

for not only the restrictions on agreement with normal coordinated subjects, but also the

lack of the same restrictions when the subject has a quantifier as one of its components.

4.2 Ambiguous Readings

In discussing the shortcomings of Munn’s analysis it was noted that normal sentences

with coordinated subjects are ambiguous. No matter the verb/subject order or agreement,

the sentences allow both collective readings and distributive ones. That is, (46) can mean

either that Alya and Marwaan read a total of two stories or that they read one story.

(46)

32

agreement, the sentences can be interpreted in multiple ways. That is, (57) can mean

either that Alya and Marwaan read a total of two stories or that they read a total of one

story.

(57) !!ryit "alya w marwaan !!##a (LA)

read.SG Alya and Marwaan story

‘Alya and Marwaan read a story.’

We want to be able to capture this ambiguity with the tool developed for

differences in coordination: differential Labeling.

For the moment, let us say that (intuitively enough) unLabeled coordinations

invoke distributive readings and Labeled ones collective readings. Labeling collectivizes

the DP and going unlabeled effects a distributive reading. This agrees in spirit with

Kratzer (2007) who posits that the interpretation of collectivity/distributivity is

determined by the plurality of DPs. In her proposed system, there exist features on DPs

that must vacate the DP in order to be interpreted. These features move to their sister’s

head, which in this case would be the verb. I posit that a Labeled coordinated DP has a

feature that marks the verb with what will effect a collective reading (similar to what

Kratzer herself does for coordinated DPs).11

Phrases with structures like that in (58) would fail to have this feature. This, by

hypothesis, effects a distributive interpretation: Alya read a story and Marwaan read a

story.

Page 24: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

24

We can capture this ambiguity with the tool developed here: differential Labeling.

Assume that unLabeled coordinations invoke distributive readings and Labeled ones

collective readings. Labeling collectivizes the DP and going unlabeled effects a

distributive reading. This agrees in spirit with Kratzer (2007) who posits that the

interpretation of collectivity/distributivity is determined by the plurality of DPs. In her

proposed system, there exist features on DPs that must vacate the DP in order to be

interpreted. These features move to their sister’s head, which in this case would be the

verb. I posit that a Labeled coordinated DP has a feature that marks the verb with what

will effect a collective reading (similar to what Kratzer herself does for coordinated

DPs).11 Structures like (47) fail to have this feature. This effects a distributive

interpretation: Alya read a story and Marwaan read a story.

(47)

With distributive interpretations, sentences with structures like (47) would be true if

there were a total of two stories read. But they would also be true if Alya and Marwaan

read only one story separately. In short, the distributive reading can be true in the two

situations yet only have a single reading (see Pietroski and Hornstein 2002 for a similar

point). As such, coordinated subjects causing singular agreement are merely functionally

33

As such, we have whittled down the extension condition to merely apply to Add

and Substitute. These in turn are the formal equivalent to the Concatenate oper-

ation.14 In sum, we have reduced the extension condition to its minimal parts and

the Label operation is not one of them.

4.4. Distributive/Cumulative Readings Redux. Given our new understanding

of the extension condition, we can explain how the derivation can licitly proceed

from (60) to (61).

14 This jibes well with the conception of movement as adjunction (Chomsky (2004)). Movementcertainly must obey extension and with movement as adjunction we must be able to define extensionin a very minimal sense in light the notion of adjunction advocated here. This decomposition ofthe extension condition captures this.

29

(58)

That is, sentence like in (58) would be understood as having the distributive

meaning in (59) if no Labeling had occurred: a reading in which a total of two stories

were read.

(59) Alya read a story and Marwaan read a story.

Given the distributive interpretation in (59), the sentence in (57) would be true if

there were a total of two stories read. But it would also be true if only 1 story was read,

albeit separately by Alya and by Marwaan. That is, the sentence in (57) can be true in the

two situations yet only have a single reading (see Pietroski and Hornstein 2002 for a

similar (and more extensive) point with respect to quantifier scope in general). As such,

coordinated subjects causing singular agreement are merely functionally ambiguous, but

have only a distributive syntax and consequently a distributive logical form. The fact that

the collective reading can be inferred from the distributive one obscures the lack

structural ambiguity here.

25

ambiguous, but have only a distributive syntax and consequently a distributive logical

form. That the collective reading can be inferred from the distributive one obscures the

lack of structural ambiguity.

This same idea can capture the apparent tension in this analysis with respect to

singular agreement and collectivity. Elements requiring plurality like ‘together’ are not

allowed with singular agreement. However, ‘together’ usually tracks collective

interpretations, which are nevertheless possible with singular agreement. If it is the case

that collective agreement interpretations with singular agreement only come about via

entailment and that there is in fact no collectivity coded in the syntax or semantics, then it

is predicted that the elements like ‘together’ and ‘each other’ will be illicit in ostensibly

collective environments as seen in (48).

(48) *ža ʕomar w karim bžužhum (MA)

came.SG Omar and Karim together

“Omar and Karim came together.’

In contrast, coordinated subjects that cause plural agreement are actually

structurally ambiguous generally. One half of the ambiguity is clear enough to explain.

The subject could have Merged with the V having already undergone Label and thus

forcing both plural agreement and a collective reading. This is the only reading available

since collective readings do no entail distributive ones.

Page 26: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

The subject could also have Merged without having undergone Label. This would

allow for the distributive reading, but what about the plural agreement? In the following

section I examine how the plural agreement could be derived.

4.3 Decomposing the Extension Condition

At first glance, once the structure in (49) has been built, it could not proceed to that in

(50) without violating the extension condition of Chomsky 1995. Structure building is not

applying to the root. The D-head Omar is projecting as the Label of the coordination

having already Merged with the verb. But we will see that this sort of operation should be

allowed in a system with Concatenate and Label as operations.

applying to the root. The D-head Omar is projecting as the Label of the coordination

after having already fully Merged with the verb. This should be as egregious an

operation as en element moving from within the VP to become the DP’s specifier. But

we will see that this sort of operation should be allowed in a system with Concatenate

and Label as operations.

In Chomsky’s original formulation of the extension condition, he couches it as a

generalized transformation. In paraphrase, take a phrase marker K and add Ø (which

crucially must be external to K), following this substitute ! for Ø, thus forming the

new phrase marker K*.

When this process is viewed through our decomposed merge lens, a pivot point

emerges. After the substitution suboperation, Chomsky takes it as a given that a new27

37

In (63a-b) a DP and a &P are Concatenated, obeying extension. In (63c-d) the

same thing happens between a DP and a V. The result of the (63c-d) operations is

Labeled in (63e), but this operation is irrelevant to extension per se, it has already been

obeyed. The same goes for the final step.

As such, we have whittled down the extension condition to merely apply to Add

and Substitute. These in turn are the formal equivalent to the Concatenate operation. In

sum, we have reduced the extension condition to its minimal parts and the Label

operation is not one of them.

Given our new understanding of the extension condition, we can explain how the

derivation can licitly proceed from (64) to (65).

In Chomsky's original formulation of the extension condition, he couches it as a

generalized transformation. In paraphrase, take phrase marker K and add Ø (which must

be external to K), following this substitute α for Ø, forming a new phrase marker K*.

This process, viewed through our decomposed Merge lens, reveals a pivot point.

After the substitution operation, Chomsky assumes that a new phrase marker Labeled K*

emerges. This emergence (Label), is neither necessary nor necessarily immediate. Given

the above conceptualization, Label does not necessarily take place directly after the

substitution operation to avoid violating the extension condition. Once Ø, which is

external to K, has been added extension has been obeyed. Any further (potentially

optional) steps in the process are formally independent of the fundamental extensional

aspect of the extension condition. Labeling is one of these further steps.

As such, we have whittled down the extension condition to merely apply to Add

and Substitute. These in turn are the equivalent to the Concatenate operation.9 We have

reduced the extension condition to its minimal parts and Label is not one of them.

Given our new understanding of the extension condition, we can explain how the

derivation can licitly proceed from (49) to (50). Once the verb and the DP have Merged,

the distributive reading is a possible interpretation. The verb (or whatever analogous

object that determines thematic roles) registers this initial Merger. Following the Kratzer

2007, the DP ‘releases’ features determineing collectivity/distributivity. Merge the

singular Omar with the verb and a feature that effects a distributive reading is released

onto the verb; Merge the plural Oman and Karim and a collective reading is released.

If it is assumed that the coordinated subject is introduced into the specifier position

Page 28: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

28

of a phase head (in the sense of Chomsky 2001 and subsequent work), the phasal

projection can undergo Spellout and the verb can maintain its collective/distributive

reading. If the degree of opacity (the strength of the Phase Impenetrability Condition of

Chomsky 2001) after Spellout of the phase is sufficient to preclude any overwriting of the

collective/distributive reading on the verb, then the DP+&P complex can undergo Label

and become available for plural agreement with the T head once it is Merged into the

structure. With cyclic Spellout, the phase in which collective/distributive readings are

determined can see the subject as it appears in (49) while the phase in which agreement is

determined can see the subject as it appears in (50). We can thus explain why post-verbal

coordinations with plural agreement are ambiguous. The subject can also move to a pre-

verbal position and thus pre-verbal coodinations are predicted to be ambiguous.

4.4 Quantifiers Redux

As we saw above, regular coordinated subjects are ambiguous with respect to

distributivity and collectivity whereas the quantified subjects are unambiguous. Neither

the bi- nor the mono-clausal previous analyses handle this. But the decomposed Merge

analysis suggests a simple account for this. Pronouns bound by quantifiers must be c-

commanded by them as a derivational condition. In order to effect c-command, the

coordination must Label immediately and in turn cause collective readings.

Contra proposals such as those found in Chomsky 1993, Fox and Nissenbaum

2004, and Lebeaux 2009 there are alternative arguments that binding conditions are

reducible to syntax-internal principles as opposed to LF-interface ones (Lidz and Idsardi

Page 29: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

29

1998, Hornstein 2001, Reuland 2001, Kayne 2002, Zwart 2002, Hicks 2008, Takano

2010, and Drummond, Kush, and Hornstein 2011). According to these, the relevant

conditions on binding must hold throughout the derivation. At no applicable time in the

derivation of a grammatical sentence is the condition violated.

The derivational approach to binding that I adopt is that at some point in the

derivation, coreferential elements are sisters to each other. As in (51) In the course of the

derivation α will move and serve as the antecedent to β. The binding constraints are then

predicted to track the movement restrictions on α (roughly as in Kayne 2002).

(51) [α β] [αi [ γ […ti β…]

The restrictions on quantifier-pronoun binding across coordination can similarly

be accounted for in a manner that tracks movement restrictions. The derivation of (52)

would involve a stage in the derivation where every boy and his are sisters (53). As the

configuration in (53) is not yet coordinated with anything it should not be subject to the

coordinate structure constraint. Movement of every boy to the root in (54) is allowed.

(52) every boy and his dog

(53) [& [[every boy his] dog]]

(54) [[every boy]i [& [[ ti his] dog]]]

Page 30: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

30

However, if instead of the initial movement of every boy a different noun were

introduced, this would create the full coordinate structure (55). Movement of every boy

should no longer be possible and binding across coordination should not occur across

non-adjacent conjuncts. Indeed, the pronoun in (56) does not have the bound reading.

(55) [& [the instructor [& [[every boy his] dog]]]]

(56) Every boy (and) the instructor and his dog.

It is possible to give a derivational account of the restrictions on this particular

binding configuration and the movement must result in a c-command relation between

the moved element and the pronoun. When a pronoun in the second conjunct is not c-

commanded by the relevant quantified NP, the sentence lacks a bound pronoun reading:

(57)a. *[A lunchlady from [every school]i] and itsi janitor attended

b. *[[Every presidenti’s] daughter] and hisi wife attended.

If the antecedent must c-command the pronoun for cross-coordination binding

purposes and this is part of a derivational constraint, then it must be that the Label sub-

operation occurs as soon as possible in these cases. This binding requires c-command and

the c-command in turn requires Label. The fact that Labeling is immediate here has

repercussions for meaning. We are never going to have a situation like (49) above and

thus never going to have the possibility of distributive readings with this sort of subject.

Page 31: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

31

The Label operation always occurs prior to Merger of coordinated subject and verb. From

this we can see that the only grammatical sentences with this sort of coordinated subject

must have collective readings. They can never avoid Label and in turn distributivity.

This makes a prediction. If a language does not have a c-command condition on the

binding of pronouns by quantifier expressions across coordination, then it should allow

ambiguous distributive/collective readings of those constructions (and vice versa). If a

language has such a c-command condition, it will only allow collective readings.

This is borne out. LA and MA only allow collective readings in the relevant

constructions. They also require quantified expression to c-command their co-indexed

pronouns across coordination. In the sentences below, the relevant pronoun is feminine

and the only c-commanding antecedent is masculine. Native speakers find that the

feminine pronoun necessarily referred to a third party female and could not be bound by

the quantified expression that is not in a c-commanding position.

(58) a. *[ʔəәsteez [kəәll mara]i] w ʔəәbnai daraho (LA)

teacher each womani and child.heri left.PL

‘The (male) teacher of each woman and her child left.’

b. *[wəәld [kull mra]i] w xu-hai mšaw (MA)

child each woman and brother-her left.PL

‘The (male) child of each woman and her brother came.’

Page 32: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

32

However, a reviewer notes that the analogous sentence in Egyptian Arabic (EA)

does not require c-command:

(59) [bint [kul raʔiis]i] wi-miraat-u-i kaan-uu fi-l-ðaflah

daughter every presidenti and-wife-hisi were.PL at-the-party

‘The daughter of every president and his wife were at the party.’

As is predicted, for the reviewer the equivalent of ‘Every man and his son got-

in.sg’ is ambiguous between collective and distributive readings in (EA). That is, c-

command is not an obligatory condition on the binding of pronouns by quantified

expressions across coordination in that dialect. Without the need for c-command,

Labeling should be optional here and if Labeling is optional we expect ambiguity.

5 Conclusion

I have argued in this reply that the previous accounts of Arabic conjunct-sensitive

agreement are inadequate. Instead I offer analysis which explains data more completely

by means of decomposed Merge. Further, a new conception of the extension condition

emerges. Labeling is not relevant to whether an operation obeys extension. Instead, it is

only important that the root is targeted for the introduction of a new element and other

operations can apply to non-roots, counter-cyclically only superficially.

1For the sake of continuity, in the Arabic examples used here I recruit the same quasi-IPA

representation that is used by Aoun, Benmamoun, and Sportiche.

2 For simplicity’s sake, the generic use of Arabic in this paper and in the title refers to

Moroccan Arabic and Lebanese Arabic. The examples in this paper are mostly from

Moroccan Arabic (MA), but the generalizations extracted from this data carry over to

Page 37: they can move to pre-verbal positions. This correctly ...ling.umd.edu/assets/publications/Arabic_Agreement_CB.pdf · they can move to pre-verbal positions. This correctly predicts

37

Lebanese Arabic (LA). I note the few examples for which the speakers differ.

3Aoun, Benmamoun, and Sportiche, an anonymous LI reviewer, and my informants note

that singular agreement in these instances correlates with an intonation break between the

conjuncts. Another reviewer disagrees with grammatical status attributed to example (8).

I do not have an account for these facts, though I do address the difference between plural

and singular agreement in these instances in a later section.

4The interpretations here hold no matter how word order and plurality marking are

permuted. It should be noted that one Lebanese Arabic speaker found singular marking to

unambiguously correlate with a distributive reading. I have no account for this fact. My

Moroccan Arabic informants uniformly found the sentences ambiguous.

5See Hornstein 2009 for arguments against Chomsky's reformulation of adjunction as

pair-Merge which could potentially avoid this problem.

6Precursors to this theory can be found in Chametzky 2000 and Uriagereka 2002 and is

further discussed in Hornstein and Nunes 2008.

7Take the dashed line to indicate Concatenation with Labeling. Note that there is no c-

command relation between the two atomic elements.

8The question understandably arises as to exactly what kind of syntactic object the

DP+&P concatenate is. The only real distinction between it and a traditional constituent

is that, being un-labeled, it cannot be targeted as a single entity or unit. Its constituent

parts, the two things Concatenated, can indeed be targeted, but since the grammar can

only manipulate constituents, the constituent parts cannot be addressed together in any

operation.

9The analysis here crucially relies on syntactic movement of the subject from a VP-

internal position to a VP-external one. This is an assumption that is not without

controversy. Demiredache 1989 (as well as Fassi Fehri 1993 and Soltan 2006, 2007)

argue that subject-verb word order in Arabic is derived via base-generation of the subject

in the left periphery. I follow Aoun, Benmamoun, and Sportiche (as well as Tucker 2007)

in assuming that the subject moves to spec,TP from a lower, VP-internal position.

10Harbert and Bahloul 2002 note that this does not extend to Standard Arabic. Singular

agreement with reciprocals is licit. The analysis offered here cannot account for this. See

Soltan 2006, 2007 for a good account for this and other Standard Arabic agreement facts.

The Soltan approach is similar to the present one. He argues for the optional late Merger

of coordinated subjects qua adjuncts. However, this approach cannot (among other

things) account for the differences in agreement with quantifiers discussed here.

11Kratzer’s system is considerably more complex than this, but the idea that the nature of

the arguments determines semantic features of the verb is maintained.
