Generative grammar

In theoretical linguistics, generative grammar refers to a particular approach to the study of

syntax. A generative grammar of a language attempts to give a set of rules that will correctly

predict which combinations of words will form grammatical sentences. In most approaches togenerative grammar, the rules will also predict the morphology of a sentence.

Generative grammar originates in the work of Noam Chomsky, beginning in the late 1950s.

Early versions of Chomsky's theory were called transformational grammar, and this term is still

used as a collective term that includes his subsequent theories. There are a number of competingversions of generative grammar currently practiced within linguistics. Chomsky's current theory

is known as the Minimalist program. Other prominent theories include or have included head-

driven phrase structure grammar, lexical functional grammar, categorical grammar, relational

grammar, link grammar and tree-adjoining grammar.

Chomsky has argued that many of the properties of a generative grammar arise from an "innate"universal grammar. Proponents of generative grammar have argued that most grammar is not the

result of communicative function and is not simply learned from the environment (see poverty of

the stimulus argument). In this respect, generative grammar takes a point of view different from

cognitive grammar, functional and behaviorist theories.

Most versions of generative grammar characterize sentences as either grammatically correct(also known as well formed) or not. The rules of a generative grammar typically function as an

algorithm to predict grammaticality as a discrete (yes-or-no) result. In this respect, it differs from

stochastic grammar, which considers grammaticality as a probabilistic variable. However, some

work in generative grammar (e.g. recent work by Joan Bresnan) uses stochastic versions of

optimality theory.

Frameworks

There are a number of different approaches to generative grammar. Common to all is the effort

to come up with a set of rules or principles that will account for the well-formed expressions of a

natural language. The term generative grammarhas been associated with at least the followingschools of linguistics:

Transformational grammar (TG)o Standard Theory (ST)o Extended Standard Theory (EST)o Revised Extended Standard Theory (REST)o Principles and Parameters Theory (P&P)

Government and Binding Theory (GB) Minimalist Program (MP)

Historical development of models of transformational grammar

Main article: Transformational grammar

The oldest known generative grammar that is still extant and in common use is the Sanskrit

grammar of Pini, called the Ashtadhyayi, composed by the middle of the 1st millennium

BCE.[1]

Generative grammar has been under development since the late 1950s, and has undergone many

changes in the types of rules and representations that are used to predict grammaticality. Intracing the historical development of ideas within generative grammar, it is useful to refer tovarious stages in the development of the theory.

Standard Theory (19571965)

The so-called Standard Theory corresponds to the original model of generative grammar laid outin Chomsky (1965).

A core aspect of Standard Theory is a distinction between two different representations of a

sentence, called Deep structure and Surface structure. The two representations are linked to each

other by transformational grammar.

Extended Standard Theory (19651973)

The so-called Extended Standard Theory was formulated in the late 1960s to early 1970s.

Features are:

syntactic constraints generalized phrase structures (X-bar theory)

Revised Extended Standard Theory (19731976)

The so-called Revised Extended Standard Theory was formulated between 1973 and 1976. Itcontains

Restrictions upon X-bar theory (Jackendoff (1977)). Assumption of the COMP position. Move

Context-free grammars

Generative grammars can be described and compared with the aid of the Chomsky hierarchy

proposed by Noam Chomsky in the 1950s. This sets out a series of types of formal grammars

with increasing expressive power. Among the simplest types are the regular grammars (type 3);

Chomsky claims that regular grammars are not adequate as models for human language, becauseall human languages allow the center-embedding of strings within strings.

At a higher level of complexity are the context-free grammars (type 2). The derivation of a

sentence by a grammar can be depicted as a derivation tree. Linguists working in generative

grammar often view such derivation trees as a primary object of study. According to this view, asentence is not merely a string of words, but rather a tree with subordinate and super ordinate

branches connected at nodes.

Essentially, the tree model works something like this example, in which S is a sentence, D is a

determiner, N a noun, V a verb, NP a noun phrase and VP a verb phrase:

The resulting sentence could be The dog ate the bone. Such a tree diagram is also called a phrasemarker. They can be represented more conveniently in text form, (though the result is less easy

to read); in this format the above sentence would be rendered as:

[S [NP [D The ] [N dog ] ] [VP [V ate ] [NP [D the ] [N bone ] ] ] ]

Chomsky has argued that phrase structure grammars are also inadequate for describing natural

languages, and has formulated the more complex system oftransformational grammar.

Grammaticality judgments

When generative grammar was first proposed, it was widely hailed as a way of formalizing theimplicit set of rules a person "knows" when they know their native language and produce

grammatical utterances in it (grammaticality intuitions). However Chomsky has repeatedly

rejected that interpretation; according to him, the grammar of a language is a statement of what itis that a person has to know in order to recognize an utterance as grammatical, but not a

hypothesis about the processes involved in either understanding or producing language.
