Quantifiers indicate the amount of a name. Are responses to the question "How many?" Like articles, quantifiers define a name and are always situated in front of the name. You can use some only with countable nouns, other nouns only and some with both.

COUNTABLES are the things that can be counted.

Ex:  HotelBicycle                 Pen, friend, car, etc.

Uncountables  are those who cannot be counted.Ex:Beer                                                MilkWater                                              

In the following summary we can study, how and when to use them.

Expresses the idea of great quantity. It is used especially in negative and interrogative sentences with plural count noun. You can use "many" in affirmative sentences, although not very common. Normally, we use other quantifiers like "a lot.“

Examples:We have many friends. There are not many tourists. 

Also combined with "too" or "so" to express the idea of  too much or a viewpoint on a number.

Example:There are too many changes for me. There are so many things I want to do! 

As "many", expresses the idea of large amounts and is used especially in negative and interrogative sentences. The difference to "many" is that we use "much" only with singular nouns. You can use "much" in affirmative sentences, although it would be more formal and not so common.

Examples:There is not much time. We have much to do! 

As "many," can also be combined with "too" or "so" to express the idea too much, or point of view on an amount.

Example:There is too much work. (Hay demasiado

trabajo.)We have so much work to do! (¡Tenemos tanto

trabajo que hacer!)

It is used both for names or singular countable nouns, such as for names or plural countable nouns. It is used in affirmative sentences and questions (to say something), is substituted "any" in negative or interrogative sentences. Means an indefinite quantity, but limited.

Examples:She has some apples. There is some milk in the kitchen. (Are there some tourists? Is there some sugar? 

It is used in the same contexts as "some", but in negative or interrogative sentences.

Examples:I do not have any cats. (No tengo ninguno gato.)Frase negativa/nombre incontable:He does not have any money. (No tiene dinero.)Frase interrogativa/nombre contable:Are there any changes? (¿Hay algunos cambios?)Frase interrogativa/nombre incontable:Is there any milk? (¿Hay leche?)

Unlike the particle "no," "none" can be used unless accompanied by a name, accounting or uncountable. Therefore used to go to the end of sentence and the only answer to a question that refers to quantities

Examples:How many pencils are there? None. There are no pencils. How much money do you have? None. I have no money. 

Idea expressing large quantities. It can be used with nouns or uncountable nouns and accounting. Unlike "many" and "much", do not use them in interrogative sentences. In general, "lots of" is more informal.

Examples:Countable noun:He has a lot of books. Countable nounHe does not have a lot of books. Uncountable noun:I have lots of money. Uncountable noun:I do not have a lot of money. 

Express a small amount and are used only with uncountable nouns. The decision to use"little" or "a little" reflects an opinion on the amount. If you are using "a little" means a positive opinion on the quantity, and if you use "little" implies a negative opinion.

Examples:questionsDo you have a little money? Positive sentences:We have little time. 

Expressing a small number. "A few" may indicate a sufficient number. Are used only withcount nouns. As seen above, the decision to use "few" or "a few" reflects the opinion ofthe amount specified. "Few" means the amount of negative, and "a few" describes a positive way.

Examples:Questions:Do you have a few dollars? (¿Tienes unos dolares?)Positive sentences:There are few tourists here today. (Hay pocos

turistas aquí hoy.)
