Indefinite adjectives talk about a person or thing without naming it exactly. They leave the noun general, not specific. In some people, any answer, and each child, the adjective gives a sense of amount, choice, or group, but it does not point to one exact person or thing the way a Demonstrative Adjective does. They usually come before the noun they modify: some water, every day, no problem. If you remove the adjective, the noun becomes more open and less defined.

Some often appears in affirmative statements when the speaker refers to an unknown or limited amount: We have some bread. It also appears in offers and requests: Would you like some tea? Any is common in questions and negatives when the amount is not fixed: Do you have any money? I do not have any time. With countable nouns, some and any can modify a plural noun: some books, any questions. With uncountable nouns, they modify the noun in its singular form: some milk, any advice. These adjectives work with quantity, so they often appear in everyday speech about food, time, and items, alongside patterns taught in Descriptive Adjectives.

Some and any with quantity

Usage	Explanation
Affirmative amount	Use some in affirmative statements when the amount is not exact but is positive.
Questions about offer or request	Use some in questions when you offer something or ask for a positive answer.
Negative amount	Use any in negative sentences when the amount is not present or not known.

Each and every both mean all the members of a group, one by one. They usually come before a singular noun: each student, every room. After them, the verb is singular: Each child has a ticket. Every often describes a whole group as a single idea, while each often feels more individual and separate. Each can also stand alone when the noun is understood from the context: Each was given a form. Every does not usually stand alone in the same way.

Each and every before singular nouns

Idea
Use each to talk about items one by one in a group.
Use every to mean all the people or things in a group.

In questions, any can mean it does not matter which one: Do you want any chair, or do you want the blue one? It asks about choice without selecting a specific item. In negative sentences, any shows that no single item is included: I do not want any help. She did not buy any oranges. This use appears with both countable and uncountable nouns. It also works when the speaker means no limit at all: Any student can join the club. Here, any gives freedom, not a fixed choice.

Any meaning no matter which

Usage	Explanation
Open choice in questions	Use any in questions when the choice is open and no specific one is needed.
Open choice in negatives	Use any in negative sentences when the meaning is no matter which or no amount at all.
Free choice after if	Use any after if when you mean that one choice is fine.

No expresses negation and comes directly before a noun: no answer, no money, no workers. It replaces not any in a shorter form. None stands alone and does not come before a noun: None of the answers are correct. None of them is here. With uncountable nouns, none of can introduce the noun: none of the water. In everyday English, no is common before nouns, while none is common when the noun is already clear from the context. For noun groups and quantifying forms, Interrogative Adjectives show a different kind of specification through questions.

No and none for negation

Idea
Use no before a noun to show that something is absent.
Use none alone when you do not want to repeat the noun.

Few and a few both describe a small number of countable things, but the feeling is different. Few suggests that the number is small in a disappointing way: Few people came. The speaker expects more. A few is more neutral or positive: A few people came. There were some, and that is enough. They come before plural countable nouns: few options, a few ideas. These forms do not take uncountable nouns. The choice between them changes the attitude toward the amount, not the amount itself.

Small number with countable nouns

Usage	Explanation
Not many and slightly negative	Use few when a small number feels disappointing or less than you want.
Some but not many	Use a few when a small number is enough or still positive.
Small number in friendly contrast	Use a few to show that the number is small but useful.

Little and a little describe a small amount of uncountable things. Little carries a negative feeling and suggests that the amount is too small: There is little hope. She has little time. A little means a small amount, but enough to matter: There is a little hope. Add a little water. They come before uncountable nouns and do not change for number. The difference between them is attitude: one sounds lacking, the other sounds present but limited. For more about how these forms fit with noun types, see Adjective Placement and Adjective Formation.

Small amount with uncountable nouns

Usage	Explanation
Not much and slightly negative	Use little when a small amount feels disappointing or not enough.
Some but not much	Use a little when there is a small amount that is still useful.
Gentle positive quantity	Use a little to show a small amount in a positive way.

Other means different or additional. It usually comes before a plural noun or an uncountable noun: other houses, other information. It can also appear with the: the other seat, the other students. Another means one more or a different one and comes before a singular countable noun: another cup, another chance. It can also stand alone when the noun is understood: Have another. Use other when the noun is plural or uncountable, and another when you mean one extra item or one additional person.

Different one and one more

Usage	Explanation
Different from the first one	Use other to mean different people or things.
One more singular item	Use another when you mean one more of the same kind.
Additional choice in a series	Use another when you want an extra item or a new choice.
