Choosing some, any and quantity phrases

Some: often appears in affirmative statements and offers or requests: We have some spare wire. Would you like some tea?Questions with some are natural when offering or expecting a yes.

Any: often appears in negatives and open questions: We don’t have any tape. Do you have any tools?These are useful patterns, not fixed rules for every context. Much and many are common in questions and negatives; a lot of is often more natural in ordinary affirmative statements.

A piece of: makes one unit of an uncountable noun countable: a piece of cake, a piece of advice, a piece of information.For other nouns, choose a natural measure or container, such as a bottle of water.

Watch Out & Common Mistakes

Check the noun’s meaning, its countability and the words that agree with it.

Countability can change with the meaning.

Food names may be uncountable when they mean food as a substance and countable when they mean separate servings or types: We bought some chicken (food); We saw two chickens (birds). Learn the meaning in each sentence instead of memorising a short list as an absolute rule.

2. Using a/an with a general material

BetterShe bought two sheets of paper for the labels.

Paper means writing material here. Count blank sheets with sheets of paper; papers can mean separate documents or reports.

3. Mixing much and many

BetterHow many volunteers are here?

Volunteers are countable people, so ask how many.

4. Matching a little with a plural noun
