A little | A few• Form• (a) few + plural countable noun

(a) little + uncountable noun• Meaning• We use a few and a little to mean a small quantity or a small number.

– I have a few friends (a small number)– I have a little money (a small amount)

• We use few and little to mean "not enough", or to give the small quantity/number a negative meaning.– I have few friends. (a small number, and I wish I had more)– I have little money. (a small amount, and I wish I had more)

• Few and little without "a" are quite formal. In spoken English it is more common to say only a few / little or not much / many.– Few people came to the meeting - more formal– Only a few people came to the meeting - less formal– Not many people came to the meeting - less formal

• If we use a few or a little before a pronoun or determiner, we use of.– A few of them went to the cinema.– He only kept a little of his money with him.
