We use many before plural (countable) nouns and much before uncountable nouns. We use them in negative sentences and questions. We don’t normally use them in affirmative sentences.
Note that we don’t normally use much/many in affirmative sentences, but we can use too much and too many in affirmative sentences.
We use how many and how much to ask about quantity.
We use a lot of or lots of (more informal) before both plural (countable) and uncountable nouns. We normally use them in positive sentences.
We must always use a lot of or lots of including of before a noun. However, we can use the expressions a lot or lots (without of) at the end of a sentence.
We use (a) few before plural (countable) nouns and (a) little or a bit of (more informal) before uncountable nouns.
A few means ‘some but not many; enough’, and a little means ‘some but not much; enough’.
Few/little mean ‘almost none; not enough’.
Normally, the difference between a few/little (WITH a) and few/little (WITHOUT a) is that a few/little is positive in meaning, and few/little is negative. Compare:
We use some in affirmative sentences and any in negative sentences and questions.
Both some and any can be used before countable and uncountable nouns. But if we use them before a countable noun, the noun must be in the plural form.
We use some (NOT any) in interrogative sentences when we are offering or requesting (=asking for) something.
