Much, Many, and A Lot Of: Choosing the Natural Quantity Word

The grammar is simple: many goes with countable plural nouns, much goes with uncountable nouns. Natural usage adds one useful detail.

Many + plural countable nouns

Use many with things you can count individually: many students, many questions, many lessons, many ideas.

Much + uncountable nouns

Use much with nouns treated as a mass or concept: much time, much money, much information, much advice.

Information and advice are uncountable in standard English. We do not normally say informations or advices.

A lot of works with both

A lot of is common and natural in positive everyday sentences.

We have a lot of students this term.
I have a lot of work today.

Why much can sound formal in positive sentences

I have much work is grammatical, but in ordinary conversation I have a lot of work is more natural. Much and many are especially common in questions and negatives.

Do you have many questions?
We don’t have much time.

How much? How many?

How many + plural countable noun: How many lessons do you have?

How much + uncountable noun: How much time do we need?
