A lot of vs. Lots of, Much vs. Many, Few vs. Little



We use these words as quantifiers that come at the start of noun phrases and they tell us something about quantity.


A lot of vs. Lots of
A lot of and lots of are used to express that there is a large quantity of something.
We use a lot of in positive sentences, negative sentences and questions. This expression can be used with countable or uncountable nouns.


Examples:
- There are a lot of dogs in their house. (Countable noun)
- I have a lot of time to answer your questions. (Uncountable noun)
- I saw a lot of people waiting in the queue. (Countable noun)
- We did have a lot of fun, didn't we? (Uncountable noun)


Note: We use lots of in positive and negative sentences, however it is more informal. It can be used with countable or uncountable nouns, and occasionally in questions.


Examples:
- We have lots of time to catch the plane, lets relax. (Uncountable noun)
- There are lots of people in the queue today. (Countable noun)
