A lot of, lots of with a noun
We use a lot of and lots of in informal styles. Lots of is more informal than a lot of. A lot of and lots of can both be used with plural countable nouns and with singular uncountable nouns for affirmatives, negatives, and questions:
- We’ve got lots of things to do.
- That’s a lot of money.
- There weren’t a lot of choices.
Can we use the quantifiers in formal writings, and is there any substitute for them?
