Much is used as a determiner before a noun, especially in a negative sentence and questions:
- I don’t watch much TV these days.
- Jack said he usually doesn’t drink much wine.
- We didn’t get much snow in NYC last winter.
Keep in mind we generally don’t use much in a positive sentence, unless we use much with too and so:
- Jane said she drank so much wine last night.
- My dog has too much energy, so we walk her twice a day.
We also use much as a pronoun:
- Bob said there was a lot of pizza at the party, but he didn’t eat much.
- Joe said there was a lot of litter in the park, but I didn’t see much.
We use not much of a when we refer to someone who is not good at or doesn’t like doing something:
- I’m not much of a beer drinker.
- Blair said she is not much of a skier.
We also use much as an adverb meaning to a large extent:
- We went to the club but we didn’t dance much.
- I don’t know much about golf, do you?
It’s also possible to use much as an adverb before a comparative adjective:
- This tomato sauce tastes much better that the one I made last week.
- I think Jenny is much more beautiful than Blair.
We use as much as to mean the same degree as~
- Jane said she danced as much as Maggie did.
- Bob doesn’t work as much as Frankie does.
We use very much before a past participle in a passive sentence:
- Brad was very much bothered by the neighbor’s barking dog.
- We were very much worried about Jane after she lost her job.
