what is diffrent between MUCH and A LOT when they come whithout noun at the end of sentences ??? thanks?

Answer 1

I think 'much' follows a negative, 'He doesn't like it much', whereas 'a lot' is positive, 'He likes it a lot'. This is only in the context that you have suggested.

Answer 2

Much and a lot mean the same thing and are usually interchangeable.
Example: I don't eat much. I don't eat a lot.
These sentences mean the same thing.

When to use 'much' and when to use a lot depends on the sentence, and is a matter of style.

You could say, "I don't like her much". Not "I don't like her a lot".
A farmer might ask, "How much wheat did you plant?"
Answer: "I planted a lot", not, "I planted much".
Which term sounds better does not follow any rule that I know of and has to be decided case by case.
