Much vs More-Usage

[harry1999]

I am quite confused about the usage of Much and More.
When can we use only much or more? How can it be decided to use much or more in a sentence?

I have some examples:

1. I am more demoralized vs I am much demoralized.
2. I am more happy vs I am much happy.
3. I am more lucky vs I am much lucky.
4. The tea I drank today in the morning was much better taste vs The tea I drank today in the morning was more better taste.
5. This is a still more complicated explanation vs This is a still much complicated explanation.
6. I need more time vs I need much time

Please help me out..
Can you please elucidate the difference?

Thanks

1. I am more demoralized vs I am much demoralized.
Both fine with the right context.

2. I am more happy vs I am much happy.
We rarely say "more happy". We say "happier".

3. I am more lucky vs I am much lucky.
We don't say "more lucky" often. We say "luckier". We wouldn't say "much lucky".

4. The tea I drank today in the morning was much better taste vs The tea I drank today in the morning was more better taste.
The tea I drank this morning tasted much better than the tea I drank yesterday.

5. This is a still more complicated explanation vs This is a still much complicated explanation.
This is an even more complicated explanation than...

6. I need more time vs I need much time
"I need more time" is fine. "I need much time" is technically OK but rarely used.

Please help me out..

"Much" is an intensifier, like "very".
"More" is a comparative.

Using "much" in place of "very" is a little archaic. It is possible to say "I am much despondent" but it would sound extremely unnatural. We would say "I am very despondent".

"I am more despondent" requires further information.
"I am more despondent than you [are]."
"I am more despondent than I was yesterday."

Please be aware that (confusingly) you will hear "much more" together. However, "much" is still the intensifier here, meaning "a lot".

I have much more money than you do.
There is much more snow than there was last year.
