a feeling of happiness that something unpleasant has not happened or has ended.

[capcap23]

Relief; a feeling of happiness that something unpleasant has not happened or has ended. source.

Is this "that" complement of "happiness" or "feeling"? I look it up for "happiness" but couldn't find any example for taking complement and as far as I know, when there are two clauses modifying one noun, they take a comma between them.

The antecedent of the relative 'that' is the NP a feeling of happiness, the headword of which is 'feeling'.

You know I'm no expert on grammar but I'm sure that's not right.

I don't think that is a relative pronoun here and so has no antecedent. If you replace it with which, you'll hear this quite clearly.

I think it can be called a complementizer, introducing a that-clause complement. I don't know the precise terminology.

Hopefully, PaulMatthews will step in and set things straight.

In order to improve my grammar.

For example "Mead also drew a conclusion that some find startling - that not only the self but also the human mind is a social product." In this sentence, it is seperated with hyphen, I don't know why.
Another one, "I did not believe his original statement, that he had won the lottery, until he proved it to us." In this one, I know why it is seperated. Because it isn't essential to the meaning of the sentence as in relative clauses.

I want to know when to use dash, comma or nothing for when I will write an essay, application, etc.

I think In original post, that isn't essential to the meaning. What feeling it is was stated "feeling of happiness".

I doubt this will help improve your use of grammar. You just need to understand the meaning and use of the sentence.

For example "Mead also drew a conclusion that some find startling - that not only the self but also the human mind is a social product." In this sentence, it is separated with a hyphen. I don't know why.

It's not a hyphen, it's a mistyped dash. You can look up how to use dashes quite easily.

Another one, "I did not believe his original statement, that he had won the lottery, until he proved it to us." In this one, I know why it is separated: it isn't essential to the meaning of the sentence as in relative clauses.

Yes, it's parenthetical.

Good. When you've finished studying how to do this, feel free to ask us about anything that's unclear.

I think In original post, that isn't essential to the meaning. What feeling it is was stated "feeling of happiness".

In the original sentence, the word that is similar in meaning to because. One feels happy because something bad did not happen. Another way to say this is: the fact that something bad did not happen is what one is happy about.

I think that something unpleasant has not happened or has ended is an appositive that-clause. Am I correct?

Possibly, yes, but really—why does it matter what it's called?

Your hapiness that something unpleasant has not happened or has ended. Is it possible?


being sad that/ have the sadness that. Is such thing possible for nominalization of adjectives as in abstract nouns?

To my knowledge, "because" is interchangeable with "that" of adverbial clause.

I have no idea what you're asking, sorry.
