semantic??

[I want to learn]

hello
can anyone explain to me what do we mean by semantic, please??

[Kraken]

I'm not sure of what to answer, because it seems too obvious a question. Anyway, the dictionary states:

semantic
adj. pertaining to semantics, of the study of the meaning and use of words and phrases

Is there anything I missed in your question?

It refers to what it means.

You may be told your sentence is correct in terms of grammar, but odd or incorrect or meaningless in terms of semanitcs.

A famous example is "Colorless green ideas sleep furiously."

Grammatically, all the parts of speech are in the right place, but together it just has no meaning.

Semantic relates to the meaning of a phrase, as opposed to its formal construction.
Chomsky's famous sentence "Colorless green ideas sleep furiously" is syntactically correct, but semantically it's nonsense.
If you consider semantics a part of grammar, the sentence is not grammatical. But it has all the right parts of speech in the right place.
<adjective><adjective><noun><verb><adverb>.
On the other hand, many people would consider the following wrong syntactically:
"Don't nobody tell me nothing around here!" But the mean (hopefully) is clear, so it's semantically valid.

Wow. It's amazing when great minds think alike -- and simultaneously!

Semantic
Relating to meaning, especially of words.

Example
Max: I bought a hat.
Sam: You mean you bought a cap.
Max: Semantics!

Yes
I was going to think up another sentence, but I was too lazy!
Sometimes, I wish Chomsky had never said that.
