Question

Is it correct in the English language to call someone esoteric? If it is how would he/she act?

Answer 1

esoteric is not a clear word to describe someone

it may relate to magic and occult sciences

generally it means something deep, unusual

therefore if to say that someone is unusual, it's necessary to specify in what aspect

if to use esoteric as a synonym of knowledgeable or experienced it's not suitable at all

Answer 2

Yes, that's an English word. It means "deep," or "profound," or "beyond the understanding of an average mind." That person would probably act like a genius, because no one ever really understands what they do.

Answer 3

No.  A person with esoteric tastes is called an esotericist.

How would he/she act?  Like someone who knows secrets?
