The Good Word doctor used this word today and it occurred to me that I may not have understood the context. The etymology has a distinguished Greek and French history. I looked for the PIE root, which means....to look, see.
This word in English means, relating to meaning in language or logic.

I suspect it is misused currently.

Oh, dear! If you deny "semantic" the meaning "meaning", you've just thrown a massive monkey wrench into the studies of linguistics, logic, and philosophy!
