where did the word nimrod come from?

where did the word nimrod come from? I can’t immagine it being derived over thousands of years from a given culture’s language, but perhaps I’m wrong.

Thanks.

Etymology: Hebrew NimrOdh ( from www.m-w.com )

What is it that you can’t imagine exactly?

It’s from the Bible:

Genesis 10:8-10

A much better etymology:

Daniel

Maybe **saluki_fan ** is asking how Nimrod, the ancient hunter, became synonymous with idiot.

According to the word detective, it’s all because of Bugs Bunny.

People seem to use it as an insult. Why?
