Idonyms are words that are eponyms that you would not necessarily think are eponyms.

I derived the term “idonym” from “idoneous” and I do not mind so much about combining Latin and Greek. I also create other words.

Not to be confused with Aptronym.

Not to be confused with Idionymon.

Not to be confused with Idiom.

I add to this list as I fancy. Contributions are welcome.

  • variant of common word with a reason

Cotten picking (you would think it was Cotton picking)

dumpster

  • name-derived term

Debian, or the French ‘poubelle’ in the comments, which have become genericized to the point where most of its users don’t know the derivation
