Root Explanation

Crinoid → It is formed from "krinon" (κρίνον) (meaning lily) and "eidos" (εἶδος) (meaning form or shape). The word "crinoid" refers to the lily-like shape of these marine animals, resembling a flower in appearance.

Memory Tip

Imagine a flower ('krinon') with a specific shape ('eidos') — that's why crinoids are named for their lily-like form.
