Have you seen that new art installation downtown?

Yeah, I walked by it yesterday; it's so amorphous!

Root Explanation
Amorphous is formed from "a-" (meaning without) and "morphē" (meaning form or shape). The word describes something that lacks a definite shape or form.
Memory Tip
Think of 'without' ('a-') a 'form' ('morphē') — that's why amorphous means lacking a definite shape.
