Root Explanation

Osteoclast → It is formed from "osteo-" (from Greek "osteon", meaning bone) and "-clast" (from Greek "klastos", meaning broken). The word "osteoclast" refers to a cell that breaks down bone tissue.

Memory Tip

Think of 'bone' ('osteo-') being 'broken down' ('-clast') — that's what an osteoclast does.
