Have you heard about the new study on osteoclastic activity in bones?

No, I haven’t! What did they find out?

Root Explanation
Osteoclastic → It is formed from "osteo-" (from Greek "osteon", meaning bone) and "clastic" (from Greek "klastos", meaning broken). The word "osteoclastic" refers to cells that break down bone tissue.
Memory Tip
Think of 'bone' ('osteo-') being 'broken down' ('clastic') — that's what osteoclastic means.
