I just learned about something called an osteoma in my biology class.

Root Explanation

Osteoma is formed from "osteon" (from Greek "ὀστέον", meaning bone) and "-oma" (from Greek "ὄμα", meaning tumor or swelling). The word osteoma refers to a tumor or growth that originates in the bone.

Memory Tip

Think of 'osteon' meaning bone, and '-oma' indicating a tumor — so an osteoma is a tumor that forms in the bone.
