Etymology: Osteophyte is a modern medical coinage built from two Greek roots: "osteon", meaning "bone", and "phyton", meaning "plant" or "growth". The Greek element "phyton" is the source of the English "-phyte" ending, which also appears in words like "epiphyte" and "bryophyte". Medicine borrowed the same pattern to describe something that behaves like a plant sprouting from bone. The word reached English from French "ostéophyte", so it is a learned term rather than one that came into everyday speech. Its meaning is precise: a bony outgrowth, usually a spur-like projection that forms at the edges of a joint. Such growths are a common feature of osteoarthritis, where they develop as the body tries to repair cartilage and bone under strain.
