means A small, hook-shaped carpal bone on the pinky side of the wrist, named for the curved hook of bone that projects from its surface.

from From Latin 'hamatus,' meaning 'hooked' or 'shaped like a hook,' from 'hamus,' a hook — the same root that gives us 'hamulus' in anatomy for other small hook-like projections. The bone earned the name plainly, by looking like what it was called: it carries a bony hook (the hamulus) jutting from its palm-side surface, which is exactly the part that tends to fracture when a bat or club handle rams into it.
