Pisiforms

Part of speech: noun

Definitions

1. A small, rounded wrist bone located at the base of the hand that plays a role in the wrist's joint structure
2. Characterizing the carpal bone that articulates with the triangular fibrocartilage and is positioned beneath the pinky

Etymology: The plural "pisiforms" names the small, pea-shaped bones of the wrist's outer row, one on each hand's pisiform position. Its singular, "pisiform", is the form that carries the etymology: it combines the Latin "pisum", meaning "pea", with the suffix "-iform", meaning "having the form of" or "shaped like", as in "cruciform" or "uniform". The bone is therefore named for its shape rather than its function or location.
