Morphology
os + triquetrum
The phrase literally combines Latin 'os' (bone) with 'triquetrum' (the three-sided carpal bone), so a learner who knows both constituents can infer it refers to the triquetrum bone in the wrist. This is a directly compositional, technical naming pattern (common in anatomical terminology), making the meaning accessible to learners familiar with the parts.
Etymology
Os triquetrum comes from Latin words: os meaning 'bone' and triquetrum meaning 'three-cornered'. The name fits the small triangular wrist bone because it is shaped like a three-cornered piece and touches three nearby bones, so the word helps you remember its shape and place.
