Morphology

os + ischii

The segment 'os' clearly signals 'bone', so a learner who knows both constituents could infer that this is a bone-related term. However, 'ischii' is a specialized Latin anatomical form (not a common English word) and does not transparently indicate the precise lower/back hip location to a B1 learner, so the meaning is only partially recoverable from the parts.

Etymology

Os ischii comes from two old words: os meaning 'bone' and ischii meaning 'hip' or 'sit bone'. So the name literally says 'hip bone' and is used for the lower, back part of the hip.
