Definitions

1. Describing an animal whose pelvis is broad and flattened, with the pubic and ischial bones lying nearly parallel

Etymology: "Platypelvic" is a technical coinage built from two parts: "platy-", from Greek "platys" meaning "broad" or "flat", and "pelvic", from Latin "pelvis" meaning "basin". Put together, the word describes a pelvis that is flattened or broadened in shape, the kind of structure a physician or anatomist would need to name precisely when describing a bone's form. The pattern is familiar from other scientific vocabulary, where "platy-" appears in words such as "platyrrhine" (broad-nosed) and "platypus" (flat-footed). The combining form lets anatomists attach a single descriptive element to an existing anatomical term, so the word is essentially a compact description rather than a story in itself.
