Common collocations

• hip socket Noun + noun

From Middle English socket and Anglo-Norman soket, originally 'a spearhead,' a diminutive of Old French soc ('ploughshare'). The shape-based meaning broadened to a hollow or fitting that receives another part. Electrical, anatomical, and computing senses all extend that central idea of a receiving point.
