The Full Story
Proto-Germanicc. 500 BCE – 1 CEwell-attested
The English word 'rib' descends from Proto-Germanic *rebją, supported by cognates across every major Germanic branch: Old High German rippi, Old Saxon ribbi, Old Frisian ribbe, Old Norse rif. The proto-form traces to Proto-Indo-European *rebh- (also *rebh₂-), carrying senses of 'to roof over', 'to cover', or 'to arch' — a metaphor of the ribcage as a vaultedcovering over the vital organs. Cognates outside Germanic include Old Church Slavonic rebro ('rib') and possibly Greek

When Gothic architectsneeded a word for the curved stone arches bearing the weight of a vaulted ceiling, they borrowed it from the body: a rib in a cathedral is the same word as the rib in your chest, extended by the same visual logic that the Anglo-Saxon poet used when he wrote about Adam's rib in the Old English Genesis. One word, three registers — anatomy, scripture, and stone — all from Proto-Germanic *rebją.
narrative: God forms Eve from one of Adam's ribs (OE: 'God genam ane of his ribbe', Genesis 2:21–22), giving the term theological weight throughout the Anglo-Saxon period. The medical corpus — including Bald's Leechbook and herbal glossaries — uses ribb in anatomical contexts, placing the word in both sacred and practical registers. Its unbroken attestation from Old English to Modern English, with minimal phonological shift, confirms its entrenchment in the core Germanic lexicon. Key roots: *rebh- (Proto-Indo-European: "to roof over, to cover, to arch"), *rebją (Proto-Germanic: "rib, curved chest bone; possibly also ridge or arched structure"), ribb (Old English: "rib (anatomical); attested in medical glossaries and Biblical translation").
