bone
A rigid organ that forms part of the skeleton in vertebrates.
Etymology
From Old English bān "bone, tusk," from Proto-Germanic *bainą. The Germanic word has no established PIE etymology — it may be a substrate word or a Germanic innovation. The PIE word for bone was *h₃ost- (Latin os, Greek ostéon), which gives English learned terms like "ossify" and "osteoporosis," but "bone" itself does not descend from this root.
The Journey: (no clear PIE root) → bone

Did You Know?
English has two bone vocabularies: the native Germanic "bone" (of unknown deeper origin) and the PIE-descended Latin/Greek terms used in medicine — "ossify," "osteoporosis," "periosteum." The Germanic word replaced the inherited PIE term entirely.
