Pronunciation

  • Classical: [ˈɔs.se.ʊs][1]
  • Ecclesiastical: [ˈɔs.se.us][1]

Forms

osseus (feminine ossea, neuter osseum); first/second-declension adjective[1]

Etymology

It is from Latin os2 (“bone”) + -eus.[2][1] De Vaan lists it among the derivatives of ⟨os⟩, which goes back to Proto-Italic *ost and Proto-Indo-European *h₃o/est- (“bone”).[3]

Earliest recorded meaning

It is found from Plautus on.[3] In the Cistellaria it describes thin, feverish girlfriends as all bone, the sense of “emaciated”.[2]

Semantic evolution

In the literal sense of “made of bone” the comic poet Atta has a stylus with a bone point,[2][4] Ovid calls a skeleton an ossea forma, and Columella speaks of bone wedges and knives.[2] It was also said of things as hard as bone: Pliny the Elder uses it of the wood of some palms and of the holm oak.[2][5] Juvenal keeps the old sense of “bony, skinny” for a Moor's hand.[2]

English took it in the early 15th century as ossuous and ossous, through a Medieval Latin form, and re-formed it in the 1680s as osseous.[6]
