os n (plural oase)[1]

Etymology

It is inherited from Latin ossum (“bone”), the popular form of Classical Latin os (“bone”).[2][3][4][5][1] The Latin word goes back to Proto-Indo-European *h₃ésth₁ (“bone”).[1]

The word survives in all four branches: Aromanian os, Megleno-Romanian uos and Istro-Romanian os.[2][6][7][8][9] Its Romance cognates include Italian osso, French os, Catalan os, Spanish hueso and Portuguese osso.[2][4] Pușcariu compares the plural ⟨oase⟩ “the bones of a body” with ossa.[3]

Earliest recorded meaning

Tiktin's first record is a charter of 1437.[10] In Romanian texts the word appears in the Psaltirea Hurmuzaki of the early 16th century, where the plural oasele “my bones” occurs eight times, as in Psalm 6:2.[11][5]

Semantic evolution

Besides the bone itself the old language used the word for the body and for kinship: Ureche says of a claimant that he was „de osul lui Ștefan Vodă” “of Prince Stephen's bone”, his own son.[10] The sense “family, lineage” is still listed by the dictionaries, as is the plural for a dead person's remains.[2][12] In Oltenia and the Banat the word also means the stone of a fruit.[2]

Many idioms use it: a fi numai piele și oase “to be skin and bone”, a-i ajunge cuțitul la os “to be at the end of one's patience”, and un os de ros “a bone to gnaw”, a profit thrown to someone.[12][10]
