Forms
osso m (plural ossos, metaphonic)[1] Houaiss records the 15th-century spellings osoos, osos and ousso.[2] The plural ossos is metaphonic, with an open stressed vowel.[1]
Etymology
It is inherited from Latin ossum (“bone”), the popular variant of os (“bone”), with the same form in the oldest texts.[2][1][3] De Vaan finds ossum from Accius on, and Corominas notes that it is frequent in Latin from the 4th century and that the Romance languages kept only this form.[4][5] The same Latin word is Galician óso, Spanish hueso, Catalan os, French os, Italian osso, Romanian os and Sardinian ossu.[6][1]
For the classical noun de Vaan reconstructs Proto-Italic *ost and Proto-Indo-European *h₃o/est- (“bone”), with cognates such as Ancient Greek ὀστέον (ostéon) and Hittite haštāi.[4] Wiktionary gives the root as Proto-Indo-European *h₃ésth₁ (“bone”).[1]
Earliest recorded meaning
Lorenzo's chronology antedates Machado's record of 1517 with the Cantigas de Santa Maria: log'os ossos foron ben soldados “at once the bones were well knit”, and non á osso são / na cabeça “there is no sound bone in his head”.[7] The Crónica Troiana has the wound going so deep que lle pareçia o osso “that the bone showed”.[7]
Semantic evolution
In the Cantigas de Santa Maria the plural already means a person's remains, laid in a tomb.[7] Barbosa (1611) lists ossinho, juntas dos ossos “joints” and ossada.[8] Bluteau (1712–1728) describes the skeleton as a building, with the bones of the feet as foundations and the skull as a vault.[9]
Figurative senses are a difficulty or obstacle and, by metaphor, a comfortable job.[2][10][1] In Brazilian slang it also means a mistress, and as an adjective “difficult”, “annoying”, “fearless” or “capable”.[2][10][1] The anatomical term osso sacro “sacrum” renders the Latin name, itself a calque of the Greek “sacred bone”: Houaiss explains it by the ancient custom of offering that part of the victim to the gods.[2]
