Pronunciation

Forms

osos m or n (feminine singular osoasă, masculine plural osoși, feminine/neuter plural osoase)[1]

Etymology

It is formed from Romanian os + -os, from os “bone”.[2][3][4] Ciorănescu thinks it may be a learned formation, and notes that Pușcariu took it directly from Late Latin ossuōsus (“bony”).[5][6] Cihac, Scriban and Șăineanu also name the Latin word, and Wiktionary gives both explanations.[7][8][9][1] The Latin adjective is formed on os (“bone”), with the ending of adjectives such as virtuōsus.[1] Pușcariu compares Italian ossoso, French osseux and Spanish ososo.[6] Aromanian usos is the Aromanian form, which Pascu derives from the Latin word.[10][11]

Earliest recorded meaning

Tiktin dates the first record to 1785.[4] MDA2 dates it to Budai-Deleanu's lexicon of about 1818, and the Lexicon de la Buda of 1825 glosses it with Latin osseus and ossuōsus.[3][12]

Semantic evolution

The adjective means both “of bone, relating to bones” and “with large, prominent bones”, and by extension “gaunt, thin”.[2][3] Șincai used it of fruit trees bearing fruit with pips.[4] Anatomy uses it in sistem osos “skeletal system” and țesut osos “bone tissue”.[2][13]
