Pronunciation
Forms
terceiro (feminine terceira, masculine plural terceiros, feminine plural terceiras)[1]
Etymology
It is inherited from Latin tertiārius (“containing a third; third”), written Old Galician-Portuguese terçeiro in the oldest texts.[2][3][4][5][1] Nascentes notes that it took the place of tertius (“third”), from which the Latin adjective is formed with the suffix -ārius.[4][6][1] The learned doublet is terciário.[1]
The same Latin word is Galician terceiro, Spanish tercero, Catalan tercer, Old Occitan tersier and Old French tercier.[7][1] The shortened form Old Galician-Portuguese tercer of the medieval texts matches the Catalan word.[8][8][2]
Earliest recorded meaning
Houaiss's first records are of the 13th century, as tercer and terceyro.[2] The Cantigas de Santa Maria have terçeira and tercer: duas partes leixa e di ben a terçeira “leave out two parts and tell the third well”, and a tercer dia ressocitó-o “on the third day he raised him to life”.[8] These records already have the ordinal sense.[8]
Semantic evolution
Cardoso (1569) and Pereira (1697) gloss terceiro only with Latin sequester and internuntius, the go-between whom two parties trust.[9][10] Morais (1789) gives a mediator, a broker and, figuratively, a procurer; his edition of 1813 adds the ordinal, the third person of the verb and the Ordem Terceira, the lay order of Saint Francis.[11][12] Nascentes explains that it was the third order he founded, after the Friars Minor and the Poor Clares.[4] In law terceiro is a third party to a contract or suit; in Brazil it was a sharecropper owing a third of the crop, and recently a worker supplied by an outside firm.[2][13]
