Pronunciation
Forms
rosto m (plural rostos)[1] The medieval texts have both rostro (also rrostro) and rosto.[2][3][4]
Etymology
It is inherited from Latin rōstrum (“beak, snout”), through the medieval form Old Galician-Portuguese rostro, which lost its second /r/ by dissimilation and became Old Galician-Portuguese rosto.[5][4][6][1] The learned rostro, “beak; rostrum”, is a doublet taken from the same Latin word.[7][1]
The Latin noun meant a bird's beak or an animal's snout, and also a ship's ram, the point of a ploughshare and the nozzle of a lamp.[5] Corominas notes that it was used of people only by the most colloquial writers, such as Plautus and Petronius, as a jibe, much as one might say “snout”; the word then went from “mouth” to “face”.[8] Nascentes adds that it displaced Latin vultus (“face”).[9]
The same Latin word is Galician rosto, Spanish rostro and Catalan rostre.[10][11] The Latin word is formed from rōdō (“to gnaw”) with the instrumental suffix -trum, so that it meant first “the thing one gnaws with”.[8][1]
Earliest recorded meaning
A legal text of 1209 printed among the Portugaliae Monumenta Historica lists de ollo, de narizes, de rostro, de mano, de pe “of eye, of nose, of face, of hand, of foot”.[2] The Cantigas de Santa Maria use rostro and rosto for a person's face (o rostr' e a garganta ll'enchara “his face and throat had swollen”).[2][3] A cantiga d'escarnho by Fernand' Esquio still has the older sense, the muzzle of an animal.[2]
Semantic evolution
Lorenzo shows the word moving from “mouth, lip” to “face” early in the Galician-Portuguese texts.[2] From “face” came “expression, look” and “courage to face something”, and the front of a building.[5][12] In printing, rosto is the title page of a book, short for folha de rosto or página de rosto; in numismatics it is the reverse of a medal.[5][13]
Several phrases go back to the early dictionaries: Barbosa in 1611 has fazer bom rosto “to put a good face on it” and dar em rosto “to reproach”.[14] Silva Bastos records rosto as slang for “blood”.[13]
