Forms

peito m (plural peitos)[1] Houaiss records pecto and peytos in the 14th century.[2]

Etymology

It is inherited from Latin pectus (“chest, breast”), written Old Galician-Portuguese peito in the oldest texts.[2][3][1] Nascentes and Aurélio derive the singular from an old plural Old Galician-Portuguese peitos, taken from the Latin neuter and used for both the breasts of a woman and the chest of a man.[4][5] The plural survives in some set phrases.[4] The short Latin /e/ gave closed /e/ here under the influence of the following semivowel.[6]

The same Latin word is Galician peito, Spanish pecho, Catalan pit, Old French piz, Italian petto and Romanian piept.[7][1] De Vaan reconstructs Proto-Italic *pektos- and finds a likely cognate in Old Irish ucht (“breast”), if it comes from an earlier form with /e/; the PIE origin is uncertain.[8][1]

Earliest recorded meaning

Lorenzo's chronology gives the Cantigas de Santa Maria as the first record: the Virgin is she who carried God and de seu peito / mamentou “suckled him at her breast”, and an old woman is made to strike herself no peito.[9] The plural peitos is the bared breast, and de peitos means “face down”.[9] So the first senses are both the breast that suckles and the chest.[9]

Semantic evolution

Bluteau (1712) describes the chest anatomically, and his book of synonyms gives peito for heart, love, affection and will.[10][11] Morais (1789) adds peitos for a woman's breasts, the hidden thoughts, the mind and courage.[12]

The modern dictionaries add the lungs and breathing organs, the front of a shirt, and the breast meat of cattle and fowl.[2][5] In Brazil it also names the breaststroke.[1] The word passed into Guinea-Bissau Creole as pitu.[1]

Usage notes

Houaiss records a separate archaic noun peito “tax, tribute, fine”, a popular form of Latin pactum “agreement” and a synonym of peita; it appears as peito in a Latin charter of 1084 and as peitu in 1121.[2][1] A cantiga says that the king has forbidden que juiz non filhe peito “that a judge take payment”.[18]

Nascentes notes the old plural in meter a faca aos peitos.[4] Fixed phrases: tomar a peito “to take to heart”, peito a peito “face to face”, abrir o peito “to open one's heart”.[2][17][1]
