Forms
égua f (plural éguas, masculine cavalo, masculine plural cavalos)[1] Old Galician-Portuguese wrote egua, egoa and ega;[2][3][4][5] egoa was usual from the 13th century and the dictionaries head the word so until the 19th.[2][3][4][5] Morais (1813) and Vieira (1871) still refer égua to egoa.[6][7]
Etymology
It is inherited from Latin equa (“mare”), written Old Galician-Portuguese egua and Old Galician-Portuguese egoa in the oldest texts.[8][2][3][1] The Latin word is the feminine of equus (“horse”).[9][10]
The same Latin word is Galician egua, Spanish yegua, Catalan egua, Occitan èga and Romanian iapă.[11][12][1]
The Latin noun goes back to *ekwo- and Proto-Indo-European *h₁eḱ-u- (“horse”), whose cognates include epos and ech.[10]
Earliest recorded meaning
Latin charters of Portugal write the Romance word from the 10th century: Houaiss dates it to 958, after Machado, and the DDGM quotes una egua et uno boue “one mare and one ox” from 985.[8][3] In Galician-Portuguese the Cantigas de Santa Maria have en sa egua veira “on her piebald mare”, and Lopo Lias begins aqueste cantar da egoa “this song of the mare”.[3]
Semantic evolution
The sense “female of the horse” has not changed.[8][2] Figuratively the word is applied to a dull or coarse person, and in Brazil it is a vulgar term for a prostitute.[8][13][14] Aurélio notes that in the north-east the word itself was felt as more or less obscene, so that besta and other names were used for the animal.[8][13][14] In Pará and Maranhão égua! is an interjection of surprise or admiration.[8][15] The word passed into Kabuverdianu as égua and Macanese as égu.[1]
