Pronunciation

Forms

yegua f (plural yeguas, masculine caballo, masculine plural caballos)[1] The oldest records have egua (949) and yegua (1170); Old Spanish texts also write iegua and eguas.[2][3] Leonese charters of the 13th century still write egua.[4]

Etymology

It is inherited from Old Spanish yegua, inherited from Latin equa (“mare”), the feminine of equus (“horse”).[2][5][6][1] The feminine survived in all the Romance languages or their dialects, while the masculine was replaced everywhere by caballus, whence caballo.[2][7] Cabrera in 1837 already explained the initial sound of the word as a diphthong that grew out of the first vowel of the older form.[8]

The same Latin word is Portuguese égua, Galician egua, Aragonese yeugua, Catalan egua or euga, Occitan èga and Romanian iapă.[9][10][11]

The Latin word for “horse” continues Proto-Italic *ekwos, from Proto-Indo-European *h₁éḱwos (“horse”), seen also in Ancient Greek ἵππος (híppos).[1][12]

Earliest recorded meaning

Corominas finds egua in a charter of 949 and yegua in one of 1170, both from Oelschläger's list.[2][5] The sense was the female horse from the start: the Fuero de Zorita de los Canes (1218–c. 1250) fines whoever puts another man's stallion to his mare without the owner's knowledge: tod aquel que cauallo ageno asu yegua, el sennor del cauallo no sabiente, echare.[4]

Semantic evolution

The word belongs to Castilian of every period.[2] Alfonso X's laws list the tithe paid on mares beside that on cows and sheep.[13] The Diccionario de Autoridades (1739) quotes the Quijote and the proverb Donde hay yeguas, potros nacen.[14] The Academy's 1884 edition explains the proverb as a warning not to wonder at what comes naturally, and records yegua caponera, the mare that leads a herd of mules or horses, and the phrase andar con uno a mátame la yegua, matarte he el potro, to quarrel stubbornly and needlessly.[15]

In Spanish America the word has many figurative uses: a coarse woman in Cuba and Uruguay, a cigarette butt in Central America, a stupid person in Central America and Puerto Rico, and in Chile an adjective meaning “huge”.[6][16] In Mexico it is a name for several large beans.[17] It was borrowed into Tagalog yegwa and into several languages of Mexico and Guatemala.[1]
