Pronunciation

  • Brazil: /ˈva.kɐ/[1]
  • Portugal: /ˈva.kɐ/[1]
  • Northern, Portugal: /ˈba.kɐ/[1]

Forms

vaca f (plural vacas)[1] Old texts also write uaca and vaqua;[1] Houaiss records uacas in 1392 and vacas in 1393.[2][3]

Etymology

It is inherited from Latin vacca (“cow”), written Old Galician-Portuguese vaca and Old Galician-Portuguese uaca in the oldest texts.[2][4][1]

The same Latin word is Galician vaca, Spanish vaca, Catalan vaca, French vache, Italian vacca and Romanian vacă.[5][1]

The origin of the Latin word is uncertain.[1] It has been compared with Sanskrit वशा (vaśā, “cow”), but de Vaan points out that Latin would then need an o-grade, which does not give /a/ in a closed syllable, so the comparison works only if the Italic form somehow acquired its double consonant.[6][1]

Earliest recorded meaning

Latin charters name cows from the 9th century: vacas numero X in 816, VII uacas in 837.[3] The first Galician-Portuguese records are of the 13th century: in the Cantigas de Santa Maria a woman had lost a cow she loved dearly (hũa vaca perdera que muit' amava).[2][4][3]

Semantic evolution

Medieval texts use the word for the animal, in lists with oxen, sheep and horses.[3] By metonymy it came to mean beef, the meat sold for food.[2][7] Morais in 1813 records vaca de chocalho, the bell cow that leads wild bulls, and its figurative use for a woman who draws others along.[8] Card games gave the sense of a stake put up jointly by several players and played by one, and Brazil a collection of money for a shared expense, also called vaquinha.[2][9] Other Brazilian senses are the 25th group of the jogo do bicho and, in Rio de Janeiro, a fish.[2] The word is also a sexist insult for a woman.[2][1]

Kabuverdianu has báka and Papiamentu baka, both from the Portuguese word.[1]
