Etymology

It is Old Galician-Portuguese matar in the oldest texts, a verb whose origin has long been disputed.[2][3] Houaiss gives Corominas's view first: it is inherited from Vulgar Latin *mattō (“to strike, knock down”).[2] Corominas derives this verb from Late Latin mattus (“stupefied, dull”), an adjective recorded from imperial times whose own origin is uncertain; the verb is typical of the three Ibero-Romance languages, and in the Middle Ages it also meant “to wound”.[4][5] Aurélio follows the same derivation.[6]

Machado, as Houaiss reports, takes the Vulgar Latin verb to be a popular development of Latin mactō (“to honour; to sacrifice; to kill”).[2] Wiktionary and the DLP also start from the Latin verb, but Wiktionary notes that the change of -ct- to -t- would be irregular, and so allows a derivation from, or an influence of, the Latin adjective.[1][7] Nascentes names Diez, Cornu and Adolfo Coelho on this side.[8]

Carolina Michaëlis de Vasconcelos, João Ribeiro, Meyer-Lübke and Lokotsch instead traced the verb to Arabic مَاتَ (māta, “he died”), the word that ends the chess call xeque-mate, “the king is dead”.[8][9] Meyer-Lübke and Lokotsch held the Latin source to be impossible for its sound.[8][9] Corominas rejects this: a word in general use from the 10th century for so basic a notion is unlikely to come from an aristocratic game, and the Romance forms agree closely with the Vulgar Latin adjective.[4] Cunha leaves the origin unknown.[10]

The same verb is Galician matar, Spanish matar and Catalan matar; in Spain it is recorded from the second half of the 10th century, in the Glosses of Silos.[4][11]

Earliest recorded meaning

Houaiss dates the verb to the 13th century, from the slips of Cunha's index of medieval Portuguese.[2][10] In the cantigas it means “to kill” and, figuratively, “to afflict, to move deeply”, and the pronominal matar-se is “to kill oneself”.[12] The Crónica Troiana uses it of knights who strike each other to kill or wound.[9]

Semantic evolution

The figurative senses are old: the cantigas d'amigo use the verb for being overcome with joy or emotion, and an escarnho for being driven to despair.[9] Morais in 1813 adds “to put out” (a candle, a fire), “to make plants wither” and “to pay off” a debt.[13] From the idea of ending a need came matar a fome and matar a sede, “to still one's hunger, quench one's thirst”, which Folqman already has in 1755.[14] Later senses are “to tire out, wear down”, “to ruin” and “to solve” a riddle.[15][16]

Brazilian Portuguese uses it for “to skip” a class or work and “to finish off” a drink or a supply; in billiards it is “to pocket” a ball.[1][16] In Angola it can mean “to sell at a speculative price, outside the legal channels”.[17] In north-eastern Brazil a widow may say that she “killed” a husband she outlived.[18]

Timeline

  • 13th century – first records, in the cantigas.[2][12]
  • 1350 – matar in the Trasladação de S. Nicolau, in a 14th-century witness.[19]
  • 1569 – Cardoso renders it with Latin neco.[20]
  • 1712–1728 – Bluteau derives it from a Hebrew mat “dead”.[21]
  • 1755 – Folqman lists matar a fome and matar a sede.[14]
  • 1813 – Morais records the senses “to put out” and “to pay off”.[13]
  • 1871–1874 – Vieira derives it from Latin mactare.[22]

Usage notes

Houaiss records two minor verbs of the same spelling: an informal matar “to spy on”, from French mater, and a needlework term “to close two loops in one stitch”, which he derives, after the Grande Dicionário da Língua Portuguesa, from mate with the suffix -ar.[2] The DLP has the needlework verb as well.[7]

Matar o bicho is to take a drink of spirits in the morning on an empty stomach.[17]
