Forms

cometer (first-person singular present cometo, first-person singular preterite cometi, past participle cometido)[1] Houaiss records commeter in the 15th century, and Bluteau heads the word cometer, ou commeter, ou cometter.[2][3]

Etymology

It is inherited from Latin committō (“to join; to entrust; to commit”), written Old Galician-Portuguese cometer in the oldest texts.[2][4][1] Nascentes thinks it came down by a semi-learned route.[5]

The same Latin verb is Spanish cometer, Catalan cometre, Italian commettere and French commettre; the REW records a reflexive sense “to dare” for the Latin verb.[6][7] The Latin verb is formed from con- and mittō (“to send”).[8][1]

Earliest recorded meaning

Houaiss and Cunha date the verb to the 13th century.[2][4] In the cantigas it means “to attack”, “to challenge” and “to undertake”: com'ousastes tal cousa cometer “how did you dare to undertake such a thing”, in an exchange between Bernal de Bonaval and Abril Peres.[9][10] The Crónica Troiana uses it for charging the enemy and for setting about a task.[11]

Semantic evolution

The Cancioneiro da Ajuda already has the modern “to commit”, of folly, beside the senses “to attack, undertake, begin”.[11] Bluteau gives both cometer hum crime and cometer grandes emprezas “to undertake great enterprises”, and Folqman the sense “to entrust a commission to someone”.[3][12]

In modern Portuguese the verb is used mostly of wrong acts: a crime, an error, a sin.[2][13][14] The senses “entrust” and “propose, offer” are still recorded, the second also in the dialects of Portugal, where the verb is said of potatoes beginning to sprout as well.[2][14][15] Houaiss records a joking use, “to perpetrate” a few sonnets.[2]

Timeline

  • 1200s – first records, in the senses “attack, challenge, undertake”.[2][9]
  • c. 1430 – the Horto do Esposo (copied 1390–1437) uses the verb.[16]
  • 1400s – the spelling commeter, and the noun cometimento.[2][4]
  • 1569 – Cardoso's dictionary translates it with Latin committo and admitto.[17]
  • 1500s – first record of acometer.[4]
  • 1712–1728 – Bluteau: cometer hum crime.[3]
  • 1755 – Folqman: “to entrust a commission”.[12]
