Forms

pecar (first-person singular present peco, first-person singular preterite pequei, past participle pecado)[1] Houaiss records pecar and pecque in the 13th century, péca and peccasse in the 14th and pecei in the 15th.[2] Wiktionary lists the old spelling peccar.[1]

Etymology

It is inherited from Latin peccō (“to make a mistake, commit a fault”), written Old Galician-Portuguese pecar and Old Galician-Portuguese peccar in the oldest texts.[2][3][4][1]

The same Latin verb is Galician pecar, Spanish pecar, Catalan pecar, French pécher and Italian peccare.[5][1] Corominas holds that the Spanish verb, like all its Romance cognates, is semi-learned rather than truly inherited, since its stressed forms never diphthongise the /e/.[6]

The Latin verb meant to blunder or to commit a fault, and Christian Latin specialised it for an offence against the law of God.[7][8] Its origin is unclear: Walde–Hofmann and Ernout–Meillet linked it with pēs (“foot”), as if “faulty in the foot”; de Vaan objects that nothing in the meaning refers to feet, and mentions Leumann's connection with a root Proto-Indo-European *pet- (“to fall”).[9] Wiktionary reconstructs Proto-Italic *petkāō, from *ped- (“to walk, fall, stumble”).[1]

Earliest recorded meaning

The verb is in the Cantigas de Santa Maria: the seventh cantiga prays por que errar / non nos faça, nen peccar, / o demo “so that the devil may not make us err or sin”.[4] A cantiga of Pero Goterrez has todos dizen que Deus nunca pecou “everyone says that God never sinned”.[4]

Semantic evolution

From the start the verb meant to sin, and it soon covered any fault: Barbosa (1611) glosses it with Latin pecco and delinquo, and quotes Cicero on the difference between the two.[10] With contra it means to offend against a rule, and with por to be faulty through some excess or lack: the old Caldas Aulete quotes Herculano on a zeal que só pecava por excessivo “whose only fault was excess”.[11][2] The proverb é melhor pecar por excesso do que por falta “better to err by excess than by lack” uses this sense.[1]

Timeline

  • 13th century, second half – peccar in the Cantigas de Santa Maria.[4][2]
  • 14th century – the forms péca and peccasse.[2]
  • c. 1430 – pecar in the Horto do Esposo (copied 1390–1437).[12]
  • 1611 – Barbosa glosses the verb as Latin pecco and delinquo.[10]

Meanings

Verb

  1. To sin; to break a religious law or the commandments of the Church.[2][13][1]
  2. To commit any fault or offence; with contra, to offend against: pecar contra a gramática.[2][13][14]
  3. With em, to fall into, incur (an error or defect).[2][13]
  4. With por, to be faulty, open to criticism; to fall short: O livro peca pela extensão.[2][14]

Usage notes

Houaiss, Aurélio and the DLP enter a second verb pecar, formed from peco and the suffix -ar, meaning “to wither, fail to thrive; to become stupid”, first recorded in 1540 in João de Barros.[2][13][14] Morais quotes it from Barros: a fruit vem a pecar from too much growth.[15] The REW, by contrast, derives the adjective peco “spoilt” itself from the Latin verb.[5]
