Pronunciation
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]

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]
