Pronunciation

  • IPA: adjective UK /ˈpɜː.fɪkt/, US /ˈpɝː.fɪkt/; verb UK /pəˈfekt/, US /pɚˈfekt/[1]

Etymology

It is inherited from Middle English parfit (“flawless, ideal”),[2][3][4] borrowed from Old French parfit (“finished, completed, ready”) (modern parfait),[2][3][4] from Latin perfectus (“completed, excellent, accomplished”),[2][3][5] the past participle of perficere (“to accomplish, finish, complete”),[2][3][6] formed from per- (“completely”) and facere (“to make, do”).[2][5][7] Etymonline traces facere to Proto-Indo-European *dhe- (“to set, put”).[2][5] The spelling perfect, a classical correction after the Latin, dates from the 15th century.[2][7][4] It is related to fact, affect, effect and parfait.[8][9]

Earliest recorded meaning

Fully formed, faultless: about 1290 in the form parfijt,[10] or about 1300;[3][2] Barnhart notes the surname Parfet in 1196.[3]

Semantic evolution

Hoad dates “thoroughly versed or trained” and “in a complete state” to the 13th century, and “faultless, accurate” to the 14th.[7] Of a legal act, “duly completed”, it is from about 1330.[10] “Complete, full, lacking in no way” is from the late 14th century,[2] and the noun “perfection” from the same time.[2] In arithmetic, a perfect number is from the 15th century, and “unqualified, utter” from the 16th.[7] The intensive use, as in a perfect stranger, comes from the notion of completeness.[2] The grammatical sense, of a tense describing a completed action, is from about 1500,[2] and the noun the perfect from 1841.[11] The verb meant “to bring to full development” from the late 14th century,[2] and “to make perfect or faultless” from about 1449.[10]

The American Heritage Dictionary notes that perfect has often been called an absolute term that cannot be qualified, but that more perfect has reputable precedents, most notably in the preamble to the US Constitution.[12] It compares perfect with consummate, faultless, flawless and impeccable.[12] In Scotland and the north, perfect meant “thorough, utter”.[13]
