Pronunciation

Etymology

It is inherited from Middle English deceite, also deseyte and desaite,[2] borrowed from Old French deceite,[2][3][4][5][6] the feminine past participle of deceveir (modern décevoir), used as a noun.[2][5][7][8] The Old French verb is from Latin dēcipiō (“to ensnare, take in, cheat”),[3][9] formed from dē- and capiō (“to take”),[3][9] from Proto-Indo-European *kap- (“to grasp”).[3] The Anglo-Norman noun is recorded from 1275, already for deception, fraud and trickery.[10] Weekley notes that the regular Old French form would have been different, but the vowel was assimilated to the stressed stem of the verb, the source of deceive;[11][2] the OED compares conceit.[2] Old French also spelled it after decepta, and English accordingly had deceipte, although the p was never pronounced.[2] Middle English often had the prefix as dis-, as in disceyte, because the Old French prefix des- was changed back to Latin dis-.[2][5]

Earliest recorded meaning

Trickery, deception, false dealing: about 1300, in Kyng Alisaunder, according to the OED[2] and Etymonline, which glosses it "trickery, treachery, lying".[3] Barnhart finds disceyte probably before 1300, and deceyte about 1325 in Kyng Alisaunder.[5][12]

Semantic evolution

The word has kept its sense of deceiving from the start; what changed was mostly its range of uses.[2] From the early 14th century it also meant the quality of deceiving, deceitfulness, in 1303 in Mannyng's Handlyng Synne,[2][3] and since about 1380, in Wyclif, a single trick or stratagem, with a plural.[2] Etymonline adds the sense "false appearance, illusion" from the mid-14th century.[3] Chaucer used it 12 times and Gower 17 times, for deceit, trickery and illusion.[13] Phrases such as in deceit of and without deceit, "assuredly", were used from 1303 to 1629.[2] A legal sense, deceit as a wrong for which one can sue, is recorded from 1495.[2] The pronunciation also changed: the OED notes that in the 17th century the word usually rhymed with bait, and the narrowing of the vowel to that of seat came later.[2] Johnson (1755) defined it as fraud, a cheat, or any practice by which falsehood passes for truth.[14] A short-lived verb deceit, to forge a document, is recorded in 1484.[2]

Usage notes

Etymonline quotes the Century Dictionary: deceit is a shorter and more forceful word for the quality of deceitfulness, and only more rarely names the act, while deception properly names the act or course of deceiving, and fraud an act of deceit for one's own gain, generally against the law.[3] Dictionary.com likewise groups it with guile, duplicity and fraud as words for practices meant to mislead.[17]
