Etymology

It is inherited from Middle English innocent, borrowed from Old French innocent and directly from Latin innocēns (“not guilty, harmless”),[2][3][4] from in- “not” and nocēns, present participle of nocēre “to harm”,[2][3][5] from Proto-Indo-European *nek- (“death”).[2] It is related to noxious, innocuous, nuisance and obnoxious.[5][3]

Earliest recorded meaning

Doing no evil, free from sin or guilt: before 1340 in the OED, 1340 in the Ayenbite of Inwyt in Barnhart.[6][3] The noun, a person free from sin, especially a young child, is from about 1200 in Etymonline.[2]

Semantic evolution

Not guilty of a particular crime is from 1382 in the OED, the late 14th century in Etymonline,[6][2] and childlike, simple or artless also from 1382 (about 1385 in Chaucer's Troilus in Barnhart).[6][3] Lacking intelligence, half-witted, is from 1548, a sense kept in dialect.[6][7] Of things, harmless, is from 1662.[6][8] The humorous “free from, devoid of”, as in innocent of grammar, is from 1706.[6][2] The Holy Innocents, the children killed by Herod, are from the early 14th century.[2] Indo-European words for “innocent” are generally negative forms of the word for “guilty”.[2]
