adulter m (genitive adulterī); second declension[1]
Etymology
It is perhaps a back-formation from adulterō “to commit adultery, falsify”, from ad- and alter “other”.[2][1][3] Festus explained it as one who goes to another man's wife or another woman's husband.[4]
Earliest recorded meaning
Köbler's first source is Plautus, whom he dates c. 250–184 BC.[5]
Semantic evolution
As a noun it meant an illicit lover, adulterer, as in Cicero, with the feminine adultera, and Virgil and Horace call Paris and Helen adulter and adultera.[2][6] As an adjective it meant adulterous, unchaste, as Horace's hair curled like a lover's and Ovid's adulterous thoughts, and of things impure, adulterated, cross-bred or debased, with adultera clāvis “a skeleton key”.[2][4]
In Medieval Latin it meant spurious, illegitimate, and unauthorized.[7][8] It survives in French adultère and Spanish adúltero.[1] English adultery came about 1300 through Old French avouterie, from avoutre “adulterer”.[3]
