adulterium n (genitive adulteriī or adulterī); second declension[1]
Etymology
It is from Latin adulter (“adulterer”) + -ium.[2][1] De Vaan lists adulter “clandestine lover” among the derivatives of alius “other”, as a compound of ad and alter.[3][1] The OLD suggests adulter may be a back-formation from adulterāre.[2]
Earliest recorded meaning
Plautus describes a man “full of perjury and adultery”.[2] Köbler dates Plautus c. 250–184 BC.[4]
Semantic evolution
It meant adultery, as in Cato's speech about catching one's wife in adultery and Cicero's man caught in the act.[2] Quintilian defines it as lying with another man's wife.[5] In Manilius and Pliny it also meant the mixing of different ingredients or the grafting of trees.[2]
Isidore says it got its name because it defiles another's bed.[6] The Vulgate uses it of the woman taken in adultery.[5] English adultery came from it through Old French around 1300.[7]
