People (typically men) who are unfaithful in marriage by having a romantic or sexual relationship with someone other than their spouse.
From Old French 'avoutrer,' derived from Latin 'adulterare' (to corrupt, defile). The -er suffix denotes an agent or person who performs the action. The term has been used since medieval times to describe those who violate marriage vows.
Adultery laws were once so serious that they could result in execution or mutilation—in some cultures, adulterers were literally branded with letters. The word itself comes from Latin roots meaning 'to make false or corrupt,' because infidelity was seen as corrupting the purity of marriage.
