matrimonial

Anything matrimonial has something to do with marriage or married people. A formal way to say “wedding,” for example, would be “matrimonial event.”

Marriage is a matrimonial agreement or bond, and the house a newly wed couple moves into can be called a matrimonial home. Matrimonial law governs the rules of marriage — like the license that declares two people legally married, or the age a person must be, legally, to get married. Originally, matrimonial was a noun meaning “a marriage,” and then “a classified ad posted by someone seeking a spouse.”
