connubial

The word "connubial" is a direct borrowing from Latin cōnūbiālis, which itself is derived from cōnūbium, meaning "marriage." The core of the word lies in the Latin verb nūbere, "to marry" (specifically for a woman, as seen in its descendant "nuptial"). The prefix con- intensifies the sense of union, translating literally to "a state of being married together." This etymological construction perfectly mirrors the modern abstract meaning, which pertains exclusively to the state or qualities of matrimony. The term entered English in the mid-17th century, retaining its classical dignity and specific marital focus.
