" connubial "

[Adjective]  | "con*nu*bi*al" | \ kə-ˈnü-bē-əl \

1: of or relating to the married state : conjugal

Origin: circa 1656 ;

 Borrowed from Latin cōnūbiālis, from cōnūbium, cōnubium "intermarriage between two groups, marriage, the right to marry," from con- {see: |con-|com-} + nūbere "[of a woman] get married" + -ium, suffix of deverbal compounds {mat|nubile|};

  * Note : The length in the initial syllable of cōnūbium has been explained as reduction of a cluster *-nsn-, which assumes that the etymon of nūbere began with *s-; see: note at {nubile|nubile}.;
