A little etymology for you

WHAT IS THE ORIGIN OF CONNUBIAL?

Connubial “of marriage or wedlock” derives from Latin cōnūbiālis, from cōnūbium“wedding,” plus the adjective-forming suffix -ālis. Cōnūbium, in turn, is a compound of com-“together, with” and nūbere “to wed,” and nūbere (stem nupt-) is the source of marriage-related words such as nubile, nuptial, and prenup. Nūbere is of obscure origin, but one theory is that its original definition was “to cover oneself with a veil,” which would suggest a derivation from nūbēs “cloud.”
