connubial

Etymology

Dating from the 1650s, it comes from Latin connūbiālis, from connūbium (“marriage, wedlock”) (variants of cōnūbiālis, “pertaining to wedlock”, from cōnūbium, “marriage, wedlock”), from com- (“together”; English com-) and nūbō (“marry, to take as husband”, source of nubile), from Proto-Indo-European *snewbʰ- (“to marry, to wed”).
