Civil marriage recognizes and creates the rights and obligations intrinsic to matrimony before the state.
Over the twentieth century, a growing number of countries and other jurisdictions have lifted bans on and have established legal recognition for interracial marriage, interfaith marriage, and most recently, gender-neutral marriage.
The anthropological handbook Notes and Queries (1951) defined marriage as "a union between a man and a woman such that children born to the woman are the recognized legitimate offspring of both partners." In recognition of a practice by the Nuer people of Sudan allowing women to act as a husband in certain circumstances (the ghost marriage), Kathleen Gough suggested modifying this to "a woman and one or more other persons." In an analysis of marriage among the Nayar, a polyandrous society in India, Gough found that the group lacked a husband role in the conventional sense; that unitary role in the west was divided between a non-resident "social father" of the woman's children, and her lovers who were the actual procreators.
None of these men had legal rights to the woman's child.
This in turn is derived from Old French, marier (to marry), and ultimately Latin, marītāre, meaning to provide with a husband or wife and marītāri meaning to get married.
The adjective marīt-us -a, -um meaning matrimonial or nuptial could also be used in the masculine form as a noun for "husband" and in the feminine form for "wife".
