The related word "matrimony" derives from the Old French word matremoine, which appears around 1300 CE and ultimately derives from Latin mātrimōnium, which combines the two concepts: mater meaning "mother" and the suffix -monium signifying "action, state, or condition".
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 forced Gough to disregard sexual access as a key element of marriage and to define it in terms of legitimacy of offspring alone: marriage is "a relationship established between a woman and one or more other persons, which provides a child born to the woman under circumstances not prohibited by the rules of relationship, is accorded full birth-status rights common to normal members of his society or social stratum." Economic anthropologist Duran Bell has criticized the legitimacy-based definition on the basis that some societies do not require marriage for legitimacy.
He argued that a legitimacy-based definition of marriage is circular in societies where illegitimacy has no other legal or social implications for a child other than the mother being unmarried.
Marriage, also called matrimony or wedlock, is a socially or ritually recognised union between spouses that establishes rights and obligations between those spouses, as well as between them and any resulting biological or adopted children and affinity (in-laws and other family through marriage).
The definition of marriage varies around the world not only between cultures and between religions, but also throughout the history of any given culture and religion, evolving to both expand and constrict in who and what is encompassed, but typically it is principally an institution in which interpersonal relationships, usually sexual, are acknowledged or sanctioned.
Some countries do not recognize locally performed religious marriage on its own, and require a separate civil marriage for official purposes.
Conversely, civil marriage does not exist in some countries governed by a religious legal system, such as Saudi Arabia, where marriages contracted abroad might not be recognized if they were contracted contrary to Saudi interpretations of Islamic religious law.
Civil marriage recognizes and creates the rights and obligations intrinsic to matrimony before the state.
When a marriage is performed with religious content under the auspices of a religious institution it is a religious marriage.
Historically, in most cultures, married women had very few rights of their own, being considered, along with the family's children, the property of the husband; as such, they could not own or inherit property, or represent themselves legally (see for example coverture).
