Hypergamy (colloquially referred to as marrying up) is a term used in social science for the act or practice of a person marrying another of higher caste or social status than themselves. The antonym hypogamy refers to the inverse: marrying a person of lower social class or status.
Polygamy (from Late Greek ÏÎ¿Î»ÏÎ³Î±Î¼Î¯Î±, polygamÃ­a, state of marriage to many spouses)[1][2][3][4] is the practice of marrying multiple spouses. When a man is married to more than one wife at a time, it is called polygyny. When a woman is married to more than one husband at a time, it is called polyandry.
