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.
Monogamy (/mÉËnÉÉ¡Émi/ mÉ-NOG-É-mee) is a form of relationship in which an individual has only one partner during his or her lifetime or at any one time (serial monogamy), as compared to polygyny, polyandry, or polyamory. Social monogamy refers to two partners living together, having sex with each other, and cooperating in acquiring basic resources such as shelter, food, and money.
