Monogamy (/məˈnɒɡəmi/ mə-NOG-ə-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. The term is also applied to the social behavior of some animals, referring to the state of having only one mate at any one time.
