Serial monogamy is a type of marriage in which each partner has just one spouse at a time but marries a series of partners in succession. This differs from traditional monogamy in which a person has only one spouse for their lifetime. Polyandry refers to a type of marriage in which a woman has multiple husbands at the same time, while polygamy refers to a type of marriage in which a person has multiple spouses at the same time (often used to refer to a man having multiple wives).
