What term describes the practice of being married to only one person at a time?

The practice of being married to only one person at a time is known as monogamy. Monogamy refers specifically to a marital arrangement where an individual has one spouse during their lifetime or at any given time. This concept is prevalent in many cultures and societies around the world, including Canada, and is often seen as the traditional or standard form of marriage.

In contrast, polygamy involves having multiple spouses simultaneously, which is not the focal point of this question. Patriarchy refers to a social system in which men hold primary power, and feminism pertains to the advocacy of women's rights and equality. Neither of these terms relates to the marital structure described by monogamy. By understanding these distinctions, it becomes clear that monogamy is the correct term to describe being married to only one person at a time.
