What is the term for a marriage structure involving one woman and one man exclusively married to each other?

Monogamy refers to a marriage structure where one woman is exclusively married to one man, and vice versa. This arrangement is characterized by a commitment to a single partner, which is a conventional and widespread practice in many cultures around the world. Monogamous relationships emphasize exclusivity and often include a social expectation of fidelity between partners.

The concept is foundational in many societies and is often associated with various legal, religious, and sociocultural frameworks that promote and uphold the notion of one-to-one partnerships. In contrast, polygamy entails having multiple spouses simultaneously, bigamy specifically refers to being married to two people at the same time, often in a legal context that prohibits such an arrangement, and an open marriage indicates a consensual arrangement where partners may engage in sexual or romantic relationships with others outside the marriage.
