What term refers to a male-female couple living together without marriage?

Cohabitation refers to a male-female couple living together in a romantic relationship without the legal formalities of marriage. This term captures the essence of both individuals sharing a domestic space and typically suggests a significant emotional and personal commitment between them, even in the absence of a marital contract.

Cohabitation has become increasingly common in contemporary society and can involve various arrangements, such as long-term partnerships or shorter-term living arrangements. The term distinguishes this type of relationship from traditional marriage and highlights the evolving nature of intimate relationships in modern culture.

The other terms do not adequately convey the specific arrangement of living together as a couple without being married. For example, "partnership" can refer to a wide variety of collaborations, not necessarily romantic or living arrangements. "Coexistence" generally implies simply existing in the same spaces or communities without the relational dynamics present in cohabitation. Lastly, "composition" is more related to the makeup or structure of something rather than a living arrangement or relationship dynamic, making it unrelated to the specific scenario presented.
