The term "marriage of convenience" refers to a situation where two people get married for practical reasons rather than for genuine love or romance. It's a term that has been used throughout history, but there are several other synonyms that can be used to describe this type of arrangement. One such synonym is a "business marriage," which implies that the two parties are entering into the union purely for financial gain. Another synonym is a "strategic marriage," which suggests that the marriage is being used as a means to an end, such as gaining social status or political power. Regardless of the terminology used, a marriage of convenience is typically characterized by a lack of emotional connection between the partners involved.
