Cohabitate vs. Cohabit — What's the Difference?

Difference Between Cohabitate and Cohabit


Key Differences

Cohabitate often appears in discussions around legal and social contexts, emphasizing the aspect of living together without being married. On the other hand, cohabit is a more general term that simply means to live together in the same household, regardless of the nature of the relationship or the legalities involved.
Both terms imply a shared living arrangement, but cohabitate sometimes carries a connotation of coexisting in a domestic partnership that is not sanctioned by marriage. Whereas, cohabit is more neutral, indicating the act of living together without implying any specific legal or social status.
The choice between cohabitate and cohabit can depend on the desired specificity or formality of language. Cohabitate might be chosen for discussions focusing on the legal or social implications of living together without marriage, while cohabit is often used in broader contexts where the specifics of the relationship are not the focus.
In legal documents or discussions about domestic law, "cohabitate" can be preferred to specifically address situations where individuals live together as a couple without being married. Conversely, "cohabit" is more likely to be used in general discussions or studies about living arrangements, without necessarily implying a romantic relationship.
Despite their nuances, in everyday language, the distinction between cohabitate and cohabit is often blurred, and the terms are used interchangeably by many. The choice of term may vary by region, preference, or the context in which it is being used.
