cohabitate
Live together unmarried
Cohabitate means to live together, especially as an unmarried couple in a romantic relationship: They cohabitated for three years before getting married.
The word is a back-formation from cohabitation, though cohabit is the older and more standard verb form.
Both carry slight formality, often appearing in legal or sociological contexts.
