What does cohabited mean?
Cohabited is the past tense of cohabit, a verb meaning to live together and share a domestic life. Its dominant modern sense refers to an unmarried couple sharing a home in an intimate relationship — a usage that has become routine across Britain and America as cohabitation has grown into one of the most common living arrangements before or instead of marriage. A secondary, more literal sense describes any people, groups, or even species dwelling together in one place, as when several families cohabited in a crowded building. The word carries a formal, legalistic tone: sociologists, demographers, and lawyers use it precisely because it avoids the moral overtones of older expressions like 'living in sin'. In casual conversation, speakers more often say 'living together'. Derived forms include cohabitation, cohabitant, and cohabitee, all built on the same Latin roots meaning 'to dwell together'.
verbPast tense of cohabit: to live together and share a domestic life, typically as an unmarried couple, or (of different groups, species, or ideas) to exist together in the same place.
- (Of two people, especially an unmarried couple) to live together in a sexual relationship while sharing a household.
- (Of people, groups, animals, or things) to exist or dwell together in the same space, sometimes harmoniously.
"They cohabited for five years before marrying in a small civil ceremony."
"The couple cohabited for three years before deciding to marry."
"In that crowded tenement, three families cohabited under a single roof."
For most of English history, living together without marriage was so disreputable it was called 'living in sin' — the neutral legal term 'cohabitation' only became everyday vocabulary in the late 20th century.

Etymology of cohabited
Cohabit derives from Latin cohabitare, formed from the prefix co- ('together') and habitare ('to dwell, inhabit'), a frequentative of habere ('to have, hold'). The verb entered English via post-classical Latin in the early 17th century, initially in legal and ecclesiastical contexts describing people dwelling together. Its cognates include inhabit and habit, both ultimately from the same Latin root habitare.
