What does cohabiting mean?
Cohabiting is the present participle of the verb 'cohabit', meaning to live together and share a household. Its dominant modern use describes an unmarried couple who live together in an intimate relationship without being married — a usage central to sociology, law, and everyday discussion of modern relationships, where cohabitation has become a common alternative or precursor to marriage. The word can also apply more neutrally to any individuals, or even animals, occupying the same dwelling. Derived from Latin roots meaning 'to dwell together' (com- 'together' + habitare 'to dwell'), it entered English in the early 16th century. Cohabiting carries a formal, neutral tone: it avoids assumptions about marital status and is preferred in statistics, legal documents, and research. Related forms include cohabitation, cohabitant, and cohabitee.

Etymology of cohabiting
Cohabiting derives from the verb 'cohabit', which English borrowed from French 'cohabiter', itself from Late Latin 'cohabitare', formed from Latin 'com-' ('together') and 'habitare' ('to dwell'), a frequentative of 'habere' ('to have, hold'). The verb was first attested in English in the early 16th century. It shares its root with words such as 'inhabit', 'habitat', and 'habitable', all tracing back to the same Latin stem for dwelling.
