cohabiting definition
Cohabitation is an arrangement where two people who are not married live together. Such arrangements have become increasingly common in Western countries during the past few decades, being led by changing social views, especially regarding marriage, gender roles and religion. They often involve a romantic and/or sexually intimate relationship on a long-term or permanent basis. More broadly, the term cohabitation can mean any number of people living together. To cohabit, in a broad sense, means to coexist. The origin of the term comes from the mid 16th century, from the Latin cohabitare, from co- 'together' + habitare 'dwell'.
