Cohabit versus Cohabitate?

What is the difference between cohabit and cohabitate? I know the general definition of these words, but I cannot distinguish between the two (i.e., in my mind the definitions are identical).

I see that cohabit is in (Google’s) online dictionary and cohabitate is not, but in practice the two seem to be used interchangeably.


The two terms are synonyms. They both derive from Latin “cohabitare”. Cohabitate is a later formation.

cohabit (v.):

“to dwell together,” specifically “to dwell together as husband and wife,” 1530s, a back-formation from cohabitation (q.v.) or else from Late Latin cohabitare. A euphemism to describe a couple living together without benefit of marriage and usually implying sexual intercourse.

cohabitate (v.):

1630s, from Late Latin cohabitatus, past participle of cohabitare “to dwell together,” from co- “with, together” (see co-) + habitare “to live, inhabit, dwell”.
