Etymology
From un- + habit.
verb
- To make no longer habituated; to disaccustom.“We read indeed how Reuben changed the names of the cities of Nebo and Baalmeon (because their old names, taken from false gods, resented of idolatry, Num. xxxii. 38). But so hard it is to unhabit men's mouths from old ill customs, that it seems their ancient names still prevailed in common discourse.”
