To cause someone to lose a habit or custom; to make unaccustomed to something.
From 'dis-' (reversing) plus 'habit' (from Latin 'habitus' meaning state or condition). The verb reverses the idea of establishing a habit.
While 'dishabituate' is the scientific term, 'dishabit' is its simpler cousin—English often creates parallel simple and complex versions of the same idea, letting different contexts (casual vs. formal) use the right register.
