To break or disrupt a habit or custom; to cause someone to lose an accustomed practice.
From dis- (prefix meaning to reverse or negate) + custom (from Old French custume, Latin consuetudo). The verb form suggests removing someone from their usual habits.
Discustom is almost never used today, but it perfectly captures something we experience constantly in modern life—moving to a new culture, changing jobs, or switching to new technology literally means discustoming yourself to old patterns!
