To separate or disconnect two things that are joined together; to part or divide.
From dis- (apart) + join (from Latin iungere, 'to join'). Literally means 'to unjoin' or 'to separate things that are connected.'
English loves the dis- prefix for reversing actions—we have join and disjoin, connect and disconnect, appear and disappear. It's efficient because it lets us quickly express opposites without needing entirely new words.
