To separate or break apart; to cause people or groups who were united to come apart.
From dis- (reverse/separate) + unite (from Latin 'unus' one), meaning to undo the state of being united or to force separation between joined elements.
While 'disunite' and 'divide' seem similar, 'disunite' specifically suggests breaking something that *was* bonded together, carrying emotional weight—it's about betrayal or fracture, not just difference.
