The opening lines in Romeo and Juliet take the form of a sonnet that anticipates the themes and actions throughout the play. We are told that "Two households", that is, two noble families, hold an ancient grudge and that "civil blood makes civil hands unclean". This tells us about the violence that will engulf the play. We also hear about "star-cross'd lovers" that will lose their lives because of their families' strife. Thus we know from the start of the play that both protagonists of this love story are doomed to die. And though this will be a tragedy, not all is lost: the death of the young lovers shall bring both families together, putting an end to the bloodshed.
