Answer: One example of foreshadowing in Shakespeare's Romeo and Juliet is in Act 1 Scene 1, when Tybalt draws his sword at the Montagues and declares his hatred for them.
Step-by-step explanation:
We the reader see this as establishing the rivalry between Montagues and Capulets, however we later come to the realization that this is foreshadowing of Tybalt's duel with Romeo in Act 3 Scene 1. This example of foreshadowing drives the plot forward by contributing to the thematic idea that love is violent. Without foreshadowing, many of the thematic ideas in this play would have a weaker delivery and less evidence to support them.
