The use of foreshadowing in "Othello" is a crucial part of the play, as it allows the plot to be foreseen by the characters and the audience. Without foreshadowing in "Othello", there would be no created tension created in the audience. As Othello speaks, "Excellent wretch! Perdition catch my soul/ But I do love thee! and when I love thee not/ Chaos is come again" (3.3. 90- 92), the audience becomes tense and apprehensive, as they have been given a preview of "chaos" to come. Iago has manipulated Othello to the point where Othello is now questioning Desdemona's actions, love, and fidelity. In the mentioned quote, Othello is telling Iago that he loves Desdemona so much. On the other hand, however, Othello foreshadows by saying when he stops loving her, chaos will occur. The audience becomes apprehensive and fearful of what will come because Othello said precisely that chaos will come.
