Example: In Act 1 Scene 4, line 50 , the witches hail Macbeth, “thane of Cawdor!”
Dramatic irony: At this point, Macbeth is unaware that the king has conferred this honor upon him because of his valor in battle, so he attributes his fortune to the witches’ prophecy. However, the audience knows Duncan made the pronouncement in Act 1, Scene 3.
Purpose: This dramatic irony is to show Macbeth’s belief that the witches speak the truth and are responsible for his success. This belief can, and does, influence his future actions.
Example: In Act 1, Scene 6, line 1, Duncan says, “This castle hath a pleasant seat”
Dramatic irony: When Duncan reaches the castle, he feels secure and welcome at the home of his loyal kinsmen. However, the audience is aware that he may be murdered that very night. It is also ironic that he calls the castle “a pleasant seat”, when it’s the place where he is eventually killed.
Purpose: This irony is to contribute to suspense. Since the audience knows more than the character, the audience is positioned to wait for the character to gain awareness.

Of course, since the witches’ prophecies
