Final answer:
Iago's language at the end of Act Two in Othello changes from verse to prose, signaling a shift in his tone and character. Shakespeare may have used this change to emphasize Iago's deceitfulness and manipulative nature.
Step-by-step explanation:
At the end of Act Two in Shakespeare's Othello, the language used by Iago changes from verse to prose. Previously, Iago had been speaking in verse, which is a poetic form of language. The shift to prose signifies a change in Iago's tone and character. He becomes more direct and manipulative, using plain and straightforward language to deceive and manipulate those around him.
Shakespeare may have employed this change in language to emphasize Iago's deceitfulness and subterfuge. By switching from verse to prose, Shakespeare highlights Iago's true intentions and the calculated nature of his actions. This change in language also serves to create a stark contrast between Iago and the other characters, further establishing Iago as a master manipulator.
