Brabantio is saying, “Roderigo, I appreciate your effort, and I’ll repay you for the trouble you’ve taken.”

Roderigo is saying, “I’m coming to you honestly and with good intentions.”

Roderigo says Iago “hast had my purse as if the strings were thine,” which suggests Iago has been taking his money freely. What’s unclear to me is why Roderigo keeps trusting Iago financially even though he clearly feels used. Why doesn’t he break off the relationship if he already suspects Iago is exploiting him?

Required Annotation: In Cinthio’s tale, the Ensign’s wife is a quiet, almost background figure who spends her days with the Moor’s wife, but Shakespeare transforms her into Emilia, a character with moral force who ultimately exposes Iago’s plot. Shakespeare likely made this change to heighten the emotional and ethical stakes of the story, giving Desdemona an advocate who speaks truth when no one else will. By allowing Emilia to confront Iago and denounce his manipulation, Shakespeare shifts the meaning of the story toward silence showing how speaking out against wrongdoing becomes a form of resistance that Cinthio’s version never explores.
