Hamlet interacts with osric in act 5, scene 2. what function does this interaction have in the play?

The interaction of Hamlet and Osric is to provide a comic relief to the play.

Explanation:

William Shakespeare's tragedy play "Hamlet" is about the revenge of the death of the senior Hamlet at the hands of his brother Claudius. The young prince Hamlet was instigated and made known by his father's ghost about the murder which brought forth the whole sequence of the play.

Act V scene ii of the play shows the interaction of Hamlet with Osric, a courtier. The courtier had been sent by the king Claudius to tell him about the bet he had made regarding the duel of Hamlet and Leartes. Claudius and Leartes had planned a duel where Hamlet would be killed. Osric was the messenger/ relayer of information. We can also deduce from this scene that he will do anything to make a place for himself, and that his position in the king's court matters to him more than anything. But with the way Hamlet responds and plays down his words provides a humorous tone to the serious issue of the impending duel. This interaction gives a much needed comic relief in between the whole play.
