What is ironic about the conversation between julet and Paris?

Answer 1

In Act IV Paris comes to the Friar's place to make arrangements for his wedding to Juliet and finds his prospective bride there. Juliet knows she is already married and cannot marry Paris, the Friar knows it and the audience knows it. But Paris doesn't know it, and hence everything she says is filled with irony.

Answer 2

The irony in the conversation between Juliet and Paris lies in the fact that Juliet's responses to Paris are filled with double meanings, as she is already secretly married to Romeo. Paris assumes she is mourning Tybalt's death, but she is actually mourning Romeo's banishment. This creates dramatic tension as Juliet must navigate her conflicting emotions in the presence of Paris.
