Use onomatopoeia to describe the sound of the following occurrence: a mirror breaks in one of the scenes of Hamlet.
It is interesting to think about which scene of Hamlet might contain a mirror breaking. Perhaps a mirror could break in the scene when Hamlet confronts Ophelia, when Hamlet confronts his mother, or when Hamlet participates in the duel. Quite honestly, these are all violent scenes. A beautiful girl like Ophelia when confronted while she is “sewing in her closet” just might have a mirror around. Hamlet confronts Gertrude in her own bedchamber. There is no doubt that there is a mirror in there. Further, there is even more violence after the confrontation when Hamlet kills Polonius. Although there is less of a chance of a mirror to be present during the duel, perhaps there could be one on one of the walls. Any of these could succeed in making a successful crashing sound as it breaks.
Onomatopoeia, of course, is a literary term for an actual sound. In regards to a mirror breaking, as in the scenes above from Hamlet, the sound could be either “crack” or “smash” or “crash.” My suggestion would be to follow up the sound with an exclamation point.
