how much sense does 'hamlet's soliloquy' make?

Does it make sense? Yes, it makes perfect sense. If you cannot understand the words, you might want to look at a translation. Hamlet is intense; he is mourning the death of his father, his mother has married his uncle, and then a ghost shows up (dear old dad) to tell him he was murdered by his stepfather/ uncle. Hamlet is at wits end and although he pretends to have gone mad, we often have to ask if he's really pretending. The soliloquy........ it's masterful.

Note....... Hamlet has its own question and answer forum. If you need to post any further questions, please post them appropriately.

It makes no sense to me.

In Huck Finn it would not make sense. The "Duke" mixes other Shakespeare plays into the soliloquy.
