The narrator calling Fortunato his friend is an example of verbal irony because he doesn't see him as a friend he actually sees him as the complete opposite.
the cough is a mere nothing; it will not kill me. I shall not die of a cough.
This is an example of situational irony because Montresor used reverse psychology on his servants to be sure that they were NOT home when he brought Fortunato home.
my friend no; i will not impose upon your good nature. percive you have an engagement.
An example of dramatic irony occurs when Montresor tells Fortunato he is also a mason. Fortunato asks for a sign. “It is this,” I answered, producing from beneath the folds of my roquelaire a trowel." this is dramatic irony because the readers know tgat he is in fact not a mason.
come let us go!
montresor responds by saying "true" when fortunato says he won't die from a cough; by doing so he allows the reader to suspect that there is another more devious, sinister plan in the making.
this foreshadows fortunatos doom because the reader knows that montresor hates fortunato and is probobly trying to find a way to kill him without getting caught
i have no engagement; come.
this is foreshadowing bcause montresor is lureing fortunato into the catacombs which gives the reader a sinister feeling.
