Final answer:
The use of irony in Edgar Allan Poe's 'The Cask of Amontillado' enhances the story's suspense and engages the reader.
Explanation:
Irony is demonstrated in the excerpt from Edgar Allan Poe's 'The Cask of Amontillado' when the character Fortunato dismisses the seriousness of his cough, claiming it will not kill him. This is ironic because the reader knows that his fate is indeed tied to his cough, leading to his demise.
This serves as an example of dramatic irony, where the audience has more information than the character, creating tension and an ironic twist in the story.
In Poe's text, the use of irony heightens the suspense and adds a layer of complexity to the plot, engaging the reader in the unfolding events.
