Irony in "The Cask of Amontillado" by Edgar Allan Poe

Irony is a form of expression, through words or events, which suggest a reality different from and usually contradictory of what is really expected. Writers sometimes say the opposite of what they mean (sarcasm), reverse expectations and end results, or give the reader more information than the characters possess, allowing statements made by the character to only be understood by the reader. These three types of irony are verbal, situation, and dramatic irony, respectively. “The Cask of Amontillado”, written by Edgar Allan Poe, demonstrates irony in a number of different situations.
Among the many ironies within “The Cask of Amontillado”, there are four, which prove to be quite significant. The first one becomes apparent in the opening lines,
