What kind of words would a writer use to express a tone of irony in a literary work?

diction, paradox, juxtaposition, character actions, plot or dialogue are the terms i dont know what words correlate im so sorry!

Irony is a figure of speech in which words are used in such a way that their intended meaning is different from the actual meaning of the words. It may also be a situation that may end up in quite a different way than what is generally anticipated. In simple words, it is a difference between the appearance and the reality.
