Irony: a subtly humourous perception of inconsistency, in which an apparently straightforward statement or event is undermined by its context so as to give it a very different significance. In various forms, irony appears in many kinds of literature, from the tragedy of Sophocles to the novels of Jane Austen and Henry James, but is especially important in satire, as in Voltaire and Swift. At its simplest, in verbal irony, it involves a discrepancy between what is said and what is really meant, as in its crude form, sarcasm; for the figures of speech exploiting this discrepancy, see antiphrasis, litotes, meiosis. The more sustained structural irony in literature involves the use of a naïve or deluded hero or unreliable narrator, whose view of the world differs widely from the true circumstances recognized by the author and readers; literary irony thus flatters its readers' intelligence at the expense of a character (or fictional narrator). A similar sense of detached superiority is achieved by dramatic irony, in which the audience knows more about a character's situation than the character does, foreseeing an outcome contrary to the character's expectations, and thus ascribing a sharply different sense to some of the character's own statements; in tragedies, this is called tragic irony. The term cosmic irony is sometimes used to denote a view of people as the dupes of a cruelly mocking Fate, as in the novels of Thomas Hardy. A writer whose works are characterized by an ironic tone may be called an ironist. For a fuller account, consult D. C. Muecke, Irony and the Ironic (1982).
