Irony
Irony (from Ancient Greek εἰρωνεία (eirōneía), meaning "dissimulation, feigned ignorance"), in its broadest sense, is a rhetorical device, literary technique, or event in which what appears, on the surface, to be the case, differs radically from what is actually the case. Irony may be divided into categories such as verbal, dramatic, and situational.
Verbal, dramatic, and situational irony are often used for emphasis in the assertion of a truth. The ironic form of simile, used in sarcasm, and some forms of litotes can emphasize one's meaning by the deliberate use of language which states the opposite of the truth, denies the contrary of the truth, or drastically and obviously understates a factual connection.
Other forms, as identified by historian Connop Thirlwall, include dialectic and practical irony.
Definitions
Henry Watson Fowler, in The King's English, says "any definition of irony—though hundreds might be given, and very few of them would be accepted—must include this, that the surface meaning and the underlying meaning of what is said are not the same." Also, Eric Partridge, in Usage and Abusage, writes that "Irony consists in stating the contrary of what is meant."
