Irony is a form of expression in which the real meaning is concealed or contradicted by the words or images used ? a meaning which either markedly contrasts or is entirely opposite to that which appears to be presented. It is a trope in which there is an incongruity between what might be expected and what actually occurs. Irony involves the perception that things are not what they seem to be. The intention of one who uses irony is usually to imagine that there are two kinds of people in the audience: the first kind will not understand that what they see does not carry the ultimate meaning, and the other is aware that there is more meaning intended, and also that the first kind of person doesn't understand this. Irony is a means of expressing an attitude which is disguised by what what will seems to be obvious. The effect of irony is usually intended to be humorous, dramatic, tragic, insulting (sarcastic), or absurd. Irony is essential to satire. When irony is presented by pretending ignorance, is is the kind also called "Socratic irony." "Ironic" is the adjectival form: relating to, characterized by, using, or containing irony.Also see ambiguity, amphibolous, coherence, incoherence, compare, counterpoint, cryptic, illusion, juxtaposition, metaphor, nuance, parody, point of view, and simile.
