Verbal irony is a figure of speech in the form of an expression in which the use of words is the opposite of the thought in the speaker's mind, thus conveying a meaning that contradicts the literal definition, as when a doctor might say to his patient, " the bad news is that the operation was successful." Dramatic or situational irony is a literary or theatrical device of having a character utter words which the the reader or audience understands to have a different meaning, but of which the character himself is unaware. Irony of fate is when a situation occurs which is quite the reverse of what one might have expected.
