A conversation or literary work featuring exactly two speakers or participants; sometimes called a two-person dialogue.
From duo- or dual- (two) + -logue (from Greek logos, speech). This is a blended or analogical formation based on the word dialogue, with the prefix changed to emphasize the number two.
While dialogue means conversation between any number of people, dualogue emphasizes the special intimacy of just two—which is why many of literature's most intense scenes, from Hamlet and his mother to modern plays like 'Two for the Seesaw,' are dualogues.
