1. A conversation between two persons; dialogue.

   “This duologue had, of course, left Wilbert Cream a bit out of it, just painted on the backdrop as you might say, and for some moments, knitting his brow, plucking at his moustache, shuffling the feet and allowing the limbs to twitch, he had been giving abundant evidence that in his opinion three was a crowd and that what the leafy glade needed to make it all that a leafy glade should be was a complete absence of Woosters [myself].”

2. A dramatic performance or piece in the form of a dialogue limited to two speakers.
