Word Origin & History

early 13c., "literary work consisting of a conversation between two or more people," from O.Fr. dialoge, from L. dialogus, from Gk. dialogos, related to dialogesthai "converse," from dia- "across" + legein "speak" (see lecture). Sense broadened to "a conversation" c.1400.
Mistaken belief that it can only mean "conversation between two persons" is from confusion of dia- and di-.
