dialogue

n. conversation, discussion, talk

A dialogue (sometimes spelled dialog) is a reciprocal conversation between two or more entities. The etymological origins of the word (in Greek διά(diá,through) + λόγος(logos,word,speech) concepts like flowing-through meaning) do not necessarily convey the way in which people have come to use the word, with some confusion between the prefix διά-(diá-,through) and the prefix δι-(di-, two) leading to the assumption that a dialogue is necessarily between only two parties.
