A ialogue (sometimes spelled dialog) is a reciprocal conversation between two or more entities. The etymological origins of the word (in Greek διά("diá," through) and λόγος ("logos," word, speech) creating concepts such as 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 erroneous assumption that a dialogue is necessarily between only two parties.
