What is "isocolon"

n. (context rhetoric English) A figure of speech in which parallelism is reinforced by members that are of the same length.

Isocolon is a figure of speech in which a sentence is composed of two or more parts ( cola) perfectly equivalent in structure, length and rhythm: it is called bicolon, tricolon, or tetracolon depending on whether they are two, three, or four. A well-known example of tricolon is Julius Caesar's "Veni, vidi, vici" ("I came; I saw; I conquered).

The term is derived from the Greek (ísos), "equal" and (kôlon), "member, clause". The plural is '-cola' but in English may also be '-colons'.
