Etymology: "Ternarius" is a Latin adjective meaning "consisting of three" or "threefold," formed from "terni," "three at a time," a distributive numeral related to "tres," "three." The suffix "-arius" marks a relationship or belonging, so the word describes something that belongs to a group of three, much as "binarius" describes a pair. In English, "ternary" is the descendant of this Latin adjective, and it keeps the sense of threefold grouping in technical contexts. Mathematicians use it for systems built on three values, and chemists and computer scientists apply it to compounds or number systems with three components or states.
