Etymology: Greek "dichotomia" was built from "dicha", meaning "in two" or "apart", and "temnein", "to cut". The original sense was literal: a cutting into halves. Greek thinkers soon applied it to classification and reasoning, where splitting a whole into two opposed parts became a method. Plato's dialogues repeatedly define things by dividing them into pairs. The same root appears in "tome", "anatomy" and "-tomy" in surgical terms, all of which share the sense of cutting. English took the Greek term as a learned word, so its literal and logical senses both carry through into modern use.
