Etymology: "Indivisible" is built from two familiar parts: the prefix "in-", meaning "not," and "divisible," which comes from "divide." Something divisible can be split into parts, so the indivisible is what cannot be split. The word passed into English from Middle French "indivisible," which in turn drew on the Late Latin "indivisibilis," a term used for things that could not be cut apart. The root beneath "divide" traces back to a very old Indo-European base meaning "to divide" or "to cut in two," the same ancestor that gave rise to "two" and "dual." That deep link is why the idea of splitting and the idea of pairs sit so close together in the family of words.
