Etymology: "Intestinum" is the Latin word for the bowels or entrails, and in its earliest sense it referred to the inner parts of the body in general rather than one particular organ. Its root is the adjective "intestinus," meaning "internal" or "inward," formed from "intus" ("within") with a suffix that marks something as belonging to a place. The same root gives us "intestine" in English, which entered the language in the late 1300s through Old French "intestin" and was used for the digestive tract as a single organ by the 1500s. The Latin noun was often used in the plural, "intestina," which is why English has long sometimes used the word as a plural form. The modern anatomical sense, dividing the tract into small and large intestines, developed through the work of early anatomists who used the term for the coiled passage between the stomach and the anus. Because the word originally meant only "what lies within," it could describe the insides of almost anything, and the narrowing to a single body part happened gradually over centuries of medical writing.
