Etymology: "Bifoliolate" is a botanical term describing a leaf divided into exactly two leaflets, a compound leaf that has two small leaves growing from a single stalk. It is built from "bi-", the Latin prefix meaning "two", attached to "foliolate", which describes a leaf divided into leaflets. "Foliolate" itself combines "foliole", a leaflet, with the adjective ending "-ate", so the whole word simply means "two-leaflet" in its most literal sense. The word belongs to the vocabulary of plant description, where botanists needed precise terms to distinguish leaf shapes from one another. Its parts are transparent: the prefix counts the leaflets, and the rest names what they are. Because the word is a technical coinage assembled from familiar pieces, its meaning has never drifted far from that original sense.
