Etymology: "Valvule" is a small valve, and its history is a matter of a Latin word shrinking itself down with a diminutive ending. The root is Latin "valva," which meant a leaf of a double door, the kind that swings open in two halves. From that physical image, the word came to mean any hinged cover or flap that opens and shuts, and the Romans later used "valvula" for a little valve. English took the term at least partly through French "valvule," which had the same diminutive sense, so the word arrived already carrying its "little" meaning. The suffix "-ule," from Latin "-ula," is the ending that makes a word mean something small, as in "globule" or "capsule," and it is what separates this term from its plainer relative "valve." The two words are doublets: the same Latin source, reaching English by different routes, one as the general word and one as the diminutive.
