Etymology: The adjective "completive" comes from Latin "complētīvus," a formation built on "complēre," meaning "to fill up" or "to complete." The Latin root combines "com-," an intensive prefix, with "plēre," "to fill," which also gives English words such as "complete" and "replete." The Latin ending "-īvus" marks the form as an adjective that describes a quality or tendency, so the word originally meant something like "tending to complete" or "serving to fill out." In English the word has stayed close to that sense, with "completive" used to describe something that brings an action or process to its finish. Its ending follows a common pattern, in which "-ive" attaches to a verb stem to name a function, much as "tentative" or "informative" do. The word is a learned borrowing rather than a folk word, so its shape reflects Latin grammar more than everyday English speech.
