Etymology: "Certificative" is built from "certify" and the suffix "-ative," which forms adjectives meaning "tending to" or "serving to" perform an action. "Certify" comes from Latin "certificare," "to make certain," which joins "certus" ("sure, settled") and "facere" ("to make" or "do"). The Latin roots explain the sense. Something certificative makes a claim certain by putting it on record, which is why the adjective fits official attestations of validity or quality.
