Etymology: "Adequative" is built from Latin "adaequare," meaning "to make equal to," itself formed from "ad-" ("to") and "aequus" ("equal," "level"). The same root gives English "equal," "equate," and "equity," so the word's core idea is one of matching or making things even. The adjective passed through Medieval Latin "adaequativus," a later formation that carried the sense of making something correspond to a standard. The word's meaning follows that logic. Something adequative stands in as a workable match for something else, supplying a sufficient or acceptable equivalent where the original is absent or unavailable. Its meaning stays tied to the notion of equalizing, so a substitute counts as adequative only when it truly measures up.
