Etymology: "Imperfectives" is the plural of "imperfective," a grammatical term for verbs or verb forms that present an action as ongoing, habitual or unfinished. The adjective "imperfective" comes from Latin "imperfectivus," built from "imperfectus," meaning "unfinished" or "incomplete," which is itself the negated form of "perfectus," "completed." The base idea is simple: "perfect" in its older sense meant finished or brought to completion, so an imperfective action is one that has not reached that endpoint. The prefix "im-" here is the Latin negating prefix, the same element found in words like "impossible" and "immature." Grammarians used the Latin pair to describe aspect, the way a verb looks at an action's internal progress rather than its time of occurrence. Speakers of English who learn Russian or Spanish meet the same contrast, where one verb form signals "was writing" and another signals "wrote, and finished."
