Etymology: Nonconsuming is a plain formation: the prefix "non-" attached to "consuming," the present participle of "consume." The verb itself traces back through Old French "consumer" to Latin "consumere," built from "con-" (together, thoroughly) and "sumere" (to take up), so its sense of taking something up completely gave English the idea of using something up. "Consuming" in the sense of using up or devouring is the base, and "non-" simply negates it. The pattern is a familiar one. English has long attached "non-" to participles and adjectives to mark the absence of a quality, as in "nonstop" or "nonbinding," and "nonconsuming" follows the same logic: a thing that does not use up what it draws on. Its meaning is therefore the negation of a sense that developed in English well before it.
