Etymology: "Nonfulfillment" is a plain English compound: the prefix "non-," meaning "not," attached to "fulfillment," the noun from "fulfill." "Fulfill" itself is built from "ful-," an old spelling of "full," and "fill," so the core idea is making something full or complete, and "fulfillment" describes the act or state of bringing a promise, duty, or expectation to completion. Adding "non-" simply reverses that sense: "nonfulfillment" names the condition of a promise, requirement, or obligation left unmet. Because "non-" can be attached to almost any noun in English, the word is a transparent formation rather than a borrowing, and it reads straightforwardly as "the state of not being fulfilled."
