Etymology: "Incredibility" is a plain formation built from the adjective "incredible" and the suffix "-ity," which turns an adjective into a noun for a quality or condition. The adjective came into English from Latin "incredibilis," which combined the negative prefix "in-" with "credibilis," meaning "believable," from "credere," "to believe." So the core of the word is simply "not believable." The noun itself was borrowed from Latin "incredibilitas," and it describes the state of being so unlikely or surprising that it strains belief. Its suffix matches a long line of English nouns like "possibility" and "credibility," which share the same "-ity" ending and the same root in "credere."
