Etymology: "Disillusioner" is formed from the verb "disillusion" with the agent suffix "-er," so it means, literally, one who disillusions. The verb itself was borrowed into English from French "désillusionner" in the 1600s, and it is built on "illusion," from Latin "illusio," a mocking or deceiving, from "illudere," to play with or mock. The prefix "dis-" reverses the action, so to disillusion someone is to strip away the illusion they were living under. The agent noun followed the verb's pattern rather than arising from a separate tradition of its own. English speakers readily attach "-er" to verbs like "teach," "lead," and "disappoint," producing "teacher," "leader," and "disappointer," so a noun for the person who disillusions was a natural addition once the verb was established. Because it is a regular derivation, it has no famous coiner, and its earliest recorded uses are unremarkable. The French verb it descends from carries the same sense of a shattered belief, so the English word reflects the original idea without any significant shift in meaning.
