Etymology: "Idiot-proof" is a plain compound: "idiot" plus the suffix "-proof," meaning "resistant to" or "protected against." The "-proof" element is the older and more interesting half. It comes from "proof" in the sense of a trial or test, as in "proof" of a spirit or "proof" of a printing plate, and it came to mean "able to withstand" in the 1600s, as in "waterproof" and "bulletproof." Attaching it to a person's name or label to mean "impossible to get wrong" is a later, playful extension of that pattern. The first half traces back to ancient Greece. "Idiōtēs" meant a private person, someone who did not hold public office, and from there it came to mean a layman or an ordinary person without special knowledge. Its descent into insult happened gradually, passing through Latin "idiota" and Old French "idiote" before reaching Middle English as "ydiote," meaning an uneducated or unlearned person. The modern sense of a foolish person arrived only later, so the word has moved from "private citizen" to "fool" over two thousand years.
