Etymology: "Dustproof" is about as plain as English compounds get: it joins "dust" to "-proof," the suffix meaning "resistant to" or "impervious to," as in "waterproof" or "fireproof." The pattern is old and productive. "-proof" began as a noun-forming element in English, from the sense of a trial or test, and gradually became a suffix that could be attached to almost any material to name what it keeps out. The word therefore describes a construction, not a coined term with a story behind it. Something is dustproof when it is sealed so that fine particles cannot get in, whether that is a camera body, a cabinet, or an electronic device. Its meaning follows straight from its parts: "dust" as the thing excluded, and "proof" as the quality of withstanding it.
