Etymology: Rusty is about as plain as English etymology gets: it is "rust" with the adjective-forming suffix "-y" attached, and the root goes back to Old English "rūst," itself shared across the Germanic languages. The adjective "rūstiġ" already existed in Old English and passed into Middle English as "rusty," so the pairing of a noun and a suffix has been stable for well over a thousand years. Neighbouring languages show the same pattern, with Dutch "roestig," German "rostig," and Swedish "rostig" all built on the same root. The word also has a less obvious side. "Rusty" was once a variant of "resty," an older adjective meaning something like stale or spoiled, and the two forms seem to have merged over time. The sense of corroded iron came to dominate, but the word's history includes a sideline in which "rusty" and its sense of decay were linked to other older meanings.
