Etymology: "Stealthiest" is the superlative of "stealthy," so its story is really the story of "stealth" plus a common English ending. The base noun "stealth" comes from the Middle English "stelthe," which meant theft or the act of stealing, and it is built on the same Germanic root that gave English "steal." The suffix "-y," which turns a noun into an adjective meaning "characterised by" or "full of" (as in "healthy" or "milky"), was added to form "stealthy," meaning secretive or done with quiet caution. The superlative "-iest" then marks the highest degree of that quality. Only a single short paragraph is needed here, because the word is a straightforward noun-plus-suffix formation with no dramatic shift in meaning. The sense of "stealth" has moved from the concrete act of theft toward the broader idea of acting covertly, while the endings simply follow ordinary English patterns for building adjectives and their superlatives.
