Etymology

The word "fastest" combines the root "fast," derived from Old English fæst (firm, fixed, swift), with the superlative suffix "-est," originating from Old English -ost. Over time, "fast" evolved to primarily mean "quick," and the suffix "-est" became the standard marker for the superlative degree in English. The logic is straightforward: "fast" (speed) + "-est" (most) = "most quick."
