fastest-growing
UK: ˈfɑːstɪst ˈɡrəʊɪŋ | US: ˈfæstɪst ˈɡroʊɪŋ
adj. increasing in size, quantity, or importance at a higher rate than others
adj. (of a business or industry) expanding more rapidly than comparable sectors
The word combines "fast" (Old English fæst, meaning firm or quick) with the superlative suffix "-est," indicating the highest degree of speed. "Growing" derives from Old English grōwan (to flourish or increase), with "-ing" forming the present participle. The compound reflects a logical progression: "fast" (speed) + "growing" (expansion), emphasizing rapid development relative to peers. Historically, "-est" and "-ing" are Germanic suffixes, while "grow" shares roots with Proto-Indo-European ghre- (to become green).
