fast; quick · spicy; hot · harsh; acrid; biting; sharp
köken: From Middle Persian [script needed] (twnd /tund/, “sharp, violent”), from Proto-Iranian *tund- (“to act violently”), from Proto-Indo-Iranian *tund-, from Proto-Indo-European *tu-n-d-, ultimately from Proto-Indo-European *(s)tewd-.
köken: Reborrowed from Persian تیز (“fast”), ultimately from Proto-Turkic *tēŕ- (“fast, quick”). Cognate with Kazakh, Kyrgyz тез (tez), Uzbek, Turkish tez (“quick”), etc.
quickly, without delay; often used when urging someone to hurry
eş: 얼른, 후딱
köken: First attested in the Seokbo sangjeol (釋譜詳節 / 석보상절), 1447, as Middle Korean ᄲᆞᆯ리〮 (Yale: spòllí), equivalent to modern 빠르— (ppareu-, “to be quick”) + -이 (-i, adverb-deriving suffix).
köken: Attested since 1609 according to Nationalencyklopedins Ordbok, from Middle Low German fôrt (“away, further, forward”), which is used adverbially (forts) with the same meaning in Low German, from Middle Low German fort, from Old Saxon forth. Related to för (“fore”), före (“before”) and forsla (“transport, carry, haul”).
köken: Inherited from Latin rapidus and Latin rapidē. The -e declension derives from the adverb, the two having been conflated at some point. The rarely used western Transylvanian variant rapăd preserves the adjectival declension. Thus there must have been two distinct forms for the adjective and adverb originally; rapăd and *rapede respectively. Doublet of rapid.
