çekim: karşılaştırma flinker · üstünlük am flinksten
eş: fix, flott, geschwind
köken: Via German Low German from Middle Low German flink (“gleaming”). Perhaps ultimately related to Proto-Germanic *flakurōną (“to flutter, beat repeatedly”).
köken: Cognate to Central Kurdish باڵندە (ballinde), پاڵوانە (pallwane), پاڵووێنە (palluwêne). The elements parse as برز (burz, “high”) + Middle Persian 𐫇𐫀𐫏- (wāy-, “to fly, to soar”, from Proto-Iranian *wáyHti) + ـه (-a, notorious noun-deriving suffix).
köken: Reborrowed from Persian تیز (“fast”), ultimately from Proto-Turkic *tēŕ- (“fast, quick”). Cognate with Kazakh, Kyrgyz тез (tez), Uzbek, Turkish tez (“quick”), etc.
çekim: karşılaştırma gezwinder · üstünlük gezwindst
köken: Borrowed from German geschwind (late 16th century), a prefixed variant of Middle High German swind, from Old High German *swind, from Proto-Germanic *swinþaz. Thence also English swith, Gothic 𐍃𐍅𐌹𐌽𐌸𐍃 (swinþs).

köken: Many dialectal variants (hailakka, haijakka, haitakka). hailakka may be the original as it is also found in Karelian, which also has Karelian hailata (“to rush, run around”). If so, it may be from hailakka (“pale, faded, wishy-washy”), as fast things have an indistinct colour. The consonant variations would be sound-symbolic.
