dusk

dusk: [OE] In Anglo-Saxon times, dusk was an adjective meaning ‘dark in colour’ (a sense preserved today in the derived adjective dusky [16]). Its modern noun use ‘twilight’ is not recorded until as recently as the early 17th century. The Old English form of the word was dox, which was descended from the same ultimate Indo-European ancestor as Latin fuscus ‘dark’ (source of English obfuscate [16]).
=> dun, obfuscale

dusk (n.)

c. 1200, dosk "obscure, to become dark," perhaps from Old English dox "dark-haired, dark from the absence of light" (cognate with Swedish duska "be misty," Latin fuscus "dark," Sanskrit dhusarah "dust-colored;" also compare Old English dosan "chestnut-brown," Old High German tusin "pale yellow") with transposition of -k- and -s-, perhaps via a Northumbrian variant (compare colloquial ax for ask). But OED notes that "few of our words in -sk are of OE origin." A color word originally; the sense of "twilight" is recorded from 1620s.
