sky

sky: [13] Our Anglo-Saxon ancestors called the sky heofon ‘heaven’. Not until the early Middle English period did heaven begin to be pushed aside by sky, a borrowing from Old Norse sky ‘cloud’. This came ultimately from an Indo- European base meaning ‘cover’, which also produced Latin obscūrus, source of English obscure [14]. (For a while English continued to use sky for ‘cloud’ as well as for ‘sky’: the medieval Scots poet William Dunbar wrote, ‘When sable all the heaven arrays with misty vapours, clouds, and skies’.)

sky (n.)

c. 1200, "a cloud," from Old Norse sky "cloud," from Proto-Germanic *skeujam "cloud, cloud cover" (cognates: Old English sceo, Old Saxon scio "cloud, region of the clouds, sky;" Old High German scuwo, Old English scua, Old Norse skuggi "shadow;" Gothic skuggwa "mirror"), from PIE root *(s)keu- "to cover, conceal" (see hide (n.1)).

Meaning "upper regions of the air" is attested from c. 1300; replaced native heofon in this sense (see heaven). In Middle English, the word can still mean both "cloud" and "heaven," as still in the skies, originally "the clouds." Sky-high is from 1812; phrase the sky's the limit is attested from 1908. Sky-dive first recorded 1965; sky-writing is from 1922.
