Word Origin for sky

C13: from Old Norse skӯ; related to Old English scio cloud, Old Saxon skio, Old Norse skjār transparent skin

Word Origin and History for sky
n.

c.1200, "a cloud," from Old Norse sky "cloud," from Proto-Germanic *skeujam "cloud, cloud cover" (cf. 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.

v.

"to raise or throw toward the skies," 1802, from sky (n.).
