[Origin: 1175–1225; ME < ON skȳ cloud, c. OE scéo cloud]
c.1220, "a cloud," from O.N. sky "cloud," from P.Gmc. *skeujam "cloud, cloud cover" (cf. O.E. sceo, O.S. scio "cloud;" O.H.G. scuwo, O.E. scua, O.N. skuggi "shadow;" Goth. skuggwa "mirror"), from PIE base *(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 M.E., the word can still mean both "cloud" and "heaven," as still in the skies, originally "the clouds." Sky-high is from 1818; phrase the sky's the limit is attested from 1920. Sky-dive first recorded 1965; sky-writing is from 1923.
the part of space above the earth, in which the sun, moon etc can be seen; the heavens Example: The sky was blue and cloudless; We had grey skies and rain throughout our holiday; The skies were grey all week.
