Down in Tartarus youths and maidens spend their time dismally in asking if there be yet an earth and a sky up above.
Over us the sky up to the zenith Palpitates with tense glitter: About our keel the foam bubbles and curdles In phosphorescent joy.
They decided that, as they wished to remain upon the earth, they must push the sky up into place.
I leave it and climb higher—nearer to the sky—up the steep sides of the Cordilleras—up to the tierra fria.
If I told you I came from another planet, another world in the sky up among the stars, would you believe me?
They had all—at the time I kind of glanced and they were still flying around in the sky up there.
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.
"to raise or throw toward the skies," 1802, from sky (n.).
