Simplified etymology

Sky was borrowed from a Scandinavian language in Middle English and originally meant “cloud.” It later came to denote the heavens generally and was applied to a shade of blue in the mid-17th century.

Etymology

The noun is derived from Middle English sky (“sky; cloud; mist”), also spelled ski, skie, [and other forms], from Old Norse ský (“cloud”), from Proto-Germanic *skiwją (“cloud; sky”), from *skiwô (“cloud; cloud cover, haze; sky”) (whence Old English sċēo (“cloud”) and Middle English skew (“air; sky; (rare) cloud”)), from Proto-Indo-European *(s)kewH- (“to cover; to conceal, hide”). Partly displaced Old English heofon, which survives in the reflex heaven, still sometimes used in the sense of sky, but usually in high or poetic register. The verb is derived from the noun.
