Meaning
the sky; nature/vocabulary word, ultimately from Old Norse sky
The story
Sky is the English nature word used directly as a name for more than one gender. The word came into English from Old Norse ský, which originally meant cloud; over time English shifted it toward the whole expanse above us. That change gives the name two layers of nature history in one syllable. Sky and Skye look related, but Skye can also point to the Scottish island, so a family's spelling may signal a different story. The American curve begins faintly in the 1950s, grows in the 1990s and 2000s, and holds its strongest level from the 2000s through the 2020s. British skateboarder Sky Brown makes the short form visible on a young public bearer, but the curve was already moving before her career. Sky is modern as a given name and ancient as an English word.
