The story of Sky
Sky and Skye entered American given-name use in the 1970s among the nature words, alongside Rain, Star and River. Skye is separately a Scottish island whose name is Norse or Gaelic. Masculine Sky appears in the American registers steadily from that decade and is in current use.
Meaning
cloud, sky
From the Old Norse ský, 'cloud'. English had heofon for the sky and borrowed ský for the clouds; over several centuries the borrowed word took the whole space and the native one went to heaven. The shift is documented in the record of the language.

The Ronney test
Every popular name lives one long story — a climb, a peak, a slow settling back. Sky's later chapters haven't been written yet, so we borrowed them: Ronney climbed just as high around 1955, and its whole arc is on record. Line the two peaks up, and Ronney's path sketches the road Sky is walking now.

The trade-off

- Three letters, one syllable, and never misheard.
- Skyler is available as a longer formal alternative.
- It is an ordinary English noun and never reads as purely a name.
- It is thoroughly unisex and reads as more feminine in America.
- It is very short and can be swallowed by a long surname.
