“A breezy modern name with Gaelic roots”

Origin & Etymology

Kaylei is a creative spelling variant of Kaylee, which itself is a modern American name blending Kay (from Katherine or from the letter K) with the popular -lee suffix. It may also be connected to the Irish and Scottish Gaelic name Caolaidhe, meaning slender. The name exploded in popularity in the 1990s-2000s as part of the -lee/-ley/-leigh naming craze.
