Iyla is a modern spelling that blends two popular names: Isla, the Scottish name of the island of Islay, which means "island", and Ayla, which is Turkish for "moonlight" and also a Hebrew word for an oak tree. The spelling keeps the sound of both while looking new. Iyla had fewer than five US births in 2000, entered the top 1000 in 2020 and has climbed to number 525 in 2025, its highest rank so far.
