Life or waterfall
Chailyn is a modern American invention likely created by blending the Hebrew name Chai, meaning life, with the popular English suffix -lyn. It may also be interpreted as a variant of the Gaelic name Kaylin or a combination of the name Shay and Lynn. Its usage is rare and reflects contemporary naming trends of the late 20th and early 21st centuries.
