Light, pretty and distinctive in appearance, Carys is one of that sweet group of girl names with a loving meaning. A relatively modern name, it didn't come into use in its native Wales until the late nineteenth century, and even then, it wasn't a mainstream choice until the middle of the twentieth century. Pronounced as CA-riss, the beginning sound is like the one cat or Catherine, not said to rhyme with Claire.
