Meaning: Of Caitlin; Pure

While Cailynn is certainly not the most common form of Caitlin, it's without a doubt one of the sweetest! It's rooted in the Greek word katharos, which inspired Katherine, and means simply "pure." As baby grows, this name will remind them of your unconditional love, wrapping them up in a warm hug when you're not near. Plus, the 'c' in Cailynn instead of the more contemporary 'k' adds a touch of timeless sophistication.
