Sea and sky
Kaylahni is a modern American invention, likely created by blending the popular prefix 'Kay' with the Hawaiian name element 'Lani'. While it does not have a singular ancient origin, its components suggest a connection to the heavens or the royal sky. It follows the trend of rhythmic, multi-syllabic names ending in a vowel sound.
