Sea and sky; pure
Caylani is a modern American invention, likely created by blending the name Kay or the prefix Cay- with the popular Hawaiian-inspired suffix -lani. While it lacks a singular ancient root, it is often associated with 'lani' meaning 'heaven' or 'sky' in Hawaiian, and 'pure' from the Greek roots of Kay.
