Sea or ocean
Kaimen is a modern phonetic variant likely derived from the Japanese name Kai, meaning sea or ocean, or potentially a variation of the Cornish name Kelyn. It is often chosen for its coastal associations and contemporary sound. In some contexts, it is viewed as a creative spelling of the name Cayman, referring to the Caribbean islands.
