What Does the Name Kaii Mean?
In English, Kaii is usually a spelling variant of Kai, formed by adding a second i to the end. The name Kai has several independent origins, so Kaii does not have a separate etymology. In Hawaiian, kai is the word for 'sea' or 'ocean,' and it is used as a given name. In Japanese, the sound kai is written with various kanji, most commonly 海 ('sea, ocean'), and the meaning depends on the characters chosen. In Scandinavian languages, Kai is a male given name often linked to the Latin name Caius, a Roman family name of uncertain meaning; some sources also connect it to a Frisian root. The extra i in Kaii is a spelling variation, not an additional etymological element.
