Ciara and
Kai are in the database already. You could've easily found them by searching on the main page of Behind the Name. Next time, please do so. Now, just click on
Ciara or
Kai's hyperlink to see their meanings.
Ciara is pronounced either KEER-ah or KEE-ah-rah, depending on geography and who you ask. Both pronunciations are correct, though I personally prefer the former.
Kai is not Irish, no matter what anyone says. It's Hawaiian, Scandinavian, or Old Norse, depending on the etymology. Additionally, it could be construed as ultimately
Roman, if you go with the "form of
Gaius" route.
