The short answer
Kaia is a Norwegian and Estonian diminutive of Katarina or Katariina. Behind the Name's cached entry for Kaia does not itself gloss what Katarina/Katariina means, and those parent entries were not in the source set checked for this pass, so the deeper etymology (traditionally tied to the disputed Greek name behind Katherine) is not verified here. It is pronounced KY-ə. In the United States, Kaia ranked #193 among girls' names in 2025 (Social Security Administration).
Meaning and etymology
Behind the Name records Kaia simply as a "diminutive of Katarina or Katariina." Neither Katarina nor Katariina was present in the cached facts checked for this pass, so their meaning — generally the same disputed Greek etymology behind Katherine — is not repeated here as verified fact. Behind the Name also lists Kaia as an Estonian diminutive form in its own right.
