Kaia

Kaia is a Scandinavian and Estonian feminine name, functioning as a short form of Katarina or Katharina, which derive from the Greek name Aikaterine. The ultimate meaning of Aikaterine is debated, but it is often associated with the Greek word katharos, meaning pure. The name is widely used in Norway, Sweden, and Estonia, where it has long been a familiar and affectionate diminutive form. Variant forms include Kaja, Katja, and Kaija.
