Kaja

Kaja is a Scandinavian and Slavic feminine name with roots in two distinct traditions. In Scandinavian use, it functions as a short form of Katarina, itself derived from the Greek Aikaterine, whose meaning is debated but often associated with the Greek katharos, meaning pure. In Slavic and Baltic contexts, particularly in Estonian, Polish, and Slovenian, Kaja carries similar associations as a diminutive of Katarzyna or related Katherine forms. Katja and Katya are closely related diminutive variants found across European traditions.
