Caja

Caja is a Danish feminine name functioning as a diminutive or short form of Katarina, the Scandinavian form of Katherine, which itself derives from the Greek name Aikaterine, whose meaning is debated but may relate to a root meaning pure. The name follows a common Nordic pattern of creating pet forms through simplified, softened syllables. It remains rare in Danish-speaking regions. Related forms include Kaja, the more widely used Scandinavian variant, as well as Katarina and Katherine across European traditions.
