Kajsa

Kajsa is a Swedish pet form of Katarina, itself the Scandinavian form of Katherine, which derives from the Greek name Aikaterine. The ultimate root of Aikaterine is debated, with proposed connections to the Greek word katharos, meaning pure, among other theories. Katarina and its short forms have been widely used in Sweden for centuries, and Kajsa remains a characteristically Swedish familiar name. Related forms include Karin, Carin, and Kata.
