Cajsa

Cajsa is a Swedish given name that developed as a regional spelling variant of Kajsa, itself a diminutive form of Karin, the Scandinavian equivalent of Katherine. Katherine ultimately derives from the Greek name Aikaterine, whose precise root is debated but has long been associated with the Greek word katharos, meaning pure. The name has been in use in Sweden for centuries and gained literary recognition through the Swedish ballad tradition. Related forms include Kajsa, Karin, Katarina, and Katherine.
