Karen

Karen is a Danish and Norwegian short form of Katherine, itself derived from the Greek name Aikaterine, whose root meaning is debated but often linked to the Greek katharos, meaning pure. The name spread widely across Scandinavia and became highly popular in English-speaking countries during the mid-twentieth century. Notable bearers include Danish author Karen Blixen, who wrote under the pen name Isak Dinesen. Related forms include Katherine, Katarina, Caren, and Karin.
