Kadi

Kadi is an Estonian and Finnish feminine name that developed as a vernacular short form of Katariina, the Nordic adaptation of the Greek Aikaterine, whose root meaning remains disputed but is often associated with the element katharos, meaning pure. It has been a familiar everyday name in Estonia for centuries, functioning both as an independent given name and as a pet form. Related forms include Kadri, Kati, and Katja, all tracing back ultimately to the same Greek source.
