Kati

Kati is a Finnish and Estonian short form of Katariina and Katarina, which derive ultimately from the Greek name Aikaterine, whose precise root is debated but is commonly associated with the Greek word katharos, meaning pure. The name became widely used across Europe largely through the influence of Saint Catherine of Alexandria, a venerated early Christian martyr. Kati is popular as an independent given name in Finland, Estonia, and Hungary, where it functions as a diminutive of Katalin. Related forms include Katja, Kaja, and Katica.
