Kadi

Kadi is an Estonian and Finnish feminine name derived from the same Germanic root as Katherine, ultimately tracing back to the Greek Aikaterine, whose meaning is debated but often connected to the Greek katharos, meaning pure. It functions as a regional vernacular form that developed independently in the Baltic and Finnic cultural sphere. Related forms include Kadri, the more widely used Estonian cognate, as well as Katri, Kaisa, and the broader Katherine family across European languages.
