Cadi

Cadi is a Welsh feminine name functioning as a pet form of Catrin, itself the Welsh equivalent of Katherine. Katherine ultimately derives from the Greek name Aikaterine, whose meaning is debated but is often associated with the Greek word katharos, meaning pure. Cadi has been used in Wales for centuries and remains a distinctly Welsh cultural marker, appearing in traditional folk songs and literature. Catrin, Katarzyna, and Caitlin are among the many European cognates sharing the same ancient root.
