Kaidi

Kaidi is an Estonian feminine given name derived from the Estonian form of Katherine, which itself traces back to the Greek name Aikaterine, possibly connected to the Greek word katharos, meaning pure. It functions as a colloquial or pet form alongside Kadri, another Estonian equivalent of Katherine, and shares its ultimate heritage with international variants such as Katherine, Katarina, and Katja. The name has been in steady use in Estonia through the twentieth and twenty-first centuries as an independent given name rather than merely a diminutive.
