Catharine

Catharine is an English feminine name and a spelling variant of Catherine, which derives from the Greek name Aikaterine. The ultimate root of the Greek form is uncertain, though it has long been associated by folk etymology with the Greek word katharos, meaning pure, an association that influenced the spelling with a th in many European languages. The name was borne by numerous saints, most famously Catherine of Alexandria, as well as by queens and empresses across Europe. Related forms include Katherine, Katarina, Katarzyna, and Ekaterina.
