Cathie

Cathie is an English diminutive of Catherine, which derives through Latin and Greek Aikaterine from a name of disputed origin, possibly linked to the Greek root katharos, meaning pure. The name Catherine gained widespread use in medieval Europe largely through the veneration of Saint Catherine of Alexandria and later Saint Catherine of Siena. Cathie functions as both an informal short form and an independent given name, and it sits alongside similar pet forms such as Cathy, Kathy, and Kate.
