Katie
/ˈkeɪ.ti/
Katie is a diminutive of Katherine, from the Greek Aikaterine, whose origin is debated.
The most widely accepted theory connects it to the Greek katharos, meaning “pure.” Early Latin sources also associated it with Hecate, the Greek goddess, though that link is now considered less likely.
Katherine entered England with the Normans and became one of the most durable names in the English language. Diminutives—Kate, Katie, Katy, Katya—spread across Europe as the name naturalised in each language family.
