Katie is a nickname for Katherine. Katherine could be derived from Greek meaning "each of the two"; or it could be derived from the name of the goddess HECATE; or it could be related to Greek αικια (aikia) "torture"; or it could be from a Coptic name meaning "my consecration of your name". In the early Christian era it became associated with Greek "pure" and the Latin spelling was changed from Katerina to Katharina to reflect this.
