Kitty is a nickname for Katherine which comes from Greek Aikaterine though the etymology behind the name is not certain. It could be derived from another Greek name, Hekaterine from hekateros meaning “each of the two” or from Hecate, the name of the Greek goddess of witchcraft, the underworld, and crossroads, from hekas possibly meaning “far off” though another theory states it comes from a Greek word meaning “will”. It might also be derived from Greek aikia “torture”. Katherine could also be from a Coptic name meaning “my consecration of your name”. The spelling of the name was later changed to be associated with Greek katharos “pure”. Kitty is also a word used to refer to a kitten.
Origin: Ancient Greek, Coptic
