Kaycee

Kaycee is a modern variation of the name Casey, which is an English surname derived from the Irish Gaelic name 'Cátsaidhe'.

The name 'Cátsaidhe' is thought to have originated from the Irish Gaelic word 'cath', meaning 'battle' or 'warrior', combined with the word 'sidhe', referring to a fairy or supernatural being.

While the original meaning of the name Casey is related to warriors and battles, the modern variation Kaycee has taken on a more gender-neutral and contemporary tone, making it a popular choice for both girls and boys.

The spelling variation 'Kaycee' is often seen as a more feminine version of the name, though it can be used for either gender.
