Gender: M Meaning of Caius: "rejoice" Origin of Caius: Latin

Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys. Caius is currently Number 164 on Nameberry.

Nickname Cai is a definite asset.
