Caius Origin and Meaning

The name Caius is a boy's name of Latin origin meaning "rejoice".

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.

My mother thinks Caius sounds feminine (now that's what I call an unpopular opinion). Berries, what do you think? Caius on a girl?!

My son is called Caius and we pronounce it "ky-uss". He has just turned 2 years old. A lot of people mispronounce it "Kay-us" and spell it Cauis. It doesn't bother me too much anymore. We call him Cai for short. I love his name regardless of how weird people think it is!

I really like Caius. It's one of the few majestic-sounding Latinate names in -us which I can actually see working on a modern boy/man. Cai would fit right in with his classmates.

I love this name so much. Cai would be a really cool nickname. It has Christian heritage without being too blatant like Isaiah or Samuel.

Kai-us, though Kay-us is just as good. Originally, it was pronounced like Gaius (Cs and Gs were the same), which has two common pronunciations (Guy-us and Gay-us). The "ai" in Latin is pronounced ah-ee and "u" is oo. So, you could say the original is somewhat like Kah-ee-oo-s, which just sounds like an elongated way to get to "kai-us."

I love this name but it's starting to sound "callous" to me.
