"to rejoice"

Gaius Origin and Meaning

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

Stately Gaius (pronounced GUY-us) was in the name of many ancient Romans, including Julius Caesar. Little-used before the year 2000, it now feels like a fresh possibility in the revival of Latin boys' names like Atticus and Cassius. Caius and derivatives like Caio come from the same root, and in ancient Roman times Caius was probably pronounced as Gaius. You could also see Gaius as a male version of the earth-goddess name Gaia.
