About the name Caio

Caio comes from the Latin Caius, a variant of Gaius, an ancient Roman given name. Behind the Name considers the meaning of Gaius uncertain: it perhaps comes from the Latin gaudeo, 'to rejoice', or from an unknown Etruscan origin; Wiktionary also links it to gaudeō. Gaius appears in the New Testament, and Behind the Name lists Caio as the Portuguese and Italian form. In the 2022 Census, IBGE recorded 286,597 people named Caio, with a median age of 17. The name is almost always male and gained ground among people born in the 1990s and 2000s; Kaio, Kayo and Cayo write the same sound with K or Y.
