Pronunciation

KAH-yohListen

Cayo comes from Spanish, where it developed as a surname equivalent of Gaetano, tracing back to the Latin Caietanus — literally 'man from Gaeta,' a town in Italy. You may come across the idea that it means 'small island' or 'cay,' which is indeed a real Spanish word and probably part of why the name feels so fresh today, but that's not actually where the name comes from. Its roots run through that Italian place name by way of a Spanish surname.

Meaning & Origin of Cayo

Meaning: Man from Gaeta (a town in Italy).

Origin: Spanish (surname, equivalent of Gaetano, from Latin Caietanus).

A common claim: Cayo is sometimes thought to mean 'small island / cay' in Spanish. Actually: That's the everyday Spanish word cayo, and a plausible reason for the name's current appeal. But Wiktionary traces the name itself to the surname equivalent of Gaetano, meaning 'from Gaeta' — a separate origin.
