Where the Cariello surname comes from
Scholars disagree about where Cariello comes from. There are two serious theories, both born from the everyday speech of ordinary people in the South.
The first leads to an old personal name, Carellus, an affectionate form used in the Middle Ages: Cariello would then mean “Carello’s son.” The second leads to the dialect word carriello, the “little cart”: a nickname for someone who built, drove or owned a cart. Either way, it is a surname born among the people of the Mezzogiorno.
