About the name Mário

Mário is a learned borrowing from Latin Marius, according to Wiktionary, which also records the folk etymology that sees it as the masculine of Maria. The origin of Marius is uncertain: Behind the Name derives it from Mars, the Roman god of war, or from the Latin root mas, maris, 'male', and Wiktionary links it to an Oscan praenomen, probably of Sabine origin. The Dicionário de Nomes em Uso no Brasil (Dictionary of Names in Use in Brazil), citing Machado (1981), gives it as a Roman family name. In the 2022 Census, IBGE recorded 225,399 people named Mário, almost always men, with a median age of 53.
