Unknown; possibly a modern blend or variant of Anthony
Antario is a rare modern American name. It is likely a creative elaboration of the name Anthony, influenced by the 'O' ending found in names like Antonio or Mario. Because it lacks a distinct historical etymology, it is often chosen for its rhythmic, melodic sound rather than a specific traditional meaning.
