"Variant of Antonius"
The name Antonios is commonly a male name from the "Swedish" origin.
Antonios is the Greek form of the Latin family name Antonius, the name of the Roman gens Antonia. Greek uses it as the equivalent of the English name Anthony, and it is attested in Greek inscriptions and texts from the Roman period onward. The derivation of the Latin Antonius itself is not settled, so no meaning is assigned to it here.
Antonius means "Worth of praise, Priceless.".
The pronunciation of Antonios is an-TOH-nee-ohs.
