Romanization of Greek is a way to write the Greek language (either Ancient or modern Greek) with the Roman alphabet. This can either be done by mapping letters (called transliteration) or by mapping sounds (called transcription. The greek name Ἰωάννης can be transliterated as Johannes, which became John, in Modern English. In modern Greek, it is generally written Γιάννης, which transliterates to Yannis. The masculine Greek word Ἅγιος or Άγιος might variously appear as Hagiοs, Agios, Aghios, or Ayios, or simply be translated as "Holy" or "Saint" in English forms of Greek placenames.
