The Greek language with a documented record spanning three and a half millennia is a strong element of national continuity. Modern Greek derives from the same idiom used by Homer. Greek is also the language of the Gospels. The Greek alphabet and the Greek language have contributed much to all western languages. Today's Greeks, however, are the only ones who ensure this linguistic continuity. In this respect Greek, is to be distinguished sharply from Latin which generated numerous neo-latin languages from Rumanian to Portuguese before it became itself extinct.
