Modern Greek has, in addition to Standard Modern Greek or Dimotiki, a wide variety of dialects of varying levels of mutual intelligibility, including Cypriot, Pontic, Cappadocian, Griko and Tsakonian (the only surviving representative of ancient Doric Greek). Yevanic is the language of the Romaniotes, and survives in small communities in Greece, New York and Israel. In addition to Greek, many Greeks in Greece and the Diaspora are bilingual in other languages or dialects such as English, Arvanitika/Albanian, Aromanian, Macedonian Slavic, Russian and Turkish.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What is different about the use of Greek language today as opposed to the language of the past ?
