The main and official language of Greece is Modern Greek. Moreover, there are some minority languages: There are some Hellenic dialects that are so different from mainstream Greek that they qualify as distinct languages, notably Tsakonian. Modern Greek dialects all derive from Koine or the Common Dialect, the mixture of earlier Greek dialects that came into being as a result of Alexander the Great's exploits. Tsakonian is based on a dialect that existed before Alexander. This is why it is drastically different from Koine-based modern Greek.
