Greek (ελληνική γλώσσα or simply ελληνικά — "Hellenic") is one of the earliest attested Indo-European languages (with fragmentary records in Mycenaean dating back to the 15th or 14th century BC), spoken today by 15-22 million people, mainly in Greece and Cyprus but also by minority and emigrant communities in numerous other countries.
Greek has been written in the Greek alphabet since the 9th century BC in Greece (before that in Linear B), and the 4th century BC in Cyprus (before that in Cypriot syllabary). Greek literature has a continuous history of nearly three thousand years.
Greek is the official language of Greece where it is spoken by about 99.5% of the population. It is also (nominally alongside Turkish), the official language of Cyprus. Because of the membership of Greece and Cyprus in the European Union, Greek is one of the 23 official languages of the European Union. Greek is officially recognized as a minority language in parts of Turkey, Italy and Albania.
