Greek (ελληνικά, IPA: [eliniˈka] or ελληνική γλώσσα, IPA: [eliniˈci ˈɣlosa]), an independent branch of the Indo-European family of languages, is the language of the Greeks. Native to the southern Balkans, it has the longest documented history of any Indo-European language, spanning 34 centuries of written records. In its ancient form, it is the language of classical ancient Greek literature and the New Testament of the Christian Bible. It has been spoken as the major language of the Ancient Classical World, and it then became the official language of the Eastern Roman or Byzantine Empire. In its modern form, it is the official language of Greece and Cyprus and one of the 23 official languages of the European Union. Spoken by approximately 13 million people inside Greece, including minority and emigrant communities worldwide in numerous parts of the world, its written form uses the Greek alphabet. Many modern languages, such as the English language, have adopted words from Greek. The English language has over 50,000 words in its lexicon which are derived from the Greek language, especially in the arts of the Sciences, Medicine, and other fields of studies and literature.
