Greek
Greek 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. Its writing system for the majority of its history has the Greek alphabet (though other systems, such as Linear B and the Cypriot syllabary, were previously used). The alphabet arose from the Phoenician script, and was in turn the basis of the Latin, Cyrillic, Coptic, and many other writing systems.

Greek was a widely spoken lingua franca in the Mediterranean world and beyond during Classical Antiquity, and would eventually become the official parlance of the 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. The language is spoken by approximately 13 million people today in Greece, Cyprus, and diaspora communities in numerous parts of the world. Many modern languages, such as English, have adopted words from Greek. English has over 50,000 words in its lexicon which are derived from the Greek language, especially in the sciences and medicine.
