Greek (Modern Greek: ελληνικά elliniká) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus and other parts of the Eastern Mediterranean and the Black Sea. It has the longest documented history of any living Indo-European language, spanning more than 3000 years of written records. Its writing system has been the Greek alphabet for the major part of its history; other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems.
The Greek language holds an important place in the history of the Western world and Christianity; the canon of ancient Greek literature includes works in the Western canon such as the epic poems Iliad and Odyssey. Greek is also the language in which many of the foundational texts in science, especially astronomy, mathematics and logic and Western philosophy, such as the Platonic dialogues and the works of Aristotle, are composed; the New Testament of the Christian Bible was written in Koiné Greek. Together with the Latin texts and traditions of the Roman world, the study of the Greek texts and society of antiquity constitutes the discipline of Classics.
During antiquity, Greek was a widely spoken lingua franca in the Mediterranean world, West Asia and many places beyond. It would eventually become the official parlance of the Byzantine Empire and develop into Medieval Greek. In its modern form, Greek is the official language in two countries, Greece and Cyprus, a recognised minority language in seven other countries, and is one of the 24 official languages of the European Union. The language is spoken by at least 13.2 million people today in Greece, Cyprus, Italy, Albania, and Turkey and by the Greek diaspora.
Greek roots are often used to coin new words for other languages; Greek and Latin are the predominant sources of international scientific vocabulary.
Idealised portrayal of Homer
Greek has been spoken in the Balkan peninsula since around the 3rd millennium BC, or possibly earlier. The earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the world's oldest recorded living language. Among the Indo-European languages, its date of earliest written attestation is matched only by the now-extinct Anatolian languages.
The Greek language is conventionally divided into the following periods:
- Proto-Greek: the unrecorded but assumed last ancestor of all known varieties of Greek. The unity of Proto-Greek would have ended as Hellenic migrants entered the Greek peninsula sometime in the Neolithic era or the Bronze Age.
- Mycenaean Greek: the language of the Mycenaean civilisation. It is recorded in the Linear B script on tablets dating from the 15th century BC onwards.
- Ancient Greek: in its various dialects, the language of the Archaic and Classical periods of the ancient Greek civilisation. It was widely known throughout the Roman Empire. Ancient Greek fell into disuse in western Europe in the Middle Ages, but remained officially in use in the Byzantine world and was reintroduced to the rest of Europe with the Fall of Constantinople and Greek migration to western Europe.
- Koine Greek: The fusion of Ionian with Attic, the dialect of Athens, began the process that resulted in the creation of the first common Greek dialect, which became a lingua franca across the Eastern Mediterranean and Near East. Koine Greek can be initially traced within the armies and conquered territories of Alexander the Great and after the Hellenistic colonization of the known world, it was spoken from Egypt to the fringes of India. After the Roman conquest of Greece, an unofficial bilingualism of Greek and Latin was established in the city of Rome and Koine Greek became a first or second language in the Roman Empire. The origin of Christianity can also be traced through Koine Greek, because the Apostles used this form of the language to spread Christianity. It is also known as Hellenistic Greek, New Testament Greek, and sometimes Biblical Greek because it was the original language of the New Testament and the Old Testament was translated into the same language via the Septuagint.
- Medieval Greek, also known as Byzantine Greek: the continuation of Koine Greek, up to the demise of the Byzantine Empire in the 15th century. Medieval Greek is a cover phrase for a whole continuum of different speech and writing styles, ranging from vernacular continuations of spoken Koine that were already approaching Modern Greek in many respects, to highly learned forms imitating classical Attic. Much of the written Greek that was used as the official language of the Byzantine Empire was an eclectic middle-ground variety based on the tradition of written Koine.
- Modern Greek (Neo-Hellenic): Stemming from Medieval Greek, Modern Greek usages can be traced in the Byzantine period, as early as the 11th century. It is the language used by the modern Greeks, and, apart from Standard Modern Greek, there are several dialects of it.
In the modern era, the Greek language entered a state of diglossia: the coexistence of vernacular and archaizing written forms of the language. What came to be known as the Greek language question was a polarization between two competing varieties of Modern Greek: Dimotiki, the vernacular form of Modern Greek proper, and Katharevousa, meaning 'purified', a compromise between Dimotiki and Ancient Greek, which was developed in the early 19th century and was used for literary and official purposes in the newly formed Greek state. In 1976, Dimotiki was declared the official language of Greece, having incorporated features of Katharevousa and giving birth to Standard Modern Greek, which is used today for all official purposes and in education.
The distribution of major modern Greek dialect areas
The historical unity and continuing identity between the various stages of the Greek language is often emphasised. Although Greek has undergone morphological and phonological changes comparable to those seen in other languages, never since classical antiquity has its cultural, literary, and orthographic tradition been interrupted to the extent that one can speak of a new language emerging. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than a foreign language. It is also often stated that the historical changes have been relatively slight compared with some other languages. According to one estimation, "Homeric Greek is probably closer to demotic than 12-century Middle English is to modern spoken English," (Greek has seen fewer changes in 2700 years than English has in 900 years).
