Hellenic languages in the context of "Greek (language)"

Greek (Modern Greek: ελληνικά, romanized: elliniká [eliniˈka] ; Ancient Greek: ἑλληνική, romanized: hellēnikḗ [helːɛːnikɛ́ː]) is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family. It is native to the territories that have had populations of Greeks since antiquity: Greece, Cyprus, Egypt, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary.

The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts in science and philosophy were originally composed. The New Testament of the Christian Bible was also originally written in Greek. Together with the Latin texts and traditions of the Roman world, the Greek texts and Greek societies of antiquity constitute the objects of study of the discipline of Classics.

There are over 250 languages indigenous to Europe, and most belong to the Indo-European language family. Out of a total European population of 744 million as of 2018, some 94% are native speakers of an Indo-European language. The three largest phyla of the Indo-European language family in Europe are Romance, Germanic, and Slavic; they have more than 200 million speakers each, and together account for close to 90% of Europeans.

Smaller phyla of Indo-European found in Europe include Hellenic (Greek, c. 13 million), Baltic (c. 4.5 million), Albanian (c. 7.5 million), Celtic (c. 4 million), and Armenian (c. 4 million). Indo-Aryan, though a large subfamily of Indo-European, has a relatively small number of languages in Europe, and a small number of speakers (Romani, c. 1.5 million). However, a number of Indo-Aryan languages not native to Europe are spoken in Europe today.

The Indo-European languages are a language family native to the northern Indian subcontinent, most of Europe, and the Iranian plateau, with additional native branches found in regions such as parts of Central Asia (e.g., Tajikistan and Afghanistan), southern Indian subcontinent (Sri Lanka and the Maldives) and Armenia. Historically, Indo-European languages were also spoken in Anatolia and Northwestern China. Some European languages of this family—English, French, Portuguese, Italian, Russian, Spanish, and Dutch—have expanded through colonialism in the modern period and are now spoken across several continents. The Indo-European family is divided into several branches or sub-families, including Albanian, Armenian, Balto-Slavic, Celtic, Germanic, Hellenic, Indo-Iranian, and Italic, all of which contain present-day living languages, as well as many more extinct branches.

Today the individual Indo-European languages with the most native speakers are English, Spanish, Portuguese, Russian, Hindustani, Bengali, Punjabi, French, and German; many others spoken by smaller groups are in danger of extinction. Over 3.4 billion people (42% of the global population) speak an Indo-European language as a first language—by far the most of any language family. There are about 446 living Indo-European languages, according to an estimate by Ethnologue, of which 313 belong to the Indo-Iranian branch.

Graeco-Aryan, or Graeco-Armeno-Aryan, is a hypothetical clade within the Indo-European family that would be the ancestor of Hellenic, Armenian, and the Indo-Iranian languages, which spans Southern Europe, Armenian highlands and Southern Asian regions of Eurasia.

The Graeco-Armeno-Aryan group supposedly branched off from the parent Indo-European stem by the mid-3rd millennium BC.

The Proto-Greek language, also known as Proto-Hellenic, is the Indo-European language which was the last common ancestor of all varieties of Greek, including Mycenaean Greek, the subsequent ancient Greek dialects (i.e., Attic, Ionic, Aeolic, Doric proper, Arcadocypriot, Northwest Greek, ancient Macedonian—either a dialect or a closely related Hellenic language) and, ultimately, Koine, Byzantine and Modern Greek (along with its variants). Proto-Greek speakers entered Greece sometime between 2200 and 1900 BC, with the diversification into a southern and a northern group beginning by approximately 1700 BC.

The Kurgan hypothesis (also known as the Kurgan theory, Kurgan model, or steppe theory) is the most widely accepted proposal to identify the Proto-Indo-European homeland from which the Indo-European languages spread out throughout Europe and parts of Asia. It postulates that the people of a Kurgan culture in the Pontic steppe north of the Black Sea were the most likely speakers of the Proto-Indo-European language (PIE). The term is derived from the Turkic word kurgan (курга́н), meaning tumulus or burial mound.

The steppe theory was first formulated by Otto Schrader (1883) and V. Gordon Childe (1926), then systematized in the 1950s by Marija Gimbutas, who used the term to group various prehistoric cultures, including the Yamnaya (or Pit Grave) culture and its predecessors. In the 2000s, David Anthony instead used the core Yamnaya culture and its relationship with other cultures as a point of reference.
