Kartvelian languages in the context of "Caucasus"

Pontic Greek (Pontic: Ρωμαίικα, romanized: Rhomaiika, Greek: Ποντιακά, romanized: Pontiaka; Turkish: Rumca or Romeika), also referred to as Pontic, is a variety of Modern Greek indigenous to the Pontus region on the southern shores of the Black Sea, northeastern Anatolia, and the Eastern Turkish and Caucasus region. An endangered Greek language variety, Pontic Greek is spoken by about 778,000 people worldwide, who are known as Pontic or Pontian Greeks.

Like nearly all of Greek varieties spoken today, the linguistic lineage of Pontic Greek stems from the Hellenistic Koine, itself based on Attic–Ionic Greek, which later developed into the Byzantine Greek of the Middle Ages. Following its geographic isolation from the rest of the Greek–speaking world, Pontic continued to develop separately along with other Anatolian Greek dialects, like Cappadocian, from the 11th century onwards. As a result, Pontic Greek is not completely mutually intelligible with the standard Demotic Greek spoken in mainland Greece today. Pontic also contains influences from Russian, Turkish, Kartvelian (namely Laz and Georgian) and Armenian.

The Mingrelian or Megrelian language (მარგალური ნინა margaluri nina) is a Kartvelian language spoken in Western Georgia (regions of Mingrelia and Abkhazia), primarily by the Mingrelians. Mingrelian has historically been only a regional language within the boundaries of historical Georgian states and then modern Georgia, and the number of younger people speaking it has decreased substantially, with UNESCO designating it as a "definitely endangered language".

The Laz or Lazuri language (Laz: ლაზური ნენა, romanized: lazuri nena) is a Kartvelian language spoken by the Laz people on the southeastern shore of the Black Sea. In 2007, it was estimated that there were around 20,000 native speakers in Turkey, in a strip of land extending from Melyat to the Georgian border (officially called Lazistan until 1925), and around 1,000 native speakers around Adjara in Georgia. There are also around 1,000 native speakers of Laz in Germany.

Laz is not historically a written language or literary language. In 1989, Benninghaus wrote that the Laz themselves had no interest in writing in Laz.

The pre-Indo-European languages are any of several ancient languages, not necessarily related to one another, that existed in Prehistoric Europe, Asia Minor, Ancient Iran, and Southern Asia before the arrival of speakers of Indo-European languages. The oldest Indo-European language texts are Hittite and date from the 19th century BC in Kültepe (modern eastern Turkey), and while estimates vary widely, the spoken Indo-European languages are believed to have developed at the latest by the 3rd millennium BC (see Proto-Indo-European Urheimat hypotheses). Thus, the pre-Indo-European languages must have developed earlier than or, in some cases, alongside the Indo-European languages that ultimately displaced and replaced almost all of them.

A handful of the pre-Indo-European languages are still extant: in Europe, Basque retains a localised strength, with fewer than a million native speakers, whereas the Dravidian languages remain very widespread in the Indian subcontinent, with over 250 million native speakers (the four major languages being Telugu, Tamil, Kannada and Malayalam) and the Brahui that stretches into modern Iran. In the Caucasus, Northwest and Northeast Caucasian languages and Kartvelian languages are still intact, with the first having the least language security of the three pre-Indo-European Caucasian language groups. Some pre-Indo-European languages are attested only as linguistic substrates in Indo-European languages or in toponyms. In much of Western Asia (including Iran and Anatolia), the pre-Indo-European, Hurrian/Caucasian, Semitic languages, Dravidian and language isolates have survived to the present day, although Elamite has entirely disappeared.

The Georgian scripts are the three writing systems used to write the Georgian language: Asomtavruli, Nuskhuri and Mkhedruli. Although the systems differ in appearance, their letters share the same names and alphabetical order and are written horizontally from left to right. Of the three scripts, Mkhedruli, once the official script of the Kingdom of Georgia and mostly used for the royal charters, is now the standard script for modern Georgian and its related Kartvelian languages, whereas Asomtavruli and Nuskhuri are used only by the Georgian Orthodox Church, in ceremonial religious texts and iconography.

Georgian scripts are unique in their appearance and their exact origin has never been established; however, in strictly structural terms, their alphabetical order largely corresponds to the Greek alphabet, with the exception of letters denoting uniquely Georgian sounds, which are grouped at the end. Originally consisting of 38 letters, Georgian is presently written in a 33-letter alphabet, as five letters are obsolete. The number of Georgian letters used in other Kartvelian languages varies. Mingrelian uses 36: thirty-three that are current Georgian letters, one obsolete Georgian letter, and two additional letters specific to Mingrelian and Svan. Laz uses the same 33 current Georgian letters as Mingrelian plus that same obsolete letter and a letter borrowed from Greek for a total of 35. The fourth Kartvelian language, Svan, is not commonly written, but when it is, it uses Georgian letters as utilized in Mingrelian, with an additional obsolete Georgian letter and sometimes supplemented by diacritics for its many vowels.

The Zan languages, or Zanuri (Georgian: ზანური ენები) or Colchidian, are a branch of the Kartvelian languages constituted by the Mingrelian and Laz languages. The grouping is disputed as some Georgian linguists consider the two to form a dialect continuum of one Zan language. This is often challenged on the most commonly applied criteria of mutual intelligibility when determining borders between languages, as Mingrelian and Laz are only partially mutually intelligible, though speakers of one language can recognize a sizable amount of vocabulary of the other, primarily due to semantic loans, lexical loans and other areal features resulting from geographical proximity and historical close contact common for dialect continuums.

The term Zan comes from the Greco-Roman name of one of the chief Colchian tribes, which is almost identical to the name given to the Mingrelians by the Svans (მჷ-ზა̈ნ mə-zän). Georgian linguist Akaki Shanidze proposed the name "Colchidian" for Zan.
