Bulgar (also spelled Bolğar, Bulghar) is an extinct language which was spoken by the Bulgars. Many scholars believe that it belonged to Oghur subgroup of Turkic languages, however its precise roots have not been conclusively proven due to extremely limited written record.
It is named for the Bulgars, a tribal association which established the Bulgar khanate, known as Old Great Bulgaria in the mid-7th century, giving rise to the Danubian Bulgaria by the 680s. While the language was extinct in Danubian Bulgaria (in favour of the Slavic Bulgarian language), it persisted in Volga Bulgaria, eventually giving rise to the modern Chuvash language.
Mainstream scholarship place the Bulgar language among the "Lir" branch of Turkic languages referred to as Oghur-Turkic, Lir-Turkic, or, indeed, "Bulgar Turkic" as opposed to the "Shaz"-type of Common Turkic. The "Lir" branch is characterized by sound correspondences such as Oghuric r versus Common Turkic (or Shaz-Turkic) z and Oghuric l versus Common Turkic (Shaz-Turkic) š. As was stated by Al-Istakhri "the language of Bulgars resembles the language of Khazars". The only surviving language from this linguistic group is the Chuvash.
On the other hand, some Bulgarian historians, especially modern ones, link the Bulgar language to the Iranian language group instead (more specifically, the Pamir languages are frequently mentioned), noting the presence of Iranic words in the modern Bulgarian language. According to Prof. Raymond Detrez, who is a specialist in Bulgarian history and language, such views have an ideological motivation. However, other Bulgarian historians, especially older ones, only point out certain signs of Iranian influence in the Turkic base, or indeed support the Turkic theory.
Danube Bulgar 
The language of the Danube Bulgars (or Danube Bulgar) is recorded in a small number of inscriptions, which are found in Pliska, the first capital of Danube Bulgaria and in the rock churches near the village of Murfatlar, present-day Romania. Some of these inscriptions are written with Greek characters, others with runes similar to the Orkhon script. Most of them appear to have a private character (oaths, dedications, inscriptions on grave stones) and some were court inventories. Although attempts at decipherment have been made, none of them has gained wide acceptance. These inscriptions in Danube-Bulgar are found along with other official ones written in Greek. Greek was used as the official state language of Danube Bulgaria until the 9th century, when it was replaced by Old Bulgarian (Slavonic).
The language of the Danube Bulgars is also known from a small number of loanwords in the Old Bulgarian language, as well as terms occurring in Bulgar Greek-language inscriptions, contemporary Byzantine texts, and later Slavonic Old Bulgarian texts. Most of these words designate titles and other concepts concerning the affairs of state, including the official 12-year cyclic calendar (as used e.g. in the Nominalia of the Bulgarian Khans). The language became extinct in Danubian Bulgaria in the 9th century as the Bulgar nobility became gradually Slavicized after the Old Bulgarian was declared as official in 893.
Volga Bulgar 
The language spoken by the population of Volga Bulgaria is known as Volga-Bulgar. There are a number of surviving inscriptions in Volga-Bulgar, some of which are written with Arabic letters, alongside the continuing use of Turkic runes. These are all largely decipherable. That language persisted until the 13th or the 14th century. In that region, it may have ultimately given rise to the Chuvash language, which is most closely related to it and which is classified as the only surviving member of a separate "Oghur-Turkic" (or Lir-Turkic) branch of the Turkic languages, to which Bulgar is also considered to have belonged (see above). Still, the precise position of Chuvash within the Oghur family of languages is a matter of dispute among linguists. Since the comparative material attributable to the extinct members of Oghuric (Hunnic, Turkic Avar, Khazar and Bulgar) is scant, little is known about any precise interrelation of these languages and it is a matter of dispute whether Chuvash, the only "Lir"-type language with sufficient extant linguistic material, might be the daughter language of any of these or just a sister branch.
