Chechen language
Chechens in Jordan have good relations with the Hashemite Kingdom of Jordan and are able to practice their own culture and language. Chechen language usage is strong among the Chechen community in Jordan. Chechens are bilingual in both Chechen and Arabic, but do not speak Arabic among themselves, only speaking Chechen to other Chechens. Some Jordanians are literate in Chechen as well, having managed to read and write to people visiting Jordan from Chechnya.
Pechenegs
Mahmud al-Kashgari, an 11th-century man of letters specialized in Turkic dialects argued that the language spoken by the Pechenegs was a variant of the Cuman and Oghuz idioms. He suggested that foreign influences on the Pechenegs gave rise to phonetical differences between their tongue and the idiom spoken by other Turkic peoples. Anna Komnene likewise stated that the Pechenegs and the Cumans shared a common language. Although the Pecheneg language itself died out centuries ago, the names of the Pecheneg "provinces" recorded by Constantine Porphyrogenitus prove that the Pechenegs spoke a Turkic language. The Huns, Khazars and Pechenegs are thought to have belonged to the same proto-Turkic group of languages as the modern Chuvash language (Oghur dialects).
