the mass media and in political slogans. According to a 2012 study, the replacement of native local languages with Pidgin is inevitable in the areas studied. Afroasiatic languages The Afroasiatic languages of Nigeria are divided into Chadic, Semitic and Berber. Among these category, Chadic languages predominate, with more than 700 languages. Semitic is represented by various dialects of Arabic spoken in the Northeast and Berber by the Tuareg-speaking communities in the extreme Northwest. The Hausa language is the best known Chadic language in Nigeria; though there is a paucity of statistics on native speakers in Nigeria, the language is spoken by 24 million people in West Africa and is the second language of 15 million more. Hausa has therefore emerged as lingua franca throughout much of West Africa, and the Sahel in particular. The language is spoken primarily amongst Northern Nigerians and is often associated with Islamic culture in Nigeria and West Africa on the whole. Hausa is classified as a West Chadic language of the Chadic grouping, a major subfamily of Afroasiatic. Culturally, the Hausa people became closely integrated with the Fulani following the establishment of the Sokoto Caliphate by the Fulani Uthman dan Fodio in the 19th century. Hausa is the official language of several states in Northern Nigeria and the most important dialect is generally regarded as that spoken in Kano, an Eastern Hausa dialect, which is the standard variety used for official purposes. Eastern dialects also include some dialects spoken in Zaria and Bauchi; Western Hausa dialects include Sakkwatanchi spoken in Sokoto, Katsinanchi in Katsina Arewanchi in both Gobir and Adar, Kebbi and Zamfara. Katsina is transitional between Eastern and Western dialects. Northern Hausa dialects include Arewa and Arawa, whilst Zaria is a prominent Southern version; Barikanchi is a pidgin formerly used in the military. Hausa is a very atypical Chadic language, with a reduced tonal system and a phonology influenced by Arabic. Other well-known Chadic languages include Mupun, Ngas, Goemai, Mwaghavul, Bole, Ngizim, Bade and Bachama. In the East of Nigeria and on into Cameroon are the Central Chadic languages such as Bura, Kamwe and Margi. These are highly diverse and remain very poorly described. Many Chadic languages are severely threatened; recent searches by Bernard Caron for Southern Bauchi languages show that even some of those recorded in the 1970s have disappeared. However unknown Chadic languages are still being reported, such as the recent description
