The number of languages currently estimated and catalogued in Nigeria is 521. This number includes 510 living languages, two second languages without native speakers and nine extinct languages. In some areas of Nigeria, ethnic groups speak more than one language. The official language of Nigeria, English, was chosen to facilitate the cultural and linguistic unity of the country. The choice of English as the official language was partially related to the fact that a part of the Nigerian population spoke English as a result of British colonization that ended in 1960.
The major languages spoken in Nigeria represent three major families of African languages – the majority are Niger-Congo languages, such as Yoruba, Igbo, the Hausa language is Afro-Asiatic; and Kanuri, spoken in the northeast, primarily Borno State, is a member of the Nilo-Saharan family. Even though most ethnic groups prefer to communicate in their own languages, English, being the official language, is widely used for education, business transactions and for official purposes. English as a first language, however, remains an exclusive preserve of a small minority of the country's urban elite, and it is not spoken at all in some rural areas. With the majority of Nigeria's populace in the rural areas, the major languages of communication in the country remain indigenous languages. Some of the largest of these, notably Yoruba and Igbo, have derived standardized languages from a number of different dialects and are widely spoken by those ethnic groups. Nigerian Pidgin English, often known simply as 'Pidgin' or 'Broken' (Broken English), is also a popular lingua franca, though with varying regional influences on dialect and slang. The pidgin English or Nigerian English is widely spoken within the Niger Delta Regions, predominately in Warri, Sapele, Port Harcourt, Agenebode, Ewu, and Benin City.
