There are over 520 native languages spoken in Nigeria. The official language is English, which was the language of Colonial Nigeria. The English-based creole Nigerian Pidgin – first used by the British and African slavers to facilitate the Atlantic slave trade in the late 17th century – is the most common lingua franca, spoken by over 60 million people.
The most commonly spoken native languages are Hausa (over 63 million when including second-language, or L2, speakers), Yoruba (over 47 million, including L2 speakers), Igbo (over 46 million, including L2 speakers), Ibibio (over 10 million, including L2 speakers), Ijaw cluster (over 5 million), Fulfulde (18 million), Kanuri (7.6 million), Tiv (5 million), and approximately 2 to 3 million each of Nupe, Karai-Karai, Kupa, Kakanda, Edo, Igala, Mafa, Idoma and Efik. Nigeria's linguistic diversity is a microcosm of much of Africa as a whole, and the country contains languages from the three major African language families: Afroasiatic, Nilo-Saharan and Niger-Congo. Nigeria also has several as-yet unclassified languages, such as Centúúm, which may represent a relic of an even greater diversity before the spread of the current language families.
