By some accounts, there are as many as 500 languages currently used in Africa's most populous country. Several major languages are used as regional bridge languages, but everyone also speaks English, which is the sole official language.
Many Nigerians are quite fluent in English, having learned it from a young age in school. Even those who have not had any formal education can speak Nigeria's informal English, sometimes called Nigerian Pidgin English, which has lots in common with the local dialects spoken in the anglophone Caribbean. English-speaking tourists can introduce themselves to urban Africa in the booming mega-city of Lagos or explore the wildlife-filled lands of Yankari National Park without using a phrasebook.
