Nigerian Standard English, or simply Nigerian English, is a form of English spoken in Nigeria. It is most commonly spoken in urban areas, particularly in Lagos. It is based on British English, but in recent years, because of increasing contact with the United States, some words of American English origins have made it into Nigerian English.[which?] Additionally, some new words and collocations have emerged from the language, which come from the need to express concepts specific to the culture of the nation (e.g. bride-price, senior wife).
Nigerian Pidgin, a pidgin derived from English, is more used in informal conversations than Nigerian English, although Nigerian Standard English is used in politics, the media, and other official uses.
