many of the 250 or more ethnic groups in nigeria can converse in the language, though they usually have their own additional words. for example, the yorùbás use the words "ṣebi" and "abi" when speaking pidgin. they are often used at the start or end of an intonated sentence or question: "you are coming, right?" becomes "ṣebi you dey come?" or "you dey come abi?"
