In America, black who speaks vernacular tend to be those who live in the impoverished inner city neighborhood filled with violence where it is considered hype to speak in what can be termed "the language of slang's" or known to some as "black English" Like any where in the world, majority of people in those neighborhoods lack education and children are not given the opportunity to school. In a case where they (children) school, the academic performance is said to be slightly below that of other children that speak Standard English.
Black English is assumed to date back to 1619 when a Dutch vessel with a cargo of 20 Africans from different nations landed in Jamestown. Upon arrival in America, the entire slaves had to learn some degree of the English vocabulary to communicate with their masters and other slaves (who had different languages). Linguists proposed that Africans developed a pigin language with the English language to make communication easier especially during "transaction and became a creolized language"( stoller, 21).
Probably as a remainder of their home land, the slaves taught their children African-English pigin which is a mixture of west African languages such as Ibo, Hausa, and Yoruba with English.
