"Where did Ebonics come from?
On this point, linguists are quite divided. Some emphasize its English origins, pointing to the fact that most of the vocabulary of Ebonics is from English and that much of its pronunciation (e.g. pronouncing final th as f) and grammar (e.g. double negatives, "I don't want none") could have come from the nonstandard dialects of English indentured servants and other workers with whom African slaves interacted.
Others emphasize Ebonics' African origins, noting that West African languages often lack th sounds and final consonant clusters (e.g. past), and that replacing or simplifying these occurs both in US Ebonics and in West African English varieties spoken in Nigeria and Ghana. Moreover, they argue that the distinction made between completed actions ("He done walked") and habitual actions ("We be walkin") in the Ebonics tense-aspect system reflects their prevalence in West African language systems and that this applies to other aspects of Ebonics sentence structure.
Other linguists are drawn to the similarities between Ebonics and Caribbean Creole English varieties, for instance, the fact that both frequently drop is and are , and that both permit dropping word initial d, b, and g in tense-aspect markers (Caribbean examples include habitual/progressive (d)a, past tense (b)en, and future (g)on). These traits suggest that some varieties of American Ebonics might have undergone the kinds of simplification and mixture associated with Creole formation in the Caribbean and elsewhere. They might also suggest that American Ebonics was shaped by the high proportions of Creole-speaking slaves that were imported from the Caribbean in the earliest settlement periods of the thirteen original colonies.
Arguments about and evidence on the origins issue continue to be brought forth. A relatively new 'historical' issue has emerged in recent years: Is Ebonics converging with or diverging from other vernacular varieties of American English? One thing is for sure: This dynamic, distinctive variety--thoroughly intertwined with African American history and linked in many ways with African American literature, education, and social life--is one of the most extensively studied and discussed varieties of American English and it will probably continue to be so for many years to come."
