Later, linguists debated among themselves, often acrimoniously, the relationships between black and white speech and the origins of BEV.2 In spite of the long and bitter polemics that developed during these latter stages, by 1982 William Labov, in the wake of the Ann Arbor decision, was able to assert that a consensus on BEV had emerged. Most linguists, he suggested, agreed that BEV is a subsystem of English which, although incorporating many features of Southern States English, has a distinct set of phonological and syntactic rules. Those rules are now aligned in many ways with the rules of other dialects but still show evidence of derivation from an earlier
