Poplack and other contributors to this important volume are to be commended for an exceptionally well crafted book, with a succession of groundbreaking studies of African American English (AAE). Although this work will undoubtedly add fuel to the flames of historical linguistic controversy that continue to swirl around African Americans, Poplack and her colleagues go far to advance hypotheses and analyses that argue in favor of the English origins of African American Vernacular English (AAVE).
