What is the author's style in The Unvanquished: The Corrected Text by William Faulkner?

The use of language in The Unvanquished is perhaps as important to the validity of the work as is the setting. Faulkner is able to give his white planter population the type of correct grammar and usage they certainly would have used, as the cultured, educated class. At the same time, the dialect of black slaves is produced phonetically, so that the reader is able to pronounce words as they would have actually sounded.
