Abstract: Henry Louis Gates, Jr. gives a groundbreaking in the unique interpretative system and the great vernacular tradition of African-American literary criticism—the Signifying Theory, which provides a methodology and perspective in African-American literary criticism within the tradition of Black Vernacular. From the critical perspective of Signifying Theory, this paper analyzes the text of Erasure, representative work of African-American writer Percival Everett. Not only the story's whole narrative structure comprises of signifying revision of its sub-text Fuck, but the rhetorical strategies are embodied with the black difference. As a result, the novel is infiltrated with sharp satire profoundly. Also it reflects the nature of “blackness”, an important concept in Gates' Signifying Theory.
