This study examines how 9- to 13-year old African American students in a Washington, D.C. after-school program use an African American discourse practice called marking to voice adults performing acts of discipline. Using audio-recorded data collected during nine months of ethnographic fieldwork, it shows how students used marking to resemiotize the prestige value of African American Language (AAL) relative to so-called “standard” American English, which is imagined in relation to whiteness as an objectively correct set of linguistic practices. As part of an intersectional raciolinguistic perspective, this study foregrounds how students recruit gender stereotypes to challenge hegemonic ideas about racial and linguistic difference. It also attends to the contradictory nature of everyday acts of resistance: while students transformed hegemonic raciolinguistic ideologies of “articulate” and “appropriate” language in the after school space, they relied on racial and gender stereotypes in order to do so.
