Purpose: By engaging in critical literacy, participants theorized Blackness and antiblackness. The purpose of this study was to have participants theorize Blackness and antiblackness through their engagements with critical literacy. Design/methodology/approach: The authors used a youth-centered and informed Black critical-race grounded methodology. Findings: Participants' unique and varied revelations of Blackness as Vitality, Blackness as Cognizance and Blackness as Expansive Community, served to withstand, confront and transcend encounters with antiblackness in English curricula. Practical implications: This paper provides a model for how to engage Black youth as a means to disrupt anti-Black English education spaces. Social implications: This study provides a foundation for future research efforts of Black English outer spaces as they relate to English education. Findings in this study may also inform existing English educator practices. Originality/value: This study theorized both the role and the flexible nature of Black English outer spaces. It defined the multi-ethnic nature of Blackness. It proposed that affirmations of Blackness sharpened participants' critical literacies in Black English outer spaces as a transformative intervention to anti-Black English education spaces.
