The term intersectionality references the critical insight that race, class, gender, sexuality, ethnicity, nation, ability, and age operate not as unitary, mutually exclusive entities, but rather as reciprocally constructing phenomena. Despite this general consensus, definitions of what counts as intersectionality are far from clear. In this article, I analyze intersectionality as a knowledge project whose raison d'être lies in its attentiveness to power relations and social inequalities. I examine three interdependent sets of concerns: ( a ) intersectionality as a field of study that is situated within the power relations that it studies; ( b ) intersectionality as an analytical strategy that provides new angles of vision on social phenomena; and ( c ) intersectionality as critical praxis that informs social justice projects.
