Intersectionality (or Intersectionalism) is the study of intersections between different disenfranchised groups or groups of minorities; specifically, the study of the interactions of multiple systems of oppression or discrimination. The term is particularly prevalent in black feminism, which argues that the experience of being a black female cannot simply be understood in terms of being black, and of being female, considered independently, but must include the interactions, which frequently reinforce each other.
The context was considering the interactions between being female and being a software engineer.
