A particular twenty-first-century understanding of the Aztec concept "nepantla," one which has recently taken hold in critical education thanks to the writings of Gloria Anzaldúa, does not accurately reflect traditional Aztec history and philosophy.

It then asks education researchers and practitioners to instead use the theoretical framework of "malinalli," the Aztec philosophical concept which best aligns with transformative social justice goals.
