Why can't i get a fucking definition of 'subjecthood'?

I've been jabbed

How do Cather, Faulkner, or Momaday use the conventions of regionalism—e.g., focus on setting, thick description of local manners and traditions, attention to subjects typically sidelined (e.g., according to race, class, and/or gender) by more conventionally “national” or “universal” narratives—to challenge conceptions of American subjecthood constructed through Eurocentric realist and romantic traditions?
