Spivak says that the Subaltern cannot speak; if they do, they’re not subaltern any more
Subaltern refers to the voiceless. If someone from the marginalized communities are able to voice something out, then they have relative privilege and aren’t truly representative of the subaltern
And even when people from marginalized sections of the society speak, they will only be interpreted, not heard. That is, they will be understood through the lens of the hegemony.
