This article argues that linguistically endangered minority groups often face endangerment due to structural linguistic injustice that arises from past injustices and ongoing unjust social processes. Language revitalization is often a justified way of reforming unjust social structures. I connect this discussion to another debate, namely, whether historical injustice (and the requirement for its correction) may be superseded. I ask: which changing circumstances might lead to the supersession of structural linguistic injustice? Of the many reasons to reform unjust social structures, (...) I focus on dignity-based concerns. Historically-sensitive dignity-based concerns are relevant for judging whether supersession of structural linguistic injustice has occurred. My view is largely present-oriented, but history still plays a role in deciding the strength of justificatory bases for structural reformation. (shrink)
