This paper aims to consider some semantic aspects of the phenomenon of hermeneutical injustice overlooked in recent literature. First, we examine different cases of hermeneutical injustices and we propose to classify them according to their semantic structure. The core of this classification lies in the distinction between cases related to problems of content and cases related to problems of circulation of social concepts. Second, we criticize a semantic conception, implicit in much of the literature concern- ing hermeneutical injustice, according to (...) which concepts are mere labels. We show that this conception cannot provide an adequate understanding of the different cases of hermeneutical injustice that we identify: first, because it fails to capture the dynamics of conceptual change or refinement that these cases involve and, second, because it leads to diagnosing them as mere problems of concept application.
