Conceptual ethics concerns a range of issues about the normative and evaluative assessment of concepts and words. It includes, centrally, the assessment of which concepts a given agent should use (in a given context), and the assessment of which words an agent should use (in a given context) to express those concepts. In this paper, we address the conceptual ethics of normative inquiry. We understand normative inquiry in broad terms. It encompasses inquiry into what agents should do, think, or feel, and into what should or ought to be the case.
