Abstract In recent years, scholars have vividly debated over the definition and features of dogwhistles. As Jennifer Saul has widely argued in her works, political dogwhistles are powerful tools of manipulation. However, the current debate still lacks a convincing definition of dogwhistles, which sometimes are treated like spy codes while, at other times, they are labelled as instances of hate speech, as in Santana (2019). Instead, I propose a definition of dogwhistles that is based on the analysis of the audience design of utterances. I claim that dogwhistles are speech acts designed to secretly change the conversational role of a subset of the audience. Furthermore, they qualify as forms of disguisement - and not concealment, as claimed by the received view - that violate two important conversational responsibilities of the speaker (Clark and Carlson 1992).
