This paper investigates the bodily signals of vagueness. After presenting the conceptual notion of vagueness by contrasting with uncertainty, approximation, confusion and ambiguity, the notion of “metadiscursive vagueness signal” is presented, a case of metadiscursive signals that convey “I am being vague”. Then a qualitative analysis of bodily signals of vagueness is presented, while singling out their physical features and outlining a typology of signals and a typology of reasons to be vague.
