The article derives from a corpus study of reduced parenthetical clauses (RPCs) in contemporary spoken French, Italian, and Spanish (cf. Schneider, forthcoming) and proposes a typology based on pragmatic criteria. The parentheticals are first subdivided into three major groups: phatic, reporting, and mitigating RPCs. Subsequently, drawing on the contributions of Hare (1970) and Caffi (1999, 2001), the group of mitigating RPCs is subdivided in four groups: a) clauses mitigating the phrastic; b) clauses indicating the tropic and mitigating the phrastic or the neustic; c) clauses directly mitigating the neustic; d) clauses indirectly mitigating the neustic. The taxonomy is shown to be corroborated by two independent phenomena: the positional mobility of RPCs and the occurrence of RPCs in interrogative sentences.
