This paper reconsiders the French argumentative and polyphonic connector puisque, which has been studied extensively in pragmatics and enunciative linguistics. Although puisque and parce que share a causal meaning, it is widely recognized that the former, in comparison with the latter, introduces a fact not as directly causing another fact, but rather as justifying an utterance about another fact. Puisque is therefore considered polyphonic, since it conveys a point of view that is not directly undertaken by the speaker, but towards which the speaker takes a position, either through affiliation (the speaker ultimately adopts the point of view) or disaffiliation (the speaker takes the point of view only into account, like in the typical sentence “since [puisque] you ask”). The originality of the present contribution lies in the adoption of a multimodal perspective on the polyphonic dimension of puisque, by looking at pointing gestures and shifts in gaze direction that cooccur with the connector. The aim is to study to which extent and for what argumentative objectives the polyphony of the French connector puisque can be achieved multimodally. The data analyzed are taken from a video-recorded corpus of public and TV debates that address social and political issues in Switzerland.
