SUMMARY
This article sets out to provide a semantic and pragmatic account of the modal particle ma ?, endeavouring to put into light new aspects in its function which, at present, remain widely unexplored in the literature. It presents an analysis of the particle ma by interrogating a written and a spoken corpus, showing how the semantic and the pragmatic levels are tightly interweaved in the functioning of ma: the results supported my hypothesis that the particle is plausibly a marker of interpersonal evidentiality (IE), a category set up by Tantucci (2013), used to signal a socially acknowledged piece of information, playing a fundamental role in the expression of politeness by safeguarding the interlocutors’ face; consequently, ma is always used with information that has an active or accessible status in the interlocutors’ mind and that is always pragmatically salient, independently of its position (at the end or inside the sentence), marking a Topic or a Focus. The particle performs pragmatic functions close to the ones of discourse markers since it increases the relevance of the marked information to the context, therefore also playing a contributing role in the coherence of discourse.
