Switch-reference has been analyzed as a reference tracking mechanism, whose main function is to avoid ambiguity of reference. One domain where this function has been argued to manifest itself is referential choice. Kibrik (Kibrik, Andrej. 2011. Reference in discourse. Oxford: Oxford University Press) notably proposed that switch-reference marking plays the role of a referential aid, which helps to prevent referential conflict, thereby enabling the production of reduced referential expressions such as pronouns and zeros. The present study probes this theory through an analysis of the role of switch-reference marking in multifactorial models of referential choice in Mbyá Guaraní. We show that while switch-reference increases the likelihood of mention reduction in Mbyá Guaraní, this effect is marginal relative to other predictors of referential choice. We argue that this result is compatible with the analysis of switch-reference as a referential aid, but also supports analyses that emphasize the multiplicity of its functions, beyond the disambiguation of reference.

This paper analyzes the contribution of the meh particle in biased questions in Colloquial Singapore English (CSE). Canonical CSE questions can be formed with inversion, or with declaratives with rising intonation (maintaining neutrality), while non-canonical questions typically require discourse particles. Meh occurs clause-finally (It’s raining meh?) and has been described to mark questions and express skepticism, encoding the opposite of what the speaker thinks to be true. Drawing from Romero and Han (2004), I propose that meh contributes the meta-conversational operator verum, which triggers the existence of an epistemic implicature.
