Liangshan Nuosu (Tibeto-Burman: P.R. China) exhibits two cross-linguistically rare attitude particles which ascribe wishes and fears to an impersonal socialised agent serving as a speaker-hedge. Linguistic properties of these particles not covered by (Potts, 2007a) and (Potts, 2007b) features of expressive content are elaborated upon. It is proposed to analyse the Nuosu attitude operators as illocutionary force indicating devices (IFIDs, see Searle and Vanderveken, 1985) and the utterances which host them as speech acts of the expressive type. Success conditions for (...) these speech acts are developed in a fuzzy logic system providing an accurate account of both successful and unsuccessful attitude ascriptions. The fuzzy logic system builds on the distinction between lower-level and higher-level formulae (following Thijsse (1996) and Schwartz (2003)). For lower-level formulae it incorporates a fuzzy epistemic and a fuzzy buletic mode of evaluation. Higher-level formulae are evaluated in a bivalent evaluation mode {successful, unsuccessful}.

Of late, evidentiality has received great attention in formal semantics. In this paper I develop ‘evidentiality-informed’ truth conditions for modal operators such as must and may . With language data drawn from Luoping Nase (a Tibeto-Burman language spoken in the P.R. of China and belonging to the Yi Nationality), I illustrate that epistemic modals clash with clauses articulating first-hand information. I then demonstrate that existing models such as Kratzer’s graded possible-worlds semantics fail to provide accurate truth conditions for modals tagging (...) clauses with first-hand information. As a remedy I propose a fuzzy version of possible-worlds semantics with various grades of belief and knowledge. In addition to preserving the expressive power of graded possible-worlds semantics, the fuzzy model will be shown to supply appropriate truth conditions for epistemic modals appended to evidential clauses (i.e. clauses expressing first-hand information).
