We propose a semantic analysis of the particles afinal (European Portuguese) and alla fine (Italian) in terms of the notion of truth unpersistence, which combines both epistemic modality and constraints on discourse structure. We argue that the felicitous use of these modal particles requires that the truth of a proposition p* fail to persist through a temporal succession of epistemic states, where p* is incompatible with the proposition modified by afinal/alla fine, and that the interlocutors share knowledge of a previous (...) epistemic attitude toward p*. We analyze two main cases, that of plan-related propositions and that of propositions without plans. We also discuss the connections between truth unpersistence and evidentiality. (shrink)

This paper explores the diachronic development of the English adverb again. A compositional semantic analysis of its grammar at various stages is provided. It is argued that this analysis must consist of a staging of first a lexical and then a structural change, in order to adequately model the sequence of individual developmental steps observed in the historical corpus data, and that it provides an insight into pathways of semantic change in general.
