A ‘multiple-proposition phenomenon’ is a putative counterexample to the widespread implicit assumption that a simple indicative sentence semantically expresses at most one proposition. Several philosophers and linguists have recently developed hypotheses concerning this notion. The guiding questions motivating this research are: Is there an interesting and homogenous semantic category of MP phenomena? If so, what is the import? Do MP theories have any relevance to important current questions in the study of language? I motivate an affirmative answer to, and then (...) argue that MP theorizing is quite relevant to debates at the semantics/ pragmatics interface. (shrink)

A pragmatic account of referential communication is developed which presents an alternative to traditional Gricean accounts by focusing on cooperativeness and efficiency, rather than informativity. The results of four language‐production experiments support the view that speakers can be cooperative when producing redundant adjectives, doing so more often when color modification could facilitate the listener's search for the referent in the visual display (Experiment 1a). By contrast, when the listener knew which shape was the target, speakers did not produce redundant color (...) adjectives (Experiment 1b). English speakers used redundant color adjectives more often than Spanish speakers, suggesting that speakers are sensitive to the differential efficiency of prenominal and postnominal modification (Experiment 2). Speakers were also cooperative when using redundant size adjectives (Experiment 3). Overall, these results show how discriminability affects a speaker's choice of referential expression above and beyond considerations of informativity, supporting the view that redundant speakers can be cooperative.
