This paper investigates Negative Concord, arguing that it results from a systematic lexical ambiguity: the items that participate in Negative Concord ("n-words" in Laka's 1990 terminology) are ambiguous between negative polarity items and their genuinely negative counterparts. I try to show that on empirical grounds the proposed account compares favorably with other analyses that shy away from ambiguity. I furthermore suggest that the ambiguity is not implausible conceptually because it can be viewed as reflecting an intermediate stage of the Jespersen (...) Cycle. Negative Concord can be observed in many languages. The data discussed here are taken from Romance, primarily Spanish. (shrink)

Bare conditionals, I argue, exhibit Conditional Duality in that when they appear in downward entailing environments they differ from bare conditionals elsewhere in having existential rather than universal force. Two recalcitrant phenomena are shown to find a new explanation under this thesis: bare conditionals under only, and bare conditionals in the scope of negative nominal quantifiers, or what has come to be known as Higginbotham’s puzzle. I also consider how bare conditionals behave when embedded under negation, arguing that such conditionals (...) often involve denial negation. One important conclusion that emerges from the discussion is that an account of bare conditionals that validates Conditional Excluded Middle is not warranted. By limiting the scope of the strict analysis Conditional Duality is also a way of maintaining such an account. (shrink)
