The paper provides a semantic analysis of intervention effects in wh-questions. The interpretation component of the grammar derives uninterpretability, hence ungrammaticality, of the intervention data. In the system of compositional interpretation that I suggest, wh-phrases play the same role as focused phrases, introducing alternatives into the computation. Unlike focus, wh-phrases make no ordinary semantic contribution. An intervention effect occurs whenever a focus-sensitive operator other than the question operator tries to evaluate a constituent containing a wh-phrase. It is argued that this (...) approach can capture the universal as well as the crosslinguistically variable aspects of intervention effects, in a way that is superior to previous approaches. Further consequences concern other focus-related constructions: multiple focus data, NPI licensing, and alternative questions. (shrink)

It is well known that indefinite phrases are more liberal in taking scope than other quantifying phrases. In general, the scope of indefinites is not limited by the finite clause in which they occur, although the scope of universal quantifiers is. Wh-phrases behave very much like indefinites: in languages with wh in situ, their scope need not be restricted by anything like clause boundedness.

In the framework of the minimalist program, the assumption that wh-in-situ move covertly to be assigned wide scope is infeasible. Rather, it is assumed that they must be interpretable in situ, and that syntactic conditions like ‘superiority’ are effects of economy, which restricts overt rather than covert movement of a wh-element. The remaining syntactic problem for this line of reasoning is the putative ECP effects of adverbial wh-adjuncts, which were the strongest evidence for covert movement. A serious semantic problem is (...) that the interpretative procedures which have been proposed for wh-in-situ – unselective binding or absorption – fail to capture correctly their interpretation. I will argue first that both problems are solved if the interpretation in situ employs choice functions, and it is the function variable, rather than an individual variable, which is long-distance bound by the question existential operator. Adverbial adjuncts, which cannot be interpreted via choice functions, cannot, therefore, be interpreted in situ. However, the concept of economy underlying the account of overt superiority effects requires both theoretical and empirical clarification (as it leaves some empirical problems unaddressed). I argue, following a proposal by Golan (1993), that in this case the economy considerations apply at the interface (‘interface economy’) and that they consider not only different derivations out of the same numeration, but also their semantic representation.

A recent popular analysis of English indefinites isthat they involve a choice function mechanism in their semantic interpretation. However,there are diversified views regarding how intermediate scope readings should be dealt withand which level(s) existential closure should apply to. This paper attempts to make acontribution to this debate by examining existential polarity wh-phrases in Chinese. I showthat unlike the behaviors of polarity indefinites in St''át''imcets reported by Matthewson(1999), intermediate scope readings are possible for polarity wh-phrases in Chinese but aresubject to some (...) locality conditions. I suggest that implicit arguments of choice functionsmight have a parametric value the choice of which affects availability of intermediate readings.The findings in this paper thus revive the possibility, rejected by Matthewson (1999), that thechoice function mechanism may vary from language to language or from indefinite NPs in onelanguage to indefinite NPs in another language or even from one type of indefiniteNP to another type of indefinite NP within the same language.
