Building on previous works which argued that scalar implicatures can be computed in embedded positions, this paper proposes a constraint on exhaustification which restricts the conditions under which an exhaustivity operator can be licensed. We show that this economy condition allows us to derive a number of generalizations, such as, in particular, the ‘Implicature Focus Generalization’: scalar implicatures can be embedded under a downward-entailing operator only if the scalar term bears pitch accent. Our economy condition also derives specific predictions regarding (...) the licensing of so-called Hurford disjunctions. (shrink)

We discuss focus sensitivity in English, the phenomenon whereby interpretation of some expressions is affected by placement of intonational focus. We concentrate in particular on the interpretation of always and only, both of which are interpreted as universal quantifiers, and both of which are focus sensitive. Using both naturally occurring and constructed data we explore the interaction of these operators with negative polarity items, with presupposition, with prosodically reduced elements, and with syntactic extraction. On the basis of this data we (...) show that while only lexically encodes a dependency on the placement of focus, always does not. Rather, the focus sensitivity of always results from its dependency on context, and from the fact that focus also reflects what is given in the context. We account for this split using an analysis couched in event semantics. (shrink)
