Metasemantics, context, and felicitous underspecification

King’s Felicitous Underspecification (FU) is a rich, thought-provoking book, which draws on a wide range of novel and largely unappreciated linguistic examples to argue that we should take the idea of a felicitously underspecified use of context-sensitive language very seriously. If felicitous underspecification is as prevalent as King argues, understanding the mechanisms involved in its interpretation is crucial for our overall understanding of linguistic communication. FU further offers a sophisticated account of these mechanisms. In this piece, I critically examine some of the main themes in FU. In doing so, I raise some worries for the interpretive mechanisms King posits. Specifically, I pose some challenges for his intentionalist GCA meta-semantics, and raise worries about the central interpretive role he assigns to his proposed contextual update rule, FUU.
