Abstract : In recent work, Jeffrey King has called our attention to the problem of "felicitous underspecification" : felicitous uses of context-sensitive language in the absence of determinate intentions about the needed contextual supplementation. An example would be talk of a "local shop" in the absence of a determinate intention about whether we mean local-to-the-city or local-to-the-county. After discussing the problems raised by this phenomenon, I consider King’s own solution and argue that it is inadequate. I then describe the solution I think is needed, which makes use of the ideas from Allan Gibbard’s plan expressivism. According to this approach, ordinary descriptive claims like "I went to a local shop" must be understood as expressive of practical plans for the use of words, as well as ordinary beliefs. Indeterminacy amounts to practical indecision.
