It is assumed that the content of an assertion is determined either by the semantically defined content or by the interaction of the latter with the context. Here I present a counterexample by means of the Wookiee problem. After considering several options I offer what appears to be its most satisfactory solution. This requires that we give up the assumption in favor of a view according to which it may be that semantic information does not at all determine the content of an assertion, not even partly so
