Various authors have attempted to understand knowledge-wh or knowledge ascriptions that include an interrogative complement. I present and explain some of the analyses offered so far and argue that each view faces some problems. I then present and explain a new analysis of knowledge-wh that avoids these problems and that offers several other advantages. Finally I raise some problems for invariantism about knowledge-wh and I argue that contextualism about knowledge-wh fits nicely with a very natural understanding of the nature of questions.
