This chapter presents an account of notional belief attributions, that is, belief attributions where the belief content is fully specified. The proposal combines a Hintikka style possible-worlds semantics for the belief operator and a structured meanings approach for giving a structured mode of presentation of the belief content. The semantics is general compositional.  The general relation between compositionality and hyperintensional contexts is discussed. It is argued that we need to combine structured and unstructured meanings.
