Contexts: everything you always wanted to know about context (but were afraid to ask)

We give a short recap of how the notion of context has been developed in the philosophy of language since its introduction by Frege. We introduce various aspects of the concept of context: context of utterance, context at the semantics-pragmatics boundary, and social and cognitive context. We thereby offer to readers not accustomed to the distinctions used in the philosophy of language a framework to better understand the papers enclosed in this issue (and of which we provide summaries at the end of this introduction).
