This volume provides a comprehensive survey of mood in the languages of Europe. It gives readers access to a collection of data on mood. Each article presents the mood system of a specific European language in a way that readers not familiar with this language are able to understand and to interpret the data. The articles contain information on the morphology and semantics of the mood system, the possible combinations of tense and mood morphology, and the possible uses of the non-indica­tive mood(s). The papers address the explanation of mood from an empirical and descriptive perspective.
