The Finnish language is perhaps best known for its rich case system. Depending on the definition of a case, Finnish has at least fourteen, possibly fifteen or even more cases. This volume is the first comprehensive English-language account of the Finnish case system, focusing primarily on its semantic functions. This collection of articles presents an up-to-date overview of the Finnish case system, analyses central subsystems within it, and offers data-based analyses of the functions of individual cases. The authors approach Finnish cases from different perspectives within the framework of Cognitive Linguistics. The volume also addresses more general topics, such as the notion of case, questions of polysemy, the traditional division of cases into grammatical and semantic, the relationship between inflection and derivation as well as the role of inflection in the structuring of the categories of adpositions and adverbs. The book will be of interest to linguists and students as well as to those readers who are not familiar with cognitive linguistics. The analyses presented here will be relevant to anyone investigating the essence of case and the emergence of linguistic meaning.
