The focus of this book is how Slavic languages represent spatial relations, and how spatial cognition and perception influence the understanding and linguistic coding of nonspatial domains. Individual analyses concentrate on the semantics of selected prepositions and cases in Bosnian/Croatian/Serbian (B/C/S), providing a comparative perspective on other Slavic languages, primarily Russian and Polish. The opening analysis discusses the main theoretical notion – metaphorical extension – exemplifying the relation of spatial usages of linguistic items to non-spatial usages. This is followed by an analysis of the most basic spatial relations, “in-ness” and “on-ness.” The meaning network of prepositions equivalent to on and in helps explain the meaning of the cases they combine with: the accusative and locative. Another crucial spatial relation, proximity, is taken into account in the semantic analysis of the B/C/S prepositions kod and pri, their Slavic equivalents, and cases they combine with: the genitive and locative. The next chapter deals with the spatial meaning of the dative case, examining dative’s prepositional usages, the bare directional dative in B/C/S, and the semantic relation of the bare directional dative to other meaning domains of this case.
