U radu će se govoriti o odnosu jezika i prostora i elaboraciji takvog prostornog odnosa na razini zavisnosložene rečenice s mjesnom klauzom. U okviru semantičkih padeža za označavanje prostornih odnosa – lokativa, ablativa, adlativa i perlativa – izdvajaju se određeni podznačenjski tipovi koji se na razini složene rečenice s mjesnom klauzom kodiraju na različite načine. Za razliku od prijedložno-padežnih konstrukcija, u kojima su prostorni odnosi najprije iskazani padežnim značenjima i prijedlozima, na razini složene rečenice ti se prostorni odnosi označavaju uglavnom veznim sredstvima, a potom i antecedentima i postcedentima na koje vezno sredstvo upućuje. Mjesne klauze u složenu rečenicu uvode se odnosnim prilozima, koji svojim leksičkosemantičkim svojstvima iskazuju različite tipove i podtipove prostornih odnosa. Zato mjesna jeste prototipna kad je riječ o prostornim odnosima na razini složene rečenice, ali je i specifična na formalno-gramatičkom planu u odnosu na ostale tipove zavisnih klauza. S tim u vezi, usporedit će se i s atributnom klauzom uvedenom odnosnim prilozima.; The paper will discuss the relationship between a language and space and the elaboration of such spatial relationship at the level of a complex sentence with a spatial clause. Within the semantic cases of the spatial relationships – locative, ablative, adlative and perlative – there are certain submeanings that are encoded at the level of a complex sentence with a spatial clause in different ways. Unlike case-marked prepositonal constructions, in which spatial relations are expressed by case meaning and prepositions, these spatial relationships at the level of a complex sentence are generally indicated by conjuctions, and then by antecedents and postcedents to which the conjunctions refer. The spatial clauses in the complex sentence are introduced by relative adverbs, which express different types and subtypes of spatial relations with their lexical and semantic properties. When we talk about spatial relations at the level of a complex sentence, the spatial clause is a prototype and specific in the formally grammatical plan as compared to the other types of dependent clauses. We will also compare the spatial clauses with relative clauses introduced by relative adverbs.
