The Role of the Lexicon in Lexical-Functional Grammar - Example on Croatian

The LFG model is based on an enriched lexicon, which contains associations between grammatical functions and their arguments, enabling decomposition on characteristic features and is suitable for formal description of languages with a rich morphological structure and a relatively free word order. Rejecting syntactic movement of constituents as the mechanism for realization of the surface syntactic structure, it is based on the idea of grammatical functions presented in the lexicon. In the paper the role of the lexicon is presented, as well as its close interaction with constituent and functional structures. In a formalization of Croatian sentence structure based on LFG, a new type of lexicon organization has been proposed, containing grammatical functions relating to argument structure, new features and constraints. Theoretical models are verified through educational version of the LFG model. Vloga leksikona pri formalnem modelu LFG – primer hrvaščine Model LFG temelji na obogatenem leksikonu, ki vsebuje povezave med slovničnimi vlogami in argumenti, kar omogoča razčlembo na značilke, ki se kažejo kot ustrezne za formalni opis jezikov z bogatim oblikoslovnim ustrojem in relativno prostim besednim redom. Model zavrača skladenjske pretvorbe konstituentov kot načina za uresničitev površinske skladenjske zgradbe in za osnovo vzame idejo o slovničnih funkcijah, zajetih v leksikonu. V članku je predstavljena vloga leksikona kot tudi tesnih povezav med gradniki in funkcijsko zgradbo. Pri postopku formalizacije hrvaških stavkov je bil predlagan nov tip organizacije leksikona, ki vsebuje slovnične vloge povezane z zgradbo argumentov, novimi značilkami in omejitvami. Teoretični modeli so preverjeni z izobraževalno verzijo
