Словообразувателно-семантична характеристика на транслокативните префиксални формации пре- и про- в български и сърбохърватски език

The article considers the translocative formations with the prefixes pre- and pro- in Bulgarian and Serbo-Croatian. A new classification of the derivatives considered is suggested, based on formal and semantic criteria, categories and sub-categories within the transgressive aktionsart and preceded by word-formation and semantic analysis combining elements of the theory of meaning as a hierarchic and predicate-argument structure. Contrastive observations on the kinds of motivating bases and on the etymological and functional proximity of pre- and pro- in both languages are made.
