TY - JOUR T1 - Преход на пълнозначни думи към предлози в съвременния български и чешки език JF - Съпоставително езикознание / Сопоставительное языкознание / Contrastive linguistics Y1 - 1989 A1 - Контева, Магдена AB - The paper discusses the origin of secondary prepositions derived from open-class words in Czech and Bulgarian. After clarifying the historical prerequisites and the lexico-syntactic characteristics of the separate parts of speech, the logico-semantic loci and the semantico-functional conditions for the transition of adverbs, nouns, verbs, pronouns and numerals to prepositions are determined. Changes occurring in open-class words on the syntactic and the lexical level are discussed. A classification of secondary prepositions according to their origin is proposed in view of the role of the initial words in the meaning of the preposition. VL - 14 ER -
