Употреба на предлога на в определително значе115 ние в българския език и някои негови синтактични еквиваленти в полския и руския език

The paper discusses some nominal phrases which contain the preposition на and express qualifying relations. There has been no detailed study on this problem so far. The Bulgarian nominal phrases are contrasted with their syntactic equivalents in Polish and Russian and the distribution of the preposition is examined in terms of its relations with the lexical environment. The use of the prepositions s and v in the same meaning is discussed in terms of syntactic synonymy and combinatorial syntactic variants.
