Употребата на словоформата един за изразяване на неопределеност в българския език, съпоставена с употребата на неопределителния член ein в немския език

The aim of the present, paper is to establish the correspondences and differences in the use of един and еin when expressing the idea of indefiniteness in Bulgarian and German. The generalizing and individualizing functions of еin and their expression possibilities in Bulgarian are considered. The theoretical solution of this problem has important practical implications for the further improvement of German language teaching at the Institute of Foreign Students.
