Кратка характеристика на пасивните конструкции в българския книжовен език (съпоставени преди всичко с полския език)

The paper is a brief contrastive study of the characteristics of passive constructions in the Bulgarian literary language and in Polish. The basic reasons which determine the special position of Bulgarian among the other Slavic languages as regards the passive are given, namely the particular development of Bulgarian from a synthetic to an analytic structure which has led to the decomposition of the subject and object infinitives and to the wide spread of the so-called да-sentences in Bulgarian.
