By contrast it becomes clear that a modal construction congruent with the German construction sein + zu + Infinitiv exists in Bulgarian. The two constructions are parallel in syntactic and semantic terms, as well as in their historical development. There are some differences mainly on the stylistic level. The use of the Bulgarian construction is limited within the colloquial speech register, whereas the German construction occurs in all functional styles.1 aДимова, Ана  uhttp://scripta-bulgarica.eu/bg/biblio/dimova1983
