Синтактичен каузатив в българския, руския и белоруския език

The paper is devoted to one of the varieties of syntactic derivation in the dynamic syntax of the Slavic languages; causative relations connecting sentences of the type of: The train stopped – The engine/driver stopped the train, illustrated with examples in Bulgarian, Russian and Byelorussian. Four basic ways of expressing causative relations are considered: analytic, lexical, morphological and syntactic. Special attention is paid to the last of the above mentioned ways: the expression of causative derivation by means of the presence/ absence of a direct object. Colloquial speech is a specific area where the syntactic causative is used. The widely predominant phenomena of occasional dereflexivization and occasional transitivation testify to the productivity of this method of expressing causative relations as well as to the regularity of these relations in the consciousness of the Slav native speakers.
