За връзката между семантика на словообразувателната представка и валентност на изходните лексеми в немския и българския език

The article discusses the problem of the influence of the verbal prefix on the meaning, valency and Aktionsart of the original verbs. This interrelationship is revealed on the basis of auf-prefixed verbs in German and their equivalents with из- in Bulgarian which signal the achievement of a result as a consequence of the accomplishment of a particular action of the verb. A three-way model of analysis is used including the logical, semantic and syntactic valency of the verbs under investigation.
