In this paper I will try to explore how the voice as a grammatical category in Indo-European languages is expressed in Hungarian, Because Hungarian and Korean are grouped into the same typological class, in which the syntactic relations and the semantic meanings are realized morphologically, this study helps to examine the recent tendency of unacceptable derivations of passive -verbs in Korean and to find its solutions. In Hungarian, the expressions of passive meaning are realized either on morphological level. or on syntactic level. On morphological lovel. the passivity is expressed with the oppositions of transitive vs intransitive verb pairs, which are derived from same lexical roots, such as active-transitive verbs, middle verbs and passive verbs, If an active-transitive verb has no its intransitive pair, the passive expression is realized on syntactic level by the subjectless sentences with active-transitive verbs, It results from the hungarian word formational system of verbs, where each verb has its oppositional pari in transitivity and the re-derivation of passive verb from the middle verbs is not permitted.
