How morphological decomposition manifests itself in the duration of the inter-morpheme period of silence in Russian prefixed verbs

Summary This study tests the morphological gradience theory on Russian prefixed verbs. With the help of a specially designed experiment, I offer evidence that verbs with prefixes that have prepositional counterparts and verbs with prefixes that exist only as bound morphemes reveal significant differences in terms of their morphological decomposition. In the pronunciation of native speakers, there tends to be a significantly longer silent period between prepositional prefixes and bases than between unprepositional prefixes and bases due to the compositional nature of the former and the non-compositional nature of the latter. Drawing on these findings, I contend that Russian prefixed verbs can be analysed as constructional schemas and that the degree of their morphological decomposition depends upon the different levels of activation of their sequential and lexical links.
