The status of the unaccusative/unergative split in the Croatian-English interlanguage*

By employing the two types of errors well-documented in the literature on the L2 acquisition of English unaccusatives, namely passive morphology and postverbal subjects, this study investigates the status of the unaccusative/unergative split in the Croatian-English interlanguage and the issue of UG involvement in L2 acquisition. Despite being unable to provide a full and unified account of the common response pattern obtained from native and non-native speakers, the study demonstrates that unaccusatives and unergatives are represented as distinct verb classes in the Croatian-English interlanguage and argues that such representations could not have been acquired without access to UG.
