Unaccusativity and L2 Passive Construction

Unaccusativity and L2 Passive Construction

  This study investigated whether and how semantic nature of intransitive verbs can be related to the L2 overpassivization errors. A total of 126 Korean high school students participated in a grammaticality judgment test on English sentences in which seven semantically different types of intransitive verbs were passivized. The results showed that there was an effect of semantic type on the students" judgment on overpassivization errors. Overall, it was shown that the students experienced the lowest degree of difficulty with the Controlled Process-Motional type verbs while experiencing the high degree of difficulty with the Change of State, Existence of State, Continuation of Pre-existing State, and Uncontrolled Process types. Two interlanguage patterns were also identified: the students at higher proficiency level and those at lower-proficiency level showed distinctive patterns on the task. It was argued that the simple dichotomy of unaccusative-unergative distinction does not suffice for the explanation of the complex phenomenon of L2 overpassivization.
