The Linguistic Association of Korea Journal, 21(2), 89-113. The masked priming experiment conducted in present study shows that two types of V-V compounds in Korean have different lexical representations. Syntatic V-V compounds, whose second constituent is considered to be a light verb, are stored and accessed decompositionally. In contrast, lexical compounds, whose two constituent verbs are both fully lexical, are stored as a whole unit. Additionally, the reaction times for syntactic V-V compounds were faster than lexical V-V compounds regardless of the presence of primes. The findings from this study suggest that verbal compounds have a different status from nominal conpounds (e,g. Ko et al. 2011) in the mental lexicon and ate at odds with the results of Marslen-Wilson at al.(2)08), who found an early effect of morphological decomposition irrespective of semantic factors.
