This study aims to examine the Lexical Aspect Hypothesis (LAH) analyzing oral production made by Korean learners of Spanish. According to LAH, learners at the beginners`` level strongly prefer to use prototypical combination between lexical aspect and morphological aspect: telic verbs in perfective aspect and atelic verbs in imperfective aspect. However, as the proficiency grows, the hypothesis expects that such tendency would fade and the use of grammatical aspect would expand to non-prototypical combination. In this study, I applied one of the questionnaires used in Spanish Language Learner Oral Corpus 2 (SPLLOC 2), `` Las hermanas``, and a total of thirty Korean students (Beginner: 10, Intermediate: 10, Advanced: 10) participated in the recording. They were asked to complete a story describing the pictures of two sisters who went trip to Spain using twenty five verbs given in the questionnaire. The result did not support claims made by LAH that non-prototypical combination between the lexical aspect and morphological aspect prevailed even from the beginners group. Interestingly, instead of lexical aspect, discourse structure was confirmed to be exerting much stronger influence in the selection of morphological aspect.
