The present study examines Spanish mood selection in a written preference task among intermediate and advanced-level second language (L2) learners of Spanish according to specific morphological and semantic linguistic features. Two intact university classes of English-speaking L2 learners of Spanish participated in the study: one advanced (N=20) and one intermediate (N=17) class. The written preference task includes subjunctive items coded for the presence or absence of four linguistic features: irregular subjunctive verbs, expressions of desire, expressions of futurity, and expressions of emotion. Results show advanced-level learners select the subjunctive significantly more than the intermediate-level participants. The linguistic features that significantly predict subjunctive selection also differ between the two groups. Whereas only irregular subjunctive verbs predict subjunctive selection for the intermediate-level learners, irregular verbs and expressions of desire work together to predict the advanced-level learners' subjunctive selection. Thus these results suggest that for L2 learners, morphological features of subjunctive verbs predict subjunctive selection before other semantic features such as desire, futurity, and emotion.
