This investigation's goal was to add to the small body of research on pragmalinguistic acquisition of L2 Spanish. Specifically, it centered on the production of complaints in Spanish. Data was collected via a written Discourse Completion Task (DCT) of a complaint-provoking situation presented in a website voiceboard to two non-native speaker (NNS) students groups of different proficiency levels and to a native speaker (NS) control group. The lower proficiency group was comprised of 11 NNS enrolled in a 200 level beginning/intermediate Spanish grammar class and the advanced proficiency group of 11 NNS enrolled in a 400 level advanced Spanish conversation and composition class. Neither group contained any participants who had studied abroad or lived in a Spanish-speaking country for more than 3 months. The control group consisted of 10 NSs of Spanish who were all natives or current residents of Northern Mexico. Data from the DCT was categorized into strategies which were organized into Head Acts and Supporting Moves, Deference and Solidarity Politeness systems, according to the frameworks of Blum-Kulka, et al. (1989) and Scollon and Scollon (1983), respectively. The results of the analysis revealed that all three groups of participants have overarching similarities in the use of multiple Head Acts, some used several times throughout a response, to realize a complaint and used some Supporting Moves to mitigate these Head Acts. The lower proficiency group diverged from the advanced proficiency group and NS control group in that lower proficiency students not only used a fewer total strategies and strategy types, but also preferred Head Acts and Supporting Moves that expressed discomfort or dislike over strategies that expressed criticism, or requested a solution from the listener, these being the primary strategies preferred by the advanced proficiency and control group participants. It was also found that the percentage of Supporting Moves decreased with the raise in proficiency level, also. After a discussion of the results, pedagogical implications are given based on these results to help students notice and acquire pragmalinguistcally appropriate responses to complaint-provoking situations.
