The CETEHIPL focuses on developing pedagogical applications of the NooJ linguistic platform. Using the Argentinian Spanish Module, we have developed various linguistic resources to help learners of Spanish, whether native speakers or not, improve their proficiency in reading and producing texts. In this paper, we study the opposition between two types of syntactic constructions in mainly northwestern Argentinian Spanish: concessive and conditional clauses. Our corpus comprises the lyrics of Atahualpa Yupanqui’s folk songs. In the first descriptive stage, we located the connectors introducing these subordinate clauses in the corpus. In a second productive stage, we used NooJ to recognize and generate the corresponding syntactic structures. We have adapted our dictionaries to process the expressions of Gaucho Spanish, and we have constructed new syntactic grammars that recognize conditional and concessive clauses, seeking to bring together the variety in both prototypical formats and emphasizing the notion of nucleus phrases.
