This work aims to identify the main pragmatic interferences and highlight their relevance in its teaching in Spanish as a foreign language to Korean students. For this purpose, we have analyzed the theoretical aspects of pragmatics, making a brief theoretical review of the experts, including the linguists Gabriela Reyes and Mª Victoria Escandell, and taking as a reference the Curriculum Plan of the Cervantes Institute (PCIC). On the other hand, we have look at some forms completed by Korean students of Spanish language, as well as a survey to DELE teachers and examiners in the Republic of Korea, researching, for this reason, several works focused on the South Korean context.
