The fluency of a language and its nuances are essential for the students in order to learn and know how to recognize to become good linguistic and intercultural mediators. This paper therefore presents a didactic activity in which, in the first place, and taking for granted the general linguistic competences of the French students (with level B2-C1 of Spanish as a Second Language in accordance with CEFR, 2001) with whom the activity has been carried out, the aim is to make them reflect on their previous attenuating pragmatic knowledge in order to improve their communicative skills that they need to develop in the profession of linguistic mediators. Based on this, it is intended that students learn to recognise not only when it is necessary to use attenuating elements as a linguistic strategy but also when they can and must do so as the situation requires.
