In this article we propose a teaching unit aimed at including the teaching of phraseology in the ELE classroom. The proposal revolves around the central theme of phraseological units, which will be addressed from three perspectives (pragmatic, formal and semantic) and enhanced by a reflection on the relationship between phraseology and superstitious beliefs. It is designed to last for two sessions of 50 minutes and is aimed at students of Spanish as a foreign language with level C1 according to the CEFR. This unit has two objectives, which are to activate the students’ use of phraseological units and to reflect on their meaning figuratively. While it is intended to develop all the skills, the skills of oral expression and oral interaction are most predominant. With regard to language skills, lexical, semantic and orthoepic competence is emphasized.
