“…Arguments for the adoption of conceptual metaphors include claims that this technique can help the learners enhance their understanding and retention of the target language, explore the link between language and culture and boost their confidence in learning L2 vocabulary in a more insightful way instead of relying on rote memorization Doiz & Elizari, 2013). Several empirical studies have proved that metaphor awareness can help enhance the comprehension, retention, and even production of idiomatic expressions (Khoshniyat & Dowlatabadi, 2014;Kartal & Uner, 2017;Pérez, 2018;Chen, 2019;Pham, 2019;Shan, 2020). In addition, a variety of CM-related activities have been designed and step-by-step guidelines on how to apply conceptual metaphors to teaching idioms have also been proposed to ensure that L2 learners can play an active role in their idiom acquisition with conceptual metaphors as an organizer and motivator of English idiomatic expressions (Pham, 2017;Pham, 2019;Upadhaya & Sudharshana, 2021).…”
