This special issue explores metaphor across languages, cultures, and discourses, bringing together papers that reflect the diversity and scope of this research area. The aim is to foster discussion and exchange ideas concerning the role of metaphor in conceptualization, persuasion, and the construction of meaning. In this introductory article, we focus on the two main themes: (1) the universality of metaphor versus cultural variations in its usage; (2) the communicative function of metaphor in discourse. Within these main themes, we discuss case studies that highlight specific domains, including universal and cross-cultural variation in metaphor usage, discursive and communicative aspects of metaphor, and multimodal metaphor. In this article, we provide a summary of the contributions of our authors that represent up-to-date research on issues involving metaphor from a wide scope of perspectives and manage to open up a methodological discussion within metaphor studies. Finally, we summarize the main results and suggest a brief avenue for further research.
