This book delves into how migration is depicted through multilingual discourses, blending corpus linguistics and critical discourse analysis. Emerging from a colloquium at Jaume I University in Castellón (Spain), it links translation studies, migration, and discourse analysis, revealing migration as more than physical movement. It is a cultural, ideological process rooted in language. Through four sections, it examines migration's complexities: theoretical frameworks, multilingual political discourse, grassroots narratives, and methodological advances like MD-CADS. Key themes include ideological framing of concepts like "diversity" and "security," the clash between global mobility and restrictive policies, and challenges such as climate-induced migration and digital misinformation. This work challenges dominant narratives, urging nuanced understanding of migration's global impact.
