In recent years, migration across urban centers and national borders has radically reshaped West African societies and sparked a global debate on the legal and cultural processes of immigration. Along newly constructed international highways linking Senegal and Mali, young men and women travel between regional centers and their hometowns in the wake of a gold-mining boom that has brought new opportunities as well as risks.Previous scholarship on migration has often emphasized the physical movement of bodies and things. Instead of considering language primarily as a way to describe mobility as it happened, Nikolas Sweet positions language as an essential infrastructure through which individuals forge material connections and communication channels across space and borders. This reinterpretation of migration emphasizes that language is a form of social action in its own right—one that does not merely reflect experiences in the world but can bring things into being. Becoming a migrant in this setting not only reflects an individual's mobile history, but also depends upon that person's successful embodiment of the migrant role through everyday verbal performance.Through ethnographic research on social interaction, verbal creativity, and mobility in southeastern Senegal, reveals how migrants use language to build social networks and mitigate risk amid socioeconomic and environmental precarity.
