Language diffusion refers to the process through which languages spread from their place of origin to other areas, influencing and transforming communication practices in diverse cultures. This phenomenon occurs through various mechanisms such as migration, trade, colonization, and cultural exchange, shaping how languages evolve and interact over time. Understanding language diffusion is essential for grasping the broader implications it has on regional identities and the diffusion of religions, which often intertwine with linguistic changes.
