What is the relationship between migration and diffusion of language?

Migration and diffusion of language are closely interconnected processes. When people migrate, they often bring their native languages with them, which can then mix with the languages of the host communities, leading to language change, borrowing, or the emergence of new dialects. This diffusion can also occur through cultural exchange, trade, and social interactions, resulting in the spread of vocabulary, grammar, and linguistic features across regions. Ultimately, migration serves as a catalyst for linguistic diversity and evolution.
