How does language diffuse?

Language diffusion occurs through a variety of processes, including migration, colonization, trade, and cultural exchange. As people move from one region to another, they bring their language with them and often adapt it to fit into the new environment. Additionally, colonization and trade can spread languages to new areas as different cultures come into contact with each other. Cultural exchange, such as through media, technology, and social interactions, can also contribute to the diffusion of language as people are exposed to and adopt words and phrases from other languages.

In some cases, languages may also spread through the influence of a dominant language, such as English in the modern world. This can happen through political and economic power, as well as through the popularity of English-language media and entertainment.

Overall, language diffusion is a complex and dynamic process influenced by factors such as historical events, social interactions, and technological advancements.
