Language contact is a field of study within linguistics that focuses on the interaction and influence of multiple languages on each other when they come into contact. This can occur through various means, such as trade, migration, colonization, and cultural exchange. Language contact can lead to language borrowing, code-switching, pidgin and creole formation, and various other linguistic phenomena. Researchers in this area seek to understand the impact of language contact on the development and evolution of languages, as well as the social and cultural factors that influence these processes.
