Linguistic diversity is the study of the variety of languages spoken by different populations around the world. This research area explores the different factors that contribute to language diversity, such as historical and cultural influences, geographical isolation, colonization, migration, and globalization. Linguistic diversity also examines the benefits and challenges of having multiple languages spoken within a society, including issues related to language preservation, language endangerment, language revitalization, and language policy. Researchers in this field often work to document and analyze different languages, study patterns of language usage and contact, and promote linguistic diversity as a valuable aspect of human culture.
