David G. Poplack

David G. Poplack is a linguist renowned for studying how bilinguals switch between languages in conversation, a phenomenon called code-switching. His research explores how people smoothly alternate languages to express themselves, reflect their identity, or navigate social contexts. Poplack’s work combines linguistics, sociology, and anthropology to understand the patterns, rules, and cultural significance of bilingual language use. His insights have advanced understanding of language contact, variation, and the social dynamics of multilingual communities.
