Sitaram Kachru

Sitaram Kachru was an influential Indian-American linguist best known for his work on English language spread and usage worldwide. He co-developed the "Three Circles of English" model, which describes how English functions differently in countries where it is native, learned as a second language, or has become a global lingua franca. His research highlighted the cultural and social impacts of English's global expansion, emphasizing the importance of understanding diverse English varieties. Kachru's work has deepened our understanding of language dynamics in a globalized world, shaping policies and discussions around English language education and intercultural communication.
