India is well-known to represent unity in diversity across all levels including linguistic. Linguistic diversity exists at multiple levels, and at the same time, the idea of India (South Asia) as a linguistic area is also well argued and accepted. This co-existence of linguistic unity and diversity has been an important topic of socio-political deliberation and of academic researchon the Indian languages. The Indian linguistic research from core linguistics and grammar to socio-and ethno-linguistics has been significantly contributingto the framing of the national language policies (and corrections thereof) and has provided effective inputs for empowerment and revitalization of various speech communities and their social and national integration and harmony. To a great extent, the Indian linguistic scenario is also the global reality and the equivalent case of the Philippines is not much different. In this talk. I propose to present a brief outline of the present Indian linguistic scenario with an aim to familiarize the young linguistic researchers and students (in the intended audience). The broader objective is to explore and outline some areas for potential academic collaborations and engagement where the research questions and insights are mutually feeding. I will conclude with a particular focus on an emerging, engaging and impactful area of research in linguistic landscaping (with examples of signages, commercial advertisements, etc. in the public spaces in the Indian city of Varanasi).
