The book addresses some raging questions in linguistics today

What kind of variation do typologically related languages display? Do we expect to find the same variation in genealogically unrelated languages spoken in the same area? What makes dialects different? The current book answers these questions using data from languages spoken in the Indian subcontinent—an area known for its linguistic richness and diversity.

Each chapter in the book presents a wealth of data collected through extensive fieldwork or controlled experimental setups. The chapters examine macro-variation in relative clauses, word order and negation found among Austro-Asiatic, Dravidian, Indo-Aryan and Tibeto-Burman languages. It also investigates meso-level variation among related Eastern Indo-Aryan languages and intra-language and dialectal changes.

It encourages scholars to probe deep into the mechanisms that underlie the immense intra- and inter-language variation in the area. It serves as a resource book for postgraduate and research scholars of linguistic typology, theoretical syntax, sociolinguistics, historical linguistics and for scholars interested in South Asian languages.
