A Comparative Grammar of the Dravidian or South Indian family of languages

Comparative Grammar of the Dravidian or South Indian Family of Languages by Robert Caldwell, published in 1856, is a seminal work in Dravidian linguistics. It systematically compares the major Dravidian languages, such as Tamil, Telugu, Kannada, and Malayalam, analyzing their phonological, morphological, and syntactic features. Caldwell's research laid the foundation for future studies of South Indian languages, offering insights into their common origin and structure. His work remains essential in understanding the linguistic history and relationships among Dravidian languages.
