Raja Rammohun Roy's 'Gaudiya Byakaran' (Grammar of the Gaudiya Language) is not just a textbook, but a historical cornerstone in the construction of the structure of the modern Bengali language. Published in 1833, this unique creation is the first complete Bengali grammar written by a Bengali, which helped establish Bengali as the common people's own language by freeing it from the then-prevailing influence of Sanskrit. Written in extremely clear and comprehensible prose, this book contains such a meticulous analysis of the evolution and application of language that it is equally attractive to everyone—from researchers to generally curious readers. To recognize the roots of modern Bengali literature and to perceive the infantile form of Bengali prose from two centuries ago, it is essential for every conscious Bengali to have this timeless classical book in their collection.
