Bihari Grammar is a very valueable and rare grammar which was compiled by a great eminent linguist and philologist under the orders of the Government of Bengal. The grammar is in constant and urgent demand. No such document is available presently on the subject. Bihari Language is being spoken in the province of Bihar, in the eastern portion of the North western provinces and the northern portion of the central provinces. It is a compendium grammar of the dialect of each district compiled by the author for official use in the state for government officers. No grammar of any of the dialect of Bihar has even been published except the Bhojpuri grammar of Mr. Beames. No other grammar meets the demand of Magadhi and Bhojpuri speaking parts of Bihar. This Grammar will no doubt meet demand of all. The grammar is a rare compilation and will be of greau set for all including students and teachers of Bihari language.
