Lallu Lal

There, Lallu Lal translated and authored several literary works into modern vernacular Hindi.

[2] Lallu Lal's most notable translation is Prem Sagar (1804–1810), the earliest prose in Khari Boli dialect of Hindi.

[3] Lallu Lal's original work included The Grammar of Brij-bhasa (1811), in Urdu script.

The earliest Hindustani language literature made heavy use of Persian words, and resembled modern Urdu.

Linguist Jules Bloch describes the importance of Lallu Lal's work as follows:[7] Lallu Lal, under the inspiration of Dr. Gilchrist, changed all that by writing the famous Prem Sagar, whose prose portions are on the whole Urdu, from which Persian words have been throughout replaced by Indo-Aryan words… The new dialect gave a lingua franca to the Hindus.The book was inspired stylistically by the Caurāsī Vaiṣṇavan kī Vārtā, a 17th-18th century Braj Bhasha text written by Harirāy.
