Umaraukosha (1807 AD) by Suvamsha Shukla of Biswan, district Sitapur, is based on the famous Sanskrit work Amarakosha (4th cent.), which was confined to define the gender of terms in Sanskrit. It goes to the superb intellectual dexterity and genius of Suvamsha, to improve upon the original source. Umaraukosha is an all round dictionary. It is a treasury of Sanskrit, middle Brajabhasha, and modern Khariboli terms: more than 11,000 of which are indexed at the end.
