Urdu Lughat (in historical principle) is a lughat of Urdu Dictionary Board that has been compiled in the light of historical principles, which is relied upon and liked owing to its comprehensiveness, research and diversity. While compiling its lughat (on historical princples), this is prime obligation of Urdu Lughat Board to incorporate and follow such principles.The leading one is to follow the historical principles themselves i.e. reference and its periodic referenc while as well as quoting of most of the contents from already existing or past dictionaries. A period of more than fifty two years has been elapsed of the printing of initial four volumes of Urdu Lughat (on historical principle) during which hundred of thousands of words have been incorporated in Urdu language. It will be well justified if such new words be included with their reference in the upcoming editions to make the Lughat as solid and firm.
