Summary: Muhammad Quli Qutb Sah was the first authentic poet of Urdu, using a Western Hindi speech with Panjabi affinities, not identical to Hindustani. Resources cite his existence and contribution to poetry until his death in 1611 A.C, being identified in historical texts like Braj-ratn Das. Further research and references by scholars like Cunningham and Fleet unveil the historical links and linguistic differences between modern Urdu and its earliest form. The complexities in morphological syntax, pronunciation, and dialectal variants in languages like East Bengali, Assamese, and Oriya are evident through script and inscriptions, indicating the evolution of language over different periods. Research also reveals various idiosyncrasies, phonetic challenges, and phonological transitions in literary texts, proverbs, and dialects like Bengali, Prakrit, and even Tibeto-Burman languages. The historical context and language progression provide insight into the linguistic diversity and changes in Urdu literature.
