* Origins: Hindi's roots lie in Prakrit languages, which evolved from Sanskrit around the 5th century BC.
* Development: Over centuries, various Prakrit dialects merged and influenced each other, eventually leading to the development of Apabhramsha, a precursor to modern Hindi.
* Formalization: The modern standard Hindi language we know today took shape in the 19th century, heavily influenced by Persian and Urdu, and was standardized by the British during their colonial rule.
Therefore, Hindi doesn't have a specific "discovery date." It's a language that has been developing and changing for centuries, reflecting the complex history and influences of the Indian subcontinent.
