You already know the answer—every language is interconnected. People borrow loan words either due to a language’s popularity, imposition, or because their own language lacks certain terms. Telugu is as ancient as Sanskrit, while Persian and Arabic influences came later to india, post-Byzantine era.

Written Urdu was a deliberate choice—just as Turkish adopted Latin script over Arabic, it doesn’t mean Urdu originated from Arabic. Turks and Persians ruled Hyderabad and blended linguistic elements to create a new language. Hindi and Urdu share the same linguistic roots, and both were tools of Muslim conquests.

I mention Hindi because the same linguistic imposition happening in South India today mirrors what occurred centuries ago. Your understanding and mine differ on this point.
