Re: Speaking hindi…good or bad?
Your bolded sentence has three negatives lump sump together. 
Basically you are saying Hindi can have word from Sanskrit. That is what I expect.
But I never said Hindi cannot borrow words from Sanskrit.
And if it does then it should be called Urdu. People have changed the name of Urdu to Hindi just beacuse of division of Indian sub-continent.
Why?
Urdu is the language which boasts of being a mixture of other languages, Sanskrit is not. Sanskrit is considered one of the many languages which later gave birth to other languages.
Urdu is different and is ever absorbing language. it is a “receiver language”. Sanskrit is not.
People call Urdu,… Hindi just to prove that they are different.
In regards to Amir Khusro. it is just another dialect of Urdu. And it can be considered “Classic” or Archaic Urdu as opposed to Modern Urdu.
Amir Khusro was and is still considered Urdu Poet. Some call that Hindavi language.
