Re: Why is Urdu considered an Aryan language?
By ‘working on grammar’ here you mean “defining” the grammar of a language. This work does not change the way people speak a language.
What does script has to do with the origin of a language?
I don’t like to give up Persian script for Urdu but fact is that Persian/Arabic script is foreign to all local languages (Urdu, Punjabi, Sindhi, etc.) and had to be modified to fit the language. Same is the case with all Northern European languages who modified the foreign Roman script to fit their respective language.
