What Is Aurat
I think you are not taling and confusing the word with “satar” and “Hijab” when evloved. In its specific and literal meaing “aurat” refers to [Cover, hidden, intimate parts etc] upto this extent ‘aurat’ means the same. But if you are asking in islamic point of view, it would be different. Also, while transitioning from Arabic to Persian and Urdu, the word evolved to “which needs to be protected or covered” but still I assume that you are not talking about “satr” or “hijab” which epistemologically different.
