Hi everyone, I am learning Hindi now. I know that Hindi together with Urdu belong to the Indo-Iranian branch to which Persian is also attached. Thus, I am wondering whether there exists a great similarity between Hindi and Persian in grammar structure and vocabulary. By vocabulary, I mean words common to the both languages AND which can be traced back to Proto Indo-Iranian, BUT not loanwords (I know in Hindi there are a lot of words borrowed from Persian). As to Urdu, can we say Urdu is to Persian what English is to French? As Udu is heavily influenced by Persian for its vocabulary, which makes Urdu different from Hindi whose vocabulary is more based on Sanskrit.
