hindustani

Etymology

Borrowed from Hindustani ہِنْدُوسْتانی (hindūstānī) / हिंदुस्तानी (hindustānī), which came from Classical Persian هِنْدُوسْتَانِی (hindūstānī), made up of هِنْدُو (hindū, "Hindu, Indian"), ـسْتَان (-stān, "land"), and the adjective suffix ـِی (-ī). It is equivalent to Hindustan + -i.
