Hindustani (/ /; ; हिन्दुस्तानी, ہندوستانی), also known as "Hindi-Urdu," is a term used by linguists to describe several closely related idioms in the northern, central and northwestern part of the
Indian subcontinent and the vernacular blend between its two
standardized registers in the form of the official languages of
Hindi and
Urdu, as well as several
nonstandard dialects. These two standardized languages of Hindustani are nearly identical in grammar and share a basic common vocabulary. In fact, before the
Partition of British India, the terms Hindustani and Urdu were synonymous.
