It's important to note that:
* Hindustani itself is a linguistic continuum with variations in pronunciation, vocabulary, and grammar across its geographic spread.
* While Hindustani is spoken in both India and Pakistan, the official languages of these countries are Hindi in India and Urdu in Pakistan. These languages are very closely related to Hindustani and share a common ancestor.
Essentially, the terms "Hindustani," "Hindi," and "Urdu" are often used interchangeably, but they technically refer to closely related languages with slight distinctions.
