Here's why:
* Urdu is a language that originated in the Indian subcontinent, with significant influences from Persian, Arabic, and Hindi.
* Hindi and Urdu are closely related languages, sharing a common ancestor and a large amount of vocabulary.
* Urdu is often considered a "sister language" to Hindi, with differences primarily in the script and certain vocabulary choices.
So, while the word "Urdu" is used in both Hindi and Urdu, it refers to the same language. It's like saying "English" in English—it's the name of the language itself.
