Hindustani is an Indo-Aryan language spoken in Deccan, Northern India and Pakistan, and used as a lingua franca in both countries. Hindustani is a pluricentric language with two standard registers, known as Hindi and Urdu. Thus, it is also called Hindi–Urdu. Colloquial registers of the language fall on a spectrum between these standards. In modern times, a third variety of Hindustani with significant English influences has also appeared which is sometimes called Hinglish or Urdish.

Hindi cinema, popularly known as Bollywood and formerly as Bombay cinema, refers to the film industry based in Mumbai, engaged in production of motion pictures in Hindi language. The popular term Bollywood is a portmanteau of "Bombay" and "Hollywood". The industry is a part of the larger Indian cinema, which also includes South Indian cinema and other smaller film industries.
