Hindustani (/ˌhɪndʊˈstɑːni/; Devanagari: हिन्दुस्तानी, Hindustānī; Perso-Arabic: ہندوستانی, Hindūstānī, lit. 'of Hindustan') is the lingua franca of Northern and Central India and Pakistan.

Despite these standard registers, colloquial speech in Hindustani often exists on a spectrum between these standards.
