Historical Evolution
Hindustani arose in the Delhi region from Khari Boli vernaculars infused with Persian, Arabic, and Turkic elements during the Delhi Sultanate and Mughal periods. Hindi and Urdu later diverged sociolinguistically: Hindi Sanskritized its educated register under standardization in Devanagari, while Urdu Perso-Arabicized and adopted Nastaliq script. Spoken Hindustani remains largely mutually intelligible across the Hindi–Urdu spectrum.
Phonology
The core system includes ten vowels (oral and nasal) and a stop series with contrastive aspiration (e.g., क /k/ vs ख /kʰ/). Retroflex consonants are phonemic and socially salient. Stress is typically penultimate, and schwa deletion (हिन्दी → /hɪndiː/) is a hallmark of fluent Hindi speech.
Syntax
Hindustani is SOV with postpositions and ergative alignment in perfective past clauses (ने marking transitive agents). Verbs agree with subjects in gender and number; aspect is expressed periphrastically with auxiliaries. Honorific strategies include plural verb agreement for singular superiors and specialized pronoun forms.
