Hindi grammar Study Guide

📖 Core Concepts Registers & Scripts – Hindi (Devanagari) vs. Urdu (Nastaʿlīq Perso‑Arabic). Vowel symmetry – 10 vowels: short /ə, ɪ, ʊ/; long /ɑː, iː, uː, eː, oː, ɛː, ɔː/. Gender, number, case – nouns: masculine/feminine; singular/plural; nominative, oblique, vocative. Split ergativity – perfective transitive verbs use ne (ergative) on the subject; agreement shifts to the object. Postpositions – require the noun in the oblique case; primary (e.g., kā, sā, se, ko). Verb aspects – perfective, habitual, progressive; marked by participles that agree with the noun. Copula honā – five moods; auxiliary for compound tenses. Word order – default S‑O‑V; flexible because case marks grammatical relations. 📌 Must Remember Short vs. long vowels: /ə, ɪ, ʊ/ (short) vs. /ɑː, iː, uː, eː, oː, ɛː, ɔː/ (long). Ergative rule: In perfective transitive clauses, subject + ne; verb agrees with the direct object. Primary postpositions (8) always take an oblique noun; kā and sā also agree in gender/number/case. Comparatives: adjective + instrumental se + oblique noun; zyādā optional, kam obligatory. Superlatives: sab + instrumental se + adjective. Plural formation: insert ‑y‑ after vowel‑ending stems; special rules for ‑ā (family) and ‑ū/‑ī stems. Future suffixes: ‑gā / ‑ge / ‑gī attached to the subjunctive stem. Passive: perfective participle + auxiliary jānā; agent marked by se. 🔄 Key Processes Forming the oblique case → add appropriate noun ending (depends on declension type). Creating a plural noun: If stem ends in vowel → insert ‑y‑ + plural suffix. ‑ā family nouns → no change in nominative plural. ‑ū / ‑ī stems → shorten to ‑u / ‑i before oblique & vocative plural, add y in vocative plural. Comparative construction: Adj (nom) + se + Noun (oblique) → optional zyādā before se for “more”. Superlative construction: sab + Adj (nom) + se → “the most …”. Perfective ergative clause: Subject + ne + Object (accusative ko if definite) → verb in 3sg masc default. If object indefinite → remains nominative, verb agrees with object gender/number. Passive formation: Perfective participle + jānā → “is/was …ed”; add agent with se. 🔍 Key Comparisons /ʋ/ allophones vs. English distinction: v w → Hindustani speakers treat them as the same phoneme. Se vs. Ko (postposition): se = instrumental/soft suggestion; ko = accusative/dative/direct command. Ergative vs. Non‑ergative verbs: Ergative verbs allow ne + object ko (perfective); Non‑ergative verbs keep subject nominative, normal agreement. Declinable vs. Indeclinable adjectives: Declinable: change with gender/number/case; Indeclinable: fixed form, may end in ‑ā or ‑ī. ⚠️ Common Misunderstandings Assuming /v/ and /w/ are separate phonemes – they are not; native speakers merge them. Using kā as a case marker – it is a genitive postposition, not a case suffix. Applying split ergativity to all aspects – it only appears in the perfective aspect. Treating ko as only accusative – it also marks dative/experiencer subjects with certain verbs. Adding ‑y‑ to every plural – only when the stem ends in a vowel; family ‑ā nouns are exempt. 🧠 Mental Models / Intuition “Ergative = Agent‑on‑ne” – picture the subject wearing a badge (ne) when the action is completed (perfective). Postposition = “oblique‑plus‑helper” – think of each postposition as a small verb that needs the noun in a special “ready” (oblique) form. Comparative = “instrument” – the instrumental se works like “with” in English (“more with X”). Passive = “go‑plus‑done” – jānā (“go”) + perfective participle = “be done”. 🚩 Exceptions & Edge Cases Ergative‑free transitive verbs (lānā, bhūlnā, milnā) never take ne; they agree with the subject. Family nouns ending in ‑ā (e.g., pāpā) do not change in the nominative plural. Irregular multipliers – the first three numerals change the root before adding ‑gunā. Compound postpositions with personal pronouns – drop the genitive oblique (e.g., mere andar, not mujh‑ke andar). 📍 When to Use Which Choose se vs. ko with bolnā: se → softer, suggestive (“speak with…”) ko → direct command (“speak to…”) Select ergative construction: only in perfective transitive clauses with a definite, animate object. Pick the correct postposition: kā for possession (genitive); ke pās for owned objects; ke pās mẽ for “nearby”. Use jānā as passive auxiliary when you need a true passive voice; otherwise rely on context‑driven intransitive usage. 👀 Patterns to Recognize Oblique‑required pattern: any primary postposition → noun will end in the oblique case marker. Ergative‑perfective pattern: Subject‑ne Object‑ko Verb → expect default 3sg masc verb form. Comparative‑optional‑zyādā pattern: if “more” is explicit, zyādā appears before se; if omitted, comparative still works. Superlative‑sab‑se pattern: always start with sab followed by adjective and se. 🗂️ Exam Traps Mistaking kā for a case suffix – an answer that treats it as nominative will be wrong. Applying split ergativity to habitual aspect – only perfective triggers ne. Choosing ko for all instrumental meanings – ko is not instrumental; it marks accusative/dative. Adding ‑y‑ to ‑ā family nouns in plural – these nouns stay unchanged; a distractor may suggest otherwise. Assuming all transitive verbs take ne – remember the three exceptions (lānā, bhūlnā, milnā). --- Study this guide repeatedly; the bullet format makes it easy to scan right before the exam.
