English Grammar

🟢 Lite — Quick Review (1h–1d)

Rapid summary of English Grammar for NDA GAT paper.

English Grammar in the NDA GAT paper tests your command over the mechanics of the language. The paper carries 20–25 questions from this section alone. Focus on five high-yield areas: tenses, voice, speech, subject-verb agreement, and articles. These topics alone account for roughly 60% of grammar questions in past papers (NDA 2023, NDA 2024).

Key Facts to Memorise:

• Present Perfect connects past to present: have/has + past participle (e.g., “She has left” — she left, and the effect continues)
• Passive voice: object becomes subject; is/are + past participle
• Direct to Indirect: shift reporting verb back one tense (says → said)
• Articles: use a before consonant sounds, an before vowel sounds, the for specificity
• Collective nouns take singular verbs in British English (The team is playing well)

Exam Tip: In error-spotting questions, look for subject-verb mismatches first, then article errors. Questions on “fill in the blank” often test prepositions and tenses. Memorise the 12 tenses with their signal words (e.g., already → present perfect, while → present continuous).

Parts of Speech — The Building Blocks

English has eight parts of speech, each serving a distinct grammatical function:

1. Noun — names a person, place, thing, or idea (captain, fort, weapon, courage)
2. Pronoun — replaces a noun (he, she, it, they, who, which)
3. Adjective — modifies a noun (brave soldier, Indian army)
4. Verb — expresses action or state (march, defend, is)
5. Adverb — modifies a verb, adjective, or another adverb (quickly, very, strongly)
6. Preposition — shows relationship between noun/pronoun and other words (in, on, at, by, for, from, to)
7. Conjunction — joins words, phrases, or clauses (and, but, or, because, although)
8. Interjection — expresses emotion (ah, hurrah, alas)

Tenses — Twelve Forms in Four Categories

Tense	Simple (Habitual)	Continuous (Ongoing)	Perfect (Past Result)	Perfect Continuous
Present	I play	I am playing	I have played	I have been playing
Past	I played	I was playing	I had played	I had been playing
Future	I will play	I will be playing	I will have played	I will have been playing

NDA questions frequently test present perfect vs past simple. Just, already, yet, recently, ever, never signal present perfect. Yesterday, ago, last week signal past simple.

Active and Passive Voice — Conversion Rules

Active: The army defeated the enemy. → Passive: The enemy was defeated by the army.

Tense	Active	Passive
Simple Present	The commander leads.	The commander is led.
Simple Past	The commander led.	The commander was led.
Present Perfect	The commander has led.	The commander has been led.
Future	The commander will lead.	The commander will be led.
Modal	The commander can lead.	The commander can be led.

Direct and Indirect Speech — Key Transformation Rules

1. Reporting verb changes back one tense: says → said, will say → would say
2. Pronouns change based on the speaker: I → he/she, we → they
3. Time words shift: now → then, today → that day, here → there, this → that
4. If reporting verb is in past tense, back-shift applies: “I am ready,” he said → He said that he was ready
5. Questions: use asked + if/whether; commands: use told + to-infinitive

Subject-Verb Agreement — Tricky Cases

• Collective nouns (army, crew, team, jury): singular verb in British English — The team is ready
• Either/or, neither/nor: verb agrees with the nearer subject — Either the soldiers or the captain is responsible
• Everyone, nobody, each: always singular — Everyone is present
• Number vs majority: can take singular or plural depending on meaning — The majority were/was in favour
• Indefinite pronouns (some, any, all): check the noun they refer to — Some of the water is cold

Articles — Rules and Exceptions

• A before consonant sounds: a soldier, a university (yu-ni-ver-si-ty begins with y as consonant sound)
• An before vowel sounds: an officer, an hour (h is silent)
• The for unique things (the sun, the moon), previously mentioned items, nationalities (the Indians), mountains and rivers (the Himalayas, the Ganga), and superlatives (the bravest)
• No article before names, days, months, meals: India won on Monday, in January, after breakfast

Prepositions — Usage Patterns

• In: countries, cities (in India, in Delhi), months, years, seasons, enclosed spaces
• On: dates, days, surfaces (on Monday, on the table), floors
• At: specific times (at 6 a.m.), addresses (at 5 Mahatma Gandhi Road), small places (at the station)
• By: methods/means (by train, by hand), near (by the river), comparison (by nature, by profession)
• For: duration, purpose (for two hours, for defence)
• From: origin (from India), separation (hide from)

• Through: movement across/in between (through the forest)
• During: time period (during the war)
• Among: more than two (among the soldiers)
• Between: exactly two (between India and Pakistan)

Common NDA errors: arrived at (not in) a place; interested in (not of); married to (not with).

Error Spotting — Systematic Approach

NDA error-spotting questions (often sentence correction type) require a methodical approach:

1. Check subject-verb agreement first — look for intervening phrases between subject and verb
2. Scan for article misuse — missing, extra, or wrong article
3. Examine preposition choice — standard collocations
4. Test tenses — sequence of tenses in complex sentences
5. Look for pronoun-antecedent mismatches — especially with collective nouns and indefinite pronouns
6. Check parallel structure — items in lists after “and” or “or” must be grammatically equal
7. Watch for dangling modifiers — participle phrases must clearly attach to the right subject
