Grammar is the system of rules that holds a language together. Think of it like traffic rules — without them, everyone crashes. When you understand grammar, sentences stop looking like random word-piles and start making structural sense.
For SSC GD, you are not writing an essay. You are recognising what sounds correct versus incorrect in a controlled, rule-governed way. That means you need a working knowledge of the eight parts of speech, the major tense structures, and the small connector words (prepositions, conjunctions) that SSC examiners love to test.
Here is the simplest mental model: every English sentence has at minimum a subject (who/what does something) and a predicate (what they do or are). Everything else — adjectives, adverbs, prepositions, articles — is support staff. The verb and its tense sit at the center of almost every grammar question you will face.
Think of a sentence as a cricket team. The verb is the captain — the entire team's function depends on the captain's form. Change the captain's role (present to past, active to passive) and the whole team realigns. Prepositions are the fielding positions — they tell you where a player is relative to the action. Get those positions wrong and the structure falls apart.
SSC GD questions at 10th-pass level test a small, predictable set of rules repeatedly. Across multiple years, the paper returns to: tense accuracy, correct preposition after common verbs/nouns, and pronoun case (who vs. whom). Master those three and you cover the majority of grammar marks.
Every word in English belongs to one (or sometimes more) of these categories:
| Part of Speech | Function | Example | |---|---|---| | Noun | Names a person, place, thing, idea | Delhi, courage, soldier | | Pronoun | Replaces a noun | he, she, who, whom | | Verb | Expresses action or state | writes, is, nominated | | Adjective | Describes a noun | long, multiple, ruling | | Adverb | Modifies verb/adjective/adverb | quickly, very, here | | Preposition | Shows relationship between noun and another element | for, since, as, in | | Conjunction | Joins words or clauses | and, but, because | | Interjection | Expresses emotion | oh, alas |
SSC GD rarely tests interjections. Focus your energy on verbs, prepositions, and pronouns.
There are three primary time zones: Present, Past, Future — each with four aspects (Simple, Continuous, Perfect, Perfect Continuous). That gives 12 tense forms. You do not need all 12 equally. These are the exam-critical ones:
Simple Past (subject + V2): Used for completed actions at a definite past time, especially historical facts.
Present Perfect (subject + has/have + V3): Used for actions that started in the past and continue to the present, or have recent relevance.
Future Simple (subject + will + V1): Used for predictions, decisions, or statements about future states.
Critical distinction — "for" vs. "since" with Perfect tenses:
for + duration (a period of time): for a long time, for three years, for two hourssince + point in time (a specific moment): since 2010, since Monday, since childhoodThis single rule explains one of the most repeated question types on SSC GD.
Prepositions show relationships. In SSC GD, they appear most often in fill-in-the-blank questions. The tricky ones are collocations — fixed combinations where a specific preposition follows a specific verb or noun regardless of pure logic.
Key collocations to know:
Look — the difference between "nominated as" and "nominated for" is exactly the kind of trap SSC GD sets. When the blank follows a noun that describes an identity or role (candidate, spokesperson, captain), use as. When the blank points to a prize or position being competed for, use for.
This is another recurring SSC GD pattern.
Quick test: replace "who/whom" in the clause with he/him.
Who taught you such lessons? → He taught you such lessons. → "He" fits → Who is correct. Whom did you call? → You called him. → "him" fits → Whom is correct.
Who taught you these lessons? — person, subject role → Who. Which shirt do you want? — selecting from options → Which.
When you see a blank after "has been / have been" followed by a time expression, check whether the time expression is a duration or a point.
Duration words: a long time, five years, two hours, ages → for Point words: Monday, 2018, childhood, birth → since
Micro-example: "He has been working ___ 2019." → 2019 is a point → since. "He has been working ___ three years." → three years is a duration → for.
Standard method (trying both options and reading): 20 seconds. This pattern recognition: 4 seconds.
Replace who/whom with he/him in the embedded clause, ignoring question-word inversion.
Step 1 — Rearrange: Who/Whom taught you? → He/him taught you. Step 2 — "He taught" sounds right; "him taught" is wrong → answer is Who.
That is 2 steps versus mentally parsing subject/object grammar, which takes 6–8 steps for most students. Saves roughly 20 seconds per question.
Certain words in the sentence signal the correct tense immediately. Memorise these triggers:
| Signal Word | Tense | |---|---| | yesterday, ago, last year, in 1990 | Simple Past | | for (duration), since (point) | Present/Past Perfect | | tomorrow, next week, will | Future Simple | | now, at this moment, currently | Present Continuous | | always, usually, every day | Simple Present |
Micro-example: "Shakespeare ___ this play." — No duration, no signal for present relevance, historical completed fact → Simple Past → wrote.
Using signal words cuts blank-filling time from 30 seconds (trying all options) to 8 seconds (spot the signal, match the tense).
Ask yourself: does the blank lead to a role/identity or a prize/competition?
Role/Identity → as: nominated as the party's candidate, appointed as captain Prize/Competition → for: nominated for the best actor award, shortlisted for the post
When a noun phrase like "the ruling party's candidate" follows the blank, it names an identity → use as. This eliminates three wrong options in 3 seconds flat instead of reading all four options fully.
To convert a Present Simple sentence to Future Simple:
Replace is/are/am with will be. Do not touch anything else in the sentence.
There are multiple facilities available. → There will be multiple facilities available.
Watch out: Options like "have been" (present perfect) or "had been" (past perfect) or "were" (simple past) look plausible but change the time zone. The word will is the only future marker here. 2-step check, no re-reading needed.
When you see a grammar fill-in-the-blank on SSC GD, run this decision tree in order:
Step 1 — Identify the blank's category. Is it asking for a preposition, a verb form, a pronoun, or a conjunction? The surrounding words tell you this in under 5 seconds.
Step 2 — Apply a signal-word scan. Look left and right of the blank for time words (yesterday, since, for, will), role-words (as, for), or question starters (who, whom, what, which).
Step 3 — Apply the matching rule. Duration → "for". Point in time → "since". Subject role in question → "who". Historical completed action → Simple Past (V2). Future state → "will be".
Step 4 — Eliminate using grammar, not ear. Do not pick an answer because it "sounds right" — that instinct was formed in your first language and often misfires. Use the rule. Eliminate options that violate the rule, even if they feel comfortable.
Step 5 — Confirm in 5 seconds. Re-read the complete sentence with your chosen option. If the sentence is grammatically complete and the meaning makes sense, confirm and move on. Do not second-guess.
Total time per question: 30–45 seconds maximum.
Why this question: Tests the classic "for vs. since" distinction that reappears across multiple SSC GD years. The trigger is the Present Perfect Continuous tense ("has been staying") combined with a time expression.
Solving path: "Has been staying" is Present Perfect Continuous — it describes an action ongoing from the past to now. "A long time" is a duration (not a specific point). Duration → for. Eliminate: "from" (not used with Perfect tenses for duration), "till" (means up to a point), "since" (needs a specific point, not a duration). Answer: for.
Why this question: Tests the "nominated as vs. nominated for" collocation — one of SSC GD's favourite preposition traps. The phrase following the blank is "the ruling party's candidate for the post," which names an identity/role.
Solving path: The blank is followed by "the ruling party's candidate" — a noun phrase naming a specific role. When the word after the preposition names an identity or designation, use as. "For" would imply competition for a prize rather than designation to a role. "In" and "to" do not collocate with "nominated." Answer: as.
Why this question: Tests the who/whom distinction using an interrogative sentence — one of the most mishandled pronoun questions at 10th-pass level.
Solving path: Apply the He/Him substitution test. Rearrange: "___ taught you such lessons?" → "He/him taught you." → "He taught you" is grammatically correct; "him taught you" is not. → Subject role → Who. "What" asks about things, not people. "Which" asks for selection from a set. "Whom" is object case — wrong here. Answer: Who.
Why this question: Tests tense selection for historical facts — a very common verb-form question where students incorrectly choose Present tenses for completed past events.
Solving path: Shakespeare is a historical figure — the act of writing this play is a completed action at a definite past time. No time expression linking it to the present exists in the sentence. That rules out Present Perfect ("has written") and Present Continuous ("is writing"). "Write" (base form) is wrong because the subject "Shakespeare" needs a conjugated verb. Simple Past ("wrote") handles a completed past action with no present relevance. Answer: wrote.
Why this question: Tests future tense conversion — a question type introduced in recent SSC GD papers requiring students to recognise the correct future form among look-alike options (have been, had been, were).
Solving path: The task is to convert to future tense. The original sentence uses "are" (Present Simple). The only option that introduces a future marker is "will be." Check the other options: "have been" = Present Perfect (past-to-present), "had been" = Past Perfect (further-past-to-past), "were" = Simple Past. Only "will be" moves the time zone to the future. Replace "are" with "will be" and nothing else changes. Answer: There will be multiple facilities available for reaching the island.
Using "since" with a duration: Writing "He has been here since three years" is incorrect. "Three years" is a duration — it demands "for." "Since" must follow a specific point in time (since 2020, since Monday).
Choosing "whom" when the pronoun is the subject: In "Whom called you?" the pronoun is the subject of "called," so it must be "Who." Do not use "whom" just because the sentence is a question — test the subject/object role.
Using Present Perfect for clearly historical events: "Shakespeare has written this play" is wrong. He is not alive; there is no present connection. Past Simple is mandatory for completed actions at a definite past time. The presence of "has/have" feels formal and therefore "correct" to many students — resist that instinct.
Confusing "nominated for" and "nominated as": "Nominated for the candidate" is wrong because "candidate" is a role, not a prize. Use "nominated as the candidate" (role assignment) and "nominated for the award" (prize competition).
Using "what" instead of "who" for persons: "What taught you?" is grammatically wrong when asking about a person. "What" is for things, qualities, or identities in abstract. "Who" is always used when the subject or object is a person.
Choosing "were" when asked to convert to future tense: "Were" is Simple Past. In conversion questions, students sometimes pick the "different-from-the-original" option reflexively. Always verify that the option actually places the action in the future, not just in a different past form.
