Introduction
If Unseen Prose is about applying grammar inside an unfamiliar passage, this sub-topic — plain "Grammar" — is about the rules themselves: the actual structures of English (tenses, parts of speech, agreement, voice, narration) tested directly, usually through standalone sentences, fill-in-the-blank items, or "spot the error" questions, without needing a passage around them. A beginner should also not confuse this with the Pedagogy topic's separate sub-topic on the "critical perspective on the role of grammar" — that sub-topic debates how and whether grammar should be taught explicitly in a classroom; this sub-topic is simply about knowing the grammar rules correctly, since it is, per the CG syllabus's own mark-analysis, the single heaviest-weighted component of the entire English paper.
For a beginner, grammar often feels like an intimidating pile of unconnected rules — twelve tenses, eight parts of speech, articles, prepositions, active-passive, direct-indirect. The good news is that almost all competitive-exam grammar questions recycle the same handful of rule categories again and again, in slightly different sentences. Learning the categories well, rather than memorising isolated example sentences, is what actually transfers to a new question on exam day.
Detailed Explanation
Background basics
- Grammar — the set of rules that govern how words combine to form correct, meaningful sentences in a language.
- Parts of speech — the eight traditional categories every English word falls into, based on its role in a sentence: noun, pronoun, verb, adjective, adverb, preposition, conjunction, interjection.
- Tense — the grammatical form of a verb that shows when an action happens (past, present, future) and its aspect (simple, continuous, perfect, perfect continuous).
- Voice — whether the subject of a sentence performs the action (active voice) or receives the action (passive voice).
- Narration — whether someone's exact words are quoted directly (direct speech) or reported in one's own words (indirect/reported speech).
The eight parts of speech (quick reference)
- Noun — names a person, place, thing, or idea (Raipur, teacher, honesty).
- Pronoun — replaces a noun (he, she, it, they, who).
- Verb — expresses an action or state (run, is, seems).
- Adjective — describes a noun (tall, blue, three).
- Adverb — describes a verb, adjective, or another adverb, often answering how/when/where (quickly, very, yesterday).
- Preposition — shows the relationship of a noun/pronoun to another word (in, on, under, before).
- Conjunction — joins words, phrases, or clauses (and, but, because, although).
- Interjection — expresses sudden emotion (Wow!, Alas!, Oh!).
The twelve tenses
Each of the three time-frames (past, present, future) has four aspects (simple, continuous, perfect, perfect continuous), giving twelve total tense forms:
- Present simple — "She teaches every day." (habitual/general fact)
- Present continuous — "She is teaching right now." (ongoing action)
- Present perfect — "She has taught for ten years." (past action with present relevance)
- Present perfect continuous — "She has been teaching since morning." (ongoing action started in the past, continuing now)
- Past simple — "She taught yesterday." (completed past action)
- Past continuous — "She was teaching when the bell rang." (ongoing past action interrupted by another)
- Past perfect — "She had taught before she became principal." (action completed before another past action)
- Past perfect continuous — "She had been teaching for years before she retired." (ongoing action up to a point in the past)
- Future simple — "She will teach tomorrow." (a simple future action)
- Future continuous — "She will be teaching at 10 a.m." (an action ongoing at a specific future time)
- Future perfect — "She will have taught the full syllabus by March." (action completed before a future point)
- Future perfect continuous — "By next year, she will have been teaching for twenty years." (ongoing action continuing up to a future point)
Subject-verb agreement
- The verb must agree in number (singular/plural) with its subject: "The teacher writes" (singular) vs. "The teachers write" (plural).
- A subject joined by "and" usually takes a plural verb: "Ramesh and Suresh are friends."
- Collective nouns (team, class, family) usually take a singular verb when treated as one unit: "The class is attentive."
- Subjects joined by "or"/"nor" agree with the noun closest to the verb: "Neither the teacher nor the students were ready" (verb agrees with "students," the nearer subject).
Articles
- "A" is used before words beginning with a consonant sound (a book, a university — "university" starts with a consonant sound "yoo").
- "An" is used before words beginning with a vowel sound (an apple, an hour — "hour" starts with a vowel sound since "h" is silent).
- "The" is used for something specific/already known, or for unique things: "the sun," "the Mahanadi river," "the Chief Minister of Chhattisgarh."
- No article is generally used before plural/uncountable nouns used in a general sense ("Teachers work hard," not "The teachers work hard," when speaking of teachers in general).
Prepositions
- In — used for larger enclosed spaces or longer time periods ("in Raipur," "in August").
- On — used for surfaces or specific days/dates ("on the table," "on Monday").
- At — used for specific points (places or exact times) ("at the station," "at 5 o'clock").
- Between — used for exactly two items ("between the two villages").
- Among — used for more than two ("among the tribal communities of Bastar").
Voice: active and passive
- Active voice — the subject performs the action: "The teacher explains the lesson."
- Passive voice — the subject receives the action, formed with a form of "be" + past participle: "The lesson is explained by the teacher."
- Only transitive verbs (verbs that take an object) can be made passive — "She sleeps" has no object, so it cannot be converted to passive voice.
- Tense is preserved during conversion: an active present-simple sentence becomes a passive present-simple sentence, not a different tense.
Narration: direct and indirect speech
- Direct speech quotes the exact words spoken, in quotation marks: Ramesh said, "I am going to school."
- Indirect (reported) speech reports the content in the speaker's own words, without quotation marks, and usually requires three changes: (1) tense shift (back one step — present becomes past, e.g., "am" → "was"), (2) pronoun shift (matching the new speaker's perspective, e.g., "I" → "he"), and (3) time/place-word shift (e.g., "today" → "that day," "here" → "there"). Example: Ramesh said that he was going to school.
Degrees of comparison
- Positive — the base form, no comparison: "Raipur is a big city."
- Comparative — comparing two things, usually with "-er" or "more": "Raipur is bigger than Kanker."
- Superlative — comparing three or more, usually with "-est" or "most": "Raipur is the biggest city in this comparison."
Error detection / correction
A very common competitive-exam question format presents a sentence divided into parts and asks the candidate to identify which part (if any) contains a grammatical error — this format tests all the categories above simultaneously, since an error could involve tense, agreement, article, preposition, or voice.
Practical relevance for a teacher
A teacher's own grammatical accuracy directly shapes the "input" children receive — if a teacher habitually makes subject-verb agreement errors on the blackboard, children absorb those errors as correct models. Beyond personal accuracy, understanding why a rule works (not just that it exists) lets a teacher explain a correction meaningfully when a child asks "why is it wrong?" instead of only saying "because it just is."
How the categories interconnect
Grammar categories rarely appear alone in a real sentence — a single well-formed sentence usually draws on several rules working together correctly.
- Worked example: "Neither the headmaster nor the teachers were present at the meeting held in Bilaspur on Monday." This one sentence correctly applies subject-verb agreement (neither/nor → agree with nearer plural "teachers"), the definite article ("the" meeting — a specific, known meeting), and two different prepositions ("in" for the city, "on" for the specific day).
- Worked example — active to passive with tense preserved: Active: "The Chief Minister inaugurated the new school in Jagdalpur." (past simple) → Passive: "The new school in Jagdalpur was inaugurated by the Chief Minister." (past simple passive — "was" + past participle, tense preserved, not shifted to present or future).
- Worked example — narration with all three shifts: Direct: The student said, "I am studying here for my exam today." → Indirect: The student said that he was studying there for his exam that day. (tense shift: am→was; pronoun shift: I/my→he/his; place/time shift: here→there, today→that day — all three rules applied together in one conversion).
- Worked example — error-detection combining categories: Sentence: "She don't like the tea which was made by her friends yesterday." The error is in "don't," which should be "doesn't" (subject-verb agreement — "she" is singular, third person), while the article, preposition, and passive-voice construction elsewhere in the sentence are all correct — showing that error-detection requires checking every category, not assuming the whole sentence is wrong.
Why this matters for the exam
Grammar (tested here as standalone rule-based content) is the single largest-weighted component of the CG Sahayak Shikshak English paper according to exam-prep mark analysis of the cgssb.in syllabus — reportedly around 14 of roughly 25 English marks, more than comprehension and vocabulary combined. It is also the direct foundation for the "grammar-in-context" questions inside the separate Unseen Prose sub-topic, so mastering these rules in isolation first makes the applied passage-based questions far easier.
Memory aid
Tense mnemonic — "When did it happen, and is it still going?" Ask two questions for any tense: (1) When — past, present, or future? (2) Is it ongoing (continuous), finished-with-present-relevance (perfect), or both (perfect continuous)? Combining the answers to these two questions gives you the correct one of the twelve tenses every time, rather than memorising twelve forms as separate unrelated facts.
Narration mnemonic — "TPT": Tense, Pronoun, Time/place — the three things that shift when direct speech becomes indirect speech.
Worked Examples
- Tense identification. "By the time we reached the station, the train had already left." → Past perfect (action completed before another past action — our reaching the station).
- Subject-verb agreement. Correct the sentence: "Each of the students have submitted their assignment." → Each of the students has submitted — "each" is singular, even though it's followed by a plural noun ("students").
- Articles. Fill in the blank: "___ European country I visited was ___ honest and welcoming place." → A European country (consonant sound "yoo"); an honest place (silent "h," vowel sound).
- Voice conversion. Convert to passive: "The Governor of Chhattisgarh will inaugurate the new library." → The new library will be inaugurated by the Governor of Chhattisgarh.
- CG-specific — narration. Convert to indirect speech: The tourist guide in Chitrakote said, "This waterfall is at its most powerful now, during the monsoon." → The tourist guide in Chitrakote said that that waterfall was at its most powerful then/at that time, during the monsoon. (tense shift: is→was; "this"→"that"; "now"→"then").
- CG-specific — prepositions. Fill in the blanks: "The Bastar Dussehra celebrations take place ___ October, usually ___ the main square ___ Jagdalpur." → in October (month), in the main square (enclosed space), in Jagdalpur (city) — note all three could plausibly use "in," while "at the main square" is also acceptable for a specific point; competitive papers test the more common convention.
- CG-specific — degrees of comparison. "The Chitrakote Falls are ___ (powerful) during the monsoon than in summer." → more powerful (comparative, since only two seasons are being compared).
- CG-specific — error detection. Identify the error: "The farmers of Kanker has grown paddy for generations, and they continues to use traditional methods." → Two errors: "has" should be "have" (farmers is plural), and "continues" should be "continue" (plural subject "they").
- Harder — active-passive with modal verb. Convert to passive: "The government must complete the new road project by next year." → The new road project must be completed by the government by next year. (modal verb "must" retained, "be + past participle" used for the passive).
- Hardest — multi-rule sentence correction. Correct all errors in: "Neither the Principal nor the teacher were informed about a unusual incident which occur in the school yesterday." → Neither the Principal nor the teacher was informed about an unusual incident which occurred in the school yesterday. (three corrections: were→was, since "teacher," the nearer subject, is singular; a→an, before the vowel sound "unusual"; occur→occurred, since the sentence is in past tense throughout).

Common Mistakes / Misconceptions
- Mistake: Applying subject-verb agreement based on the noun closest to the subject rather than the true grammatical subject. Correction: As in Worked Example 2, "each of the students" is grammatically singular ("each"), regardless of the plural noun ("students") that follows.
- Mistake: Choosing "a" or "an" based on the written first letter rather than the actual first sound. Correction: "An hour" (silent h, vowel sound) and "a university" (consonant "yoo" sound) — always judge by sound, not spelling.
- Mistake: Forgetting to preserve the original tense when converting active to passive voice. Correction: As in Worked Example 4, a future-simple active sentence must become a future-simple passive sentence, not shift to a different tense.
- Mistake: Converting only the verb's tense in direct-to-indirect narration and forgetting the accompanying pronoun and time/place-word shifts. Correction: Always check all three (tense, pronoun, time/place), as shown in the TPT mnemonic and Worked Example 5.
- Mistake: Assuming every verb can be converted to passive voice. Correction: Only transitive verbs (verbs with a direct object) can be made passive; intransitive verbs like "sleep," "arrive," or "die" (without an object) cannot.
- Mistake: Treating "between" and "among" as interchangeable. Correction: "Between" is for exactly two items/people; "among" is for three or more, as in "among the tribal communities of Bastar."
- Mistake: In error-detection questions, assuming an error must exist somewhere and forcing a choice even when the sentence is correct. Correction: Many competitive papers include a "no error" option; a well-formed sentence with correct grammar throughout should be marked as having no error.
- Mistake: Confusing comparative and superlative forms when only two items are being compared. Correction: As in Worked Example 7, comparing only two things always requires the comparative ("more powerful"), never the superlative ("most powerful").
Previous Year Question Pattern
A CG-specific, exam-year-cited solved grammar paper for the Sahayak Shikshak exam could not be independently verified from publicly available sources at the time of writing — CGSSB's portal confirms the syllabus and approximate mark weightage (grammar ≈ 14 marks, the largest English component) but not a downloadable solved past paper broken down by rule category; this is stated honestly rather than inventing a citation. Falling back to the well-documented national CTET/State-TET pattern, which this sub-topic closely mirrors:
- CTET Paper 1 & 2 (recurring across cycles) consistently include standalone grammar questions on tense, subject-verb agreement, articles, and prepositions, independent of any passage — confirming this "rules in isolation" format (as distinct from grammar-in-context questions inside a passage) is a standard, recurring component.
- Recurring error-detection format: CTET-style and various State-TET papers regularly include "spot the error" questions where a sentence is split into segments (often underlined or lettered) and the candidate must identify the segment with a grammatical mistake — directly matching the error-detection format highlighted in this article.
- Recurring active-passive and narration conversion format: direct sentence-transformation questions ("convert to passive voice," "convert to indirect speech") appear regularly across CTET-aligned and state competitive-exam grammar sections, testing the same rule sets (tense preservation, TPT shifts) covered above.
Practice MCQs
- Which part of speech describes a noun? (a) Verb (b) Adjective (c) Preposition (d) Conjunction → (b).
- "She has been teaching since morning" is an example of which tense? (a) Present perfect (b) Present perfect continuous (c) Past continuous (d) Present continuous → (b).
- Choose the correctly completed sentence: "Neither the teacher nor the students ___ ready." (a) is (b) am (c) were (d) has → (c) — the verb agrees with "students," the subject closer to the verb.
- "___ hour is enough to finish this test." Which article fits? (a) A (b) An (c) The (d) No article needed → (b) — "hour" begins with a silent "h," so it starts with a vowel sound.
- Convert to passive voice: "The teacher explains the lesson." (a) The lesson explains the teacher (b) The lesson is explained by the teacher (c) The lesson was explained by the teacher (d) The lesson will be explained by the teacher → (b) — present simple active becomes present simple passive.
- Which sentence uses "between" correctly? (a) The land is divided between the three brothers (b) The land is divided between the two brothers (c) Choose between all these options (d) Among the two of us → (b) — "between" is for exactly two.
- Convert to indirect speech: Ramesh said, "I am going to Raipur today." (a) Ramesh said that I am going to Raipur today (b) Ramesh said that he is going to Raipur today (c) Ramesh said that he was going to Raipur that day (d) Ramesh said I was going to Raipur today → (c) — requires all three shifts: tense, pronoun, and time word.
- Which verb CANNOT be correctly converted into the passive voice? (a) explains (b) sleeps (c) built (d) is teaching → (b) — "sleeps" is intransitive (no object), so it cannot be made passive.
- "Raipur is ___ than Kanker in population." Which form is correct? (a) big (b) bigger (c) biggest (d) most big → (b) — comparative form, since exactly two cities are being compared.
- Identify the error: "The farmers of Kanker has grown paddy for generations." (a) farmers (b) has (c) grown (d) generations → (b) — should be "have," since "farmers" is plural.
- Which preposition correctly completes: "The meeting was held ___ the main hall ___ Monday morning."? (a) in / on (b) on / in (c) at / at (d) between / among → (a) — "in" for an enclosed space, "on" for a specific day.
- "By next year, she ___ teaching for twenty years." Which tense correctly completes this sentence? (a) will teach (b) has taught (c) will have been teaching (d) was teaching → (c) — future perfect continuous, an ongoing action continuing up to a future point.
- Which sentence correctly uses "among"? (a) Among the two villages, one had better roads (b) The prize was shared among the three winners (c) Between the five candidates, she scored highest (d) Choose among these two options → (b) — "among" correctly used for more than two (three winners).
- Identify the error: "Neither the Principal nor the teacher were informed about an unusual incident." (a) Neither...nor (b) were (c) an (d) unusual → (b) — should be "was," since "teacher," the nearer subject, is singular.
- Why do error-detection questions require checking every grammar category in a sentence rather than assuming one obvious category is wrong? (a) Because errors are always in the first word (b) Because a sentence can contain a correctly-formed structure in most categories with an error hidden in just one (c) Because there is never more than one type of error (d) Because grammar categories don't interact → (b) — as shown in Worked Example 4, most of a sentence can be correct with the error confined to just one specific category.
Summary / Quick Revision Points
- Grammar (this sub-topic) tests rules directly, through standalone sentences — distinct from Unseen Prose's grammar-in-context questions and from the Pedagogy topic's debate over how grammar should be taught.
- Eight parts of speech: noun, pronoun, verb, adjective, adverb, preposition, conjunction, interjection.
- Twelve tenses = 3 time-frames (past/present/future) × 4 aspects (simple/continuous/perfect/perfect continuous).
- Subject-verb agreement follows the true grammatical subject (e.g., "each," "neither...nor" + nearer noun), not just the nearest plural-looking word.
- "A"/"an" depend on the initial sound, not the written first letter (an hour, a university).
- Only transitive verbs (verbs with an object) can be converted to passive voice; tense must be preserved during conversion.
- Indirect speech requires three shifts, remembered by "TPT": Tense (back one step), Pronoun (perspective), Time/place words.
- "Between" is for exactly two items; "among" is for three or more.
- Comparative form is used for exactly two items; superlative for three or more.
- Error-detection questions test all categories at once — most of a sentence may be correct, with the error confined to a single spot.
- Grammar (≈14 marks per cgssb.in-based estimates) is the single heaviest-weighted component of the English paper.
- CG-specific PYQ citations for this sub-topic were not independently verifiable; the national CTET pattern (standalone grammar items, error-detection, sentence transformation) is the closest confirmed reference.
Check Yourself
- Can you list all eight parts of speech and give one original example of each?
- Given any English sentence, can you correctly name its tense using the "when + is it ongoing/finished" two-question method?
- Can you explain why "each of the students" takes a singular verb even though "students" is plural?
- Could you correctly convert a sentence from active to passive voice while preserving its original tense?
- Can you list, from memory, the three shifts required when converting direct speech to indirect speech (TPT)?
- Given a short sentence with one hidden grammar error, could you identify exactly which word or phrase is wrong, and explain why?
