Master Conjunctions for SSC

Welcome to the "Free Marks" chapter. Conjunctions are deeply mathematical. If you learn the specific Correlative Pairs and the Rule of Inversion, you can spot the error in exactly 2 seconds without even translating the sentence. Let's decode the examiner's logic.

๐Ÿค–
"Hello future officers! A conjunction is simply a joining word. It acts like glue to stick two words, phrases, or clauses together. But SSC won't test simple words like 'and' or 'but'. They will test 'Jealous Pairs'โ€”like how 'Hardly' ONLY pairs with 'When'. They will also test the dreaded 'Rule of Inversion'. Let's dive in!"

Basics: The 3 Types of Grammar "Glue"

๐Ÿ”Š Listen: Understanding Clauses & FANBOYS

What does a Conjunction actually do?

Unlike prepositions (which show relationships like time or place), conjunctions are purely connectors. They hold the sentence structure together. If a sentence is a train, conjunctions are the metal links holding the bogies (clauses) together. There are exactly 3 types of grammar glue.

Type 1: Coordinating Conjunctions (FANBOYS)

These join two items of equal grammatical rank. This means they connect a Noun to a Noun, an Adjective to an Adjective, or an Independent Clause to an Independent Clause. Memorize the famous acronym FANBOYS:

LetterConjunctionMeaning & UseExample
FForBecause / ReasonI drank water, for I was thirsty.
AAndAddition / PlusHe bought a pen and a book.
NNorNegative AdditionHe doesn't eat meat, nor does he drink milk.
BButDirect ContrastHe is poor, but he is honest.
OOrChoice / OptionYou can have tea or coffee.
YYetSurprising ContrastHe studied hard, yet he failed.
SSoResult / ThereforeIt was raining, so I stayed home.

๐Ÿšจ SSC Trap: Is "For" a Preposition or a Conjunction?

The word For plays a double role in English grammar.
โ€ข If it is followed directly by a Noun or Time duration (e.g., for 2 hours, for you), it is acting as a Preposition.
โ€ข If it is followed by a full sentence/clause containing a Subject + Verb, it is acting as a Conjunction meaning "because" (e.g., I went to bed, for I was tired).

Type 2: Subordinating Conjunctions (The Boss & Employee)

These conjunctions are used to join an Independent Clause (The Boss: a complete sentence that makes sense alone) to a Dependent Clause (The Employee: an incomplete thought that needs the boss to survive).

โฑ๏ธ 1. Conjunctions of TIME

Words: When, While, After, Before, Until, Since, As soon as.

Sequence
โœ… The patient had died before the doctor arrived.
(Establishes the timeline of two past actions).
Immediate Action
โœ… As soon as the bell rang, the students rushed out.
(The dependent employee clause can come first if separated by a comma).

๐Ÿค” 2. Conjunctions of REASON/CAUSE

Words: Because, Since, As.

Direct Reason
โœ… I will stay at home because it is raining.
(Boss: "I will stay at home." Employee gives reason: "because it is raining").
SSC Favorite ('Since')
โœ… Since you are my senior, I will follow your advice.
(Here 'Since' means 'because', it does not mean 'time from the past').

โš–๏ธ 3. Conjunctions of CONDITION

Words: If, Unless, Provided that, In case.

Negative Condition
โœ… You will fail unless you study hard.
(Boss: "You will fail." Condition: "unless you study" - which means 'if not').
Strict Condition
โœ… I will lend you money provided that you return it by Monday.
('Provided that' means strictly 'on the condition that').

๐Ÿ”„ 4. Conjunctions of CONTRAST

Words: Although, Even though, Though, Whereas.

Unexpected Result
โœ… Although he was tired, he kept walking.
(Shows a result that contradicts the situation).
Direct Comparison
โœ… Ram is hardworking, whereas his brother is lazy.
(Used to directly contrast two different subjects).

๐ŸŽฏ 5. Conjunctions of PURPOSE

Words: So that, In order that, Lest.

Positive Purpose
โœ… Speak clearly so that everyone can hear you.
(Explains the 'why/goal' behind the action).
Negative Purpose
โœ… Walk carefully lest you should fall.
('Lest' is a negative purpose meaning 'so that... not').

Type 3: Correlative Conjunctions (The Jealous Pairs)

These are the VIPs of SSC Exams. They are multi-word conjunctions that always travel in pairs (e.g., Either...or, Not only...but also). They are extremely jealous and never accept a different partner. We will dedicate the entire next section to mastering their traps!

Correlatives & The Scales of Justice

๐Ÿ”Š Listen: Jealous Pairs & Parallelism

๐Ÿง  Teacher's Hack: The "Jealous Pairs"

Correlative conjunctions (Type 3) are words that ALWAYS work in pairs. Think of them as strictly married couples. They are extremely jealous; they will never accept a different partner.

If you see "No sooner", your eyes must immediately scan the sentence to find its true partner "than". If the examiner has written "when" or "then", mark the error instantly!

The First Word The ONLY Correct Partner The SSC Trap Word
No sooner... than... when / then
Hardly / Scarcely... when (or before)... than / then
Not only... but also... but / and also
Although / Though... yet (or a comma ',')... but / and
Both... and... as well as / or
Between... and... to
Whether... or... that / if
Lest... should... may / will / should not
From... to... and
Else / Other... than... but

๐Ÿšจ SSC Master Traps: All 10 Pairs

Scroll down to see exactly how SSC swaps the correct partners to force a negative mark.

Pair 1
โŒ No sooner had he arrived when it started raining.
Correct
โœ… No sooner had he arrived than it started raining.
(No sooner ALWAYS takes 'than' with an 'a').
Pair 2
โŒ Scarcely had she finished the exam than the bell rang.
Correct
โœ… Scarcely had she finished the exam when the bell rang.
(Hardly/Scarcely ALWAYS take 'when').
Pair 3
โŒ He is not only smart but brave.
Correct
โœ… He is not only smart but also brave.
(The pair must be complete. Do not drop 'also').
Pair 4
โŒ Although he is poor, but he is honest.
Correct
โœ… Although he is poor, yet he is honest.
(Although takes 'yet' or just a comma, never 'but').
Pair 5
โŒ Both Ram as well as Shyam went there.
Correct
โœ… Both Ram and Shyam went there.
(Both ONLY pairs with 'and'. This is a massive SSC favorite).
Pair 6
โŒ The shop is closed between 2 PM to 4 PM.
Correct
โœ… The shop is closed between 2 PM and 4 PM.
(Between is paired with 'and'. 'From' is paired with 'to').
Pair 7
โŒ I don't know if he will come or not.
Correct
โœ… I don't know whether he will come or not.
(When offering a choice with 'or', use 'whether', not 'if').
Pair 8
โŒ Work hard lest you will fail.
Correct
โœ… Work hard lest you should fail.
(Lest ONLY accepts the modal 'should').
Pair 9
โŒ The class runs from Monday and Friday.
Correct
โœ… The class runs from Monday to Friday.
(From pairs with 'to'. Between pairs with 'and').
Pair 10
โŒ He has no other option but to resign.
Correct
โœ… He has no other option than to resign.
(Other and Rather are followed by 'than'. 'Nothing else' is followed by 'but').

โš–๏ธ The "Scales of Justice" (Parallel Structure)

Correlative conjunctions (Not only...but also, Either...or, Both...and) act like a weighing scale. The grammatical form placed immediately after the first part MUST be exactly the same as the grammatical form after the second part.

Not only + [Noun] ... But also + [Noun] โœ…
Not only + [Verb] ... But also + [Noun] โŒ

Trap
โŒ He not only speaks English but also French.
(Not only + Verb 'speaks'. But also + Noun 'French'. The scale is unbalanced!)
Correct
โœ… He speaks not only English but also French.
(Not only + Noun. But also + Noun. Perfectly balanced!).
Trap
โŒ Either he will go to Delhi or Mumbai.
Correct
โœ… He will go either to Delhi or to Mumbai.
(Either + Preposition 'to'. Or + Preposition 'to').

The Rule of Inversion (CGL Mains Level)

๐Ÿ”Š Listen: How to Master Inversion

The Rule of Inversion (CGL Mains Level)

๐Ÿ”Š Listen: How to Master Inversion

What is Inversion? (The Question Mark Analogy)

Normally, an English sentence flows straight: Subject + Helping Verb + Main Verb (e.g., He had gone).

However, if a sentence STARTS with a Negative Word or a Negative Conjunction, the grammar panics! It flips exactly like an Interrogative (Question) sentence: Helping Verb + Subject + Main Verb.

๐Ÿšจ The Inversion Trigger Words:
No Sooner, Hardly, Scarcely, Seldom, Never, Barely, Not Only, Under no circumstances.

SSC TRAP FORMAT (Wrong):
[Negative Start] โž” Subject โž” Verb ...
โŒ No sooner he saw the tiger than he ran.


INVERSION FORMAT (Correct):
[Negative Start] โž” Helping Verb (did/had/does) โž” Subject โž” Main Verb ...
โœ… No sooner did he see the tiger than he ran.

๐Ÿง  Teacher's Hack: The "Verb Extraction" Rule

If the sentence already has a helping verb like "had" or "was", just pull it to the front. But what if the sentence only has a main verb (like went, plays, write)? You must DIG OUT the hidden helping verb (Do/Does/Did)!

  • If V2 (Past Tense): Extract DID + V1 (e.g., He arrived โž” did he arrive)
  • If V1+s/es (Singular Present): Extract DOES + V1 (e.g., He goes โž” does he go)
  • If V1 (Plural Present): Extract DO + V1 (e.g., They play โž” do they play)

CRITICAL WARNING: Once you extract 'did' or 'does', the main verb MUST revert to its pure V1 form! Never say "did he saw"!

The Inversion Example Bank

Trap 1
โŒ Hardly I had reached the station when it rained.
Correct
โœ… Hardly had I reached the station when it rained.
(เคนเคฟเค‚เคฆเฅ€: เคฎเฅˆเค‚ เคฎเฅเคถเฅเค•เคฟเคฒ เคธเฅ‡ เคธเฅเคŸเฅ‡เคถเคจ เคชเคนเฅเคเคšเคพ เคนเฅ€ เคฅเคพ เค•เคฟ เคฌเคพเคฐเคฟเคถ เคนเฅ‹เคจเฅ‡ เคฒเค—เฅ€เฅค)

The 10 Deadly SSC Conjunction Traps

๐Ÿ”Š Listen: Beat the Examiner's Tricks

๐Ÿšจ Trap 1: The "Lest" Negative Trap

The word "Lest" translates to "เค•เคนเฅ€เค‚ เคเคธเคพ เคจ เคนเฅ‹ เค•เคฟ" (otherwise / so that not). Because it carries a warning of a negative outcome, it is a Negative Word by birth.

  • Rule A (The Partner): It ONLY accepts the modal 'should'. Never use will, would, or may with it.
  • Rule B (The Double Negative): Because "Lest" already means "not", you can NEVER put "NOT" in the same clause!
Trap
โŒ Run fast, lest you will miss the train.
Correct
โœ… Run fast, lest you should miss the train.
(เคนเคฟเค‚เคฆเฅ€: เคคเฅ‡เคœเคผ เคฆเฅŒเคกเคผเฅ‹, เค•เคนเฅ€เค‚ เคเคธเคพ เคจ เคนเฅ‹ เค•เคฟ เคคเฅเคฎเฅเคนเคพเคฐเฅ€ เคŸเฅเคฐเฅ‡เคจ เค›เฅ‚เคŸ เคœเคพเคเฅค)
Trap
โŒ Work hard, lest you should not fail.
Correct
โœ… Work hard, lest you should fail.
(เคนเคฟเค‚เคฆเฅ€: เค•เคกเคผเฅ€ เคฎเฅ‡เคนเคจเคค เค•เคฐเฅ‹, เค•เคนเฅ€เค‚ เคเคธเคพ เคจ เคนเฅ‹ เค•เคฟ เคคเฅเคฎ เคซเฅ‡เคฒ เคนเฅ‹ เคœเคพเค“เฅค)
(Double negative error. Remove 'not').

๐Ÿšจ Trap 2: Until vs. Unless & The "No WILL/NOT" Rule

Until answers "Up to what time?" (เคœเคฌ เคคเค• เคธเคฎเคฏ).
Unless answers "Under what condition?" (เคฏเคฆเคฟ เคจเคนเฅ€เค‚ / เคœเคฌ เคคเค• เคถเคฐเฅเคค เคชเฅ‚เคฐเฅ€ เคจ เคนเฅ‹).

The VVIP Rule: Both words are inherently negative. You can NEVER put "NOT" or a future tense modal (Will/Shall/Would) inside the clause that starts with Until or Unless.

Time Trap
โŒ Wait here unless I return.
Correct
โœ… Wait here until I return.
(เคนเคฟเค‚เคฆเฅ€: เคฏเคนเคพเค เคคเคฌ เคคเค• เคชเฅเคฐเคคเฅ€เค•เฅเคทเคพ เค•เคฐเฅ‡เค‚ เคœเคฌ เคคเค• เคฎเฅˆเค‚ เคตเคพเคชเคธ เคจ เค† เคœเคพเคŠเคเฅค)
(Waiting is about Time, so use 'Until').
Negative Trap
โŒ Unless you do not study, you will fail.
Correct
โœ… Unless you study, you will fail.
(เคนเคฟเค‚เคฆเฅ€: เคœเคฌ เคคเค• เคคเฅเคฎ เคชเคขเคผเคพเคˆ เคจเคนเฅ€เค‚ เค•เคฐเฅ‹เค—เฅ‡, เคคเฅเคฎ เคซเฅ‡เคฒ เคนเฅ‹ เคœเคพเค“เค—เฅ‡เฅค)
Future Trap
โŒ Unless you will work hard, you will fail.
Correct
โœ… Unless you work hard, you will fail.
(Drop 'will' from the condition clause).

๐Ÿšจ Trap 3: The Reason Redundancy Error

The Mother Tongue Trap:

In Hindi, it is perfectly natural to say "เคšเฅ‚เค‚เค•เคฟ เคตเคน เคฌเฅ€เคฎเคพเคฐ เคฅเคพ, เค‡เคธเคฒเคฟเค เคตเคน เคจเคนเฅ€เค‚ เค†เคฏเคพเฅค" But English hates repetition!
If a sentence starts with As, Since, Because, or Due to (which already show reason), you can NEVER use Therefore, So, or Thus (เค‡เคธเคฒเคฟเค) in the second half of the sentence.

โŒ Since he was ill, therefore he didn't come.
โœ… Since he was ill, he didn't come.
(เคนเคฟเค‚เคฆเฅ€: เคšเฅ‚เค‚เค•เคฟ เคตเคน เคฌเฅ€เคฎเคพเคฐ เคฅเคพ, เคตเคน เคจเคนเฅ€เค‚ เค†เคฏเคพเฅค)
โŒ Because he ran fast, so he caught the bus.
โœ… Because he ran fast, he caught the bus.
(เคนเคฟเค‚เคฆเฅ€: เค•เฅเคฏเฅ‹เค‚เค•เคฟ เคตเคน เคคเฅ‡เคœเคผ เคฆเฅŒเคกเคผเคพ, เค‰เคธเคจเฅ‡ เคฌเคธ เคชเค•เคกเคผ เคฒเฅ€เฅค)

๐Ÿšจ Trap 4: The "Doubt" Dilemma

The verb "Doubt" acts like a chameleon. It changes its conjunction based on how sure you are.

  • In an Affirmative sentence (I doubt...), there is uncertainty. Therefore, use the choice words if / whether.
  • In a Negative or Interrogative sentence (I do not doubt...), there is 100% certainty. Therefore, use the definite word that.
Trap (Uncertain)
โŒ I doubt that he will come today.
Correct
โœ… I doubt if/whether he will come today.
(เคนเคฟเค‚เคฆเฅ€: เคฎเฅเคเฅ‡ เคธเค‚เคฆเฅ‡เคน เคนเฅˆ เค•เคฟ เค•เฅเคฏเคพ เคตเคน เค†เคœ เค†เคเค—เคพเฅค)
Trap (Certain)
โŒ I have no doubt if he will pass.
Correct
โœ… I have no doubt that he will pass.
(เคนเคฟเค‚เคฆเฅ€: เคฎเฅเคเฅ‡ เค•เฅ‹เคˆ เคธเค‚เคฆเฅ‡เคน เคจเคนเฅ€เค‚ เคนเฅˆ เค•เคฟ เคตเคน เคชเคพเคธ เคนเฅ‹ เคœเคพเคเค—เคพเฅค)

๐Ÿšจ Trap 5: As vs. Like

In spoken English, people mix these up constantly, but SSC tests the strict grammar rule:

โ€ข "As" is a Conjunction: It MUST be followed by a full clause (Subject + Verb).
โ€ข "Like" is a Preposition: It MUST be followed ONLY by an Object (Noun/Pronoun).

โŒ He ran like he was chased by a ghost.
โœ… He ran as he was chased by a ghost.
(เคนเคฟเค‚เคฆเฅ€: เคตเคน เคเคธเฅ‡ เคฆเฅŒเคกเคผเคพ เคœเฅˆเคธเฅ‡ เค•เฅ‹เคˆ เคญเฅ‚เคค เค‰เคธเค•เคพ เคชเฅ€เค›เคพ เค•เคฐ เคฐเคนเคพ เคนเฅ‹เฅค)
(Because 'he was chased' has a subject and verb, we must use 'as').
Preposition Example
โœ… He runs like a cheetah.
(เคนเคฟเค‚เคฆเฅ€: เคตเคน เคšเฅ€เคคเฅ‡ เค•เฅ€ เคคเคฐเคน เคฆเฅŒเคกเคผเคคเคพ เคนเฅˆเฅค)
('A cheetah' is just a noun, no verb. So 'like' is correct).

๐Ÿšจ Trap 6: Both... And (Not 'As well as')

The word "Both" signals that two items carry exactly equal weight. It is strictly married to "And". SSC examiners will try to pair it with "as well as" (which implies one item is less important). This is an absolute error.

โŒ Both Ram as well as Shyam are going.
โœ… Both Ram and Shyam are going.
(เคนเคฟเค‚เคฆเฅ€: เคฐเคพเคฎ เค”เคฐ เคถเฅเคฏเคพเคฎ เคฆเฅ‹เคจเฅ‹เค‚ เคœเคพ เคฐเคนเฅ‡ เคนเฅˆเค‚เฅค)

๐Ÿšจ Trap 7: As if / As though (Subjunctive Mood)

These conjunctions show an imaginary or fake reality (เคฎเคพเคจเฅ‹ เค•เคฟ). Because the situation is not real, English grammar breaks the normal tense rules to signal this "fake reality".

Rule: They must ALWAYS be followed by the past plural verb 'were', regardless of whether the subject is singular (I, he, she, it).

โŒ He orders me about as if he was my boss.
โœ… He orders me about as if he were my boss.
(เคนเคฟเค‚เคฆเฅ€: เคตเคน เคฎเฅเคเฅ‡ เคเคธเฅ‡ เค†เคฆเฅ‡เคถ เคฆเฅ‡เคคเคพ เคนเฅˆ เคฎเคพเคจเฅ‹ เคตเคน เคฎเฅ‡เคฐเคพ เคฌเฅ‰เคธ เคนเฅ‹เฅค)
(He is not actually the boss, so we use 'were' to show imagination).

๐Ÿšจ Trap 8: "Supposing If" Redundancy

The words "Supposing" and "If" both mean the exact same thing (creating a hypothetical condition). Using them together is like saying "If if". It is a major redundancy error.

โŒ Supposing if he fails, what will he do?
โœ… Supposing he fails, what will he do?
(เคนเคฟเค‚เคฆเฅ€: เคฎเคพเคจ เคฒเฅ€เคœเคฟเค เค•เคฟ เคตเคน เคซเฅ‡เคฒ เคนเฅ‹ เคœเคพเคคเคพ เคนเฅˆ, เคคเฅ‹ เคตเคน เค•เฅเคฏเคพ เค•เคฐเฅ‡เค—เคพ?)
OR: If he fails, what will he do?

๐Ÿšจ Trap 9: Such... as vs. Such... that

Such... as: Used to give examples or define a category (เคœเฅˆเคธเฅ‡ เค•เคฟ).
Such... that: Used to show an extreme Cause & Effect relationship (เค‡เคคเคจเคพ... เค•เคฟ).

โŒ He is such a fool as he cannot understand this.
โœ… He is such a fool that he cannot understand this.
(เคนเคฟเค‚เคฆเฅ€: เคตเคน เค‡เคคเคจเคพ เคฌเคกเคผเคพ เคฎเฅ‚เคฐเฅเค– เคนเฅˆ เค•เคฟ เคตเคน เคฏเคน เคจเคนเฅ€เค‚ เคธเคฎเค เคธเค•เคคเคพเฅค)
(Cause: He is a fool. Effect: He cannot understand. Use 'that').
Example Category
โœ… I do not like such boys as Ram.
(เคนเคฟเค‚เคฆเฅ€: เคฎเฅเคเฅ‡ เคฐเคพเคฎ เคœเฅˆเคธเฅ‡ เคฒเคกเคผเค•เฅ‡ เคชเคธเค‚เคฆ เคจเคนเฅ€เค‚ เคนเฅˆเค‚เฅค)
(Ram is an example of a category. Use 'as').

๐Ÿšจ Trap 10: As... as vs. So... as

As... as: Can be used in BOTH Positive and Negative sentences to show equality.
So... as: Can ONLY be used in strictly Negative sentences!

โŒ He is so good as Ram.
โœ… He is as good as Ram.
(เคนเคฟเค‚เคฆเฅ€: เคตเคน เคฐเคพเคฎ เคœเคฟเคคเคจเคพ เคนเฅ€ เค…เคšเฅเค›เคพ เคนเฅˆเฅค)
(This is a Positive sentence, it MUST use as...as).
Negative Sentences (Both Allowed)
โœ… He is not as good as Ram.
OR
โœ… He is not so good as Ram.
(เคนเคฟเค‚เคฆเฅ€: เคตเคน เคฐเคพเคฎ เคœเคฟเคคเคจเคพ เค…เคšเฅเค›เคพ เคจเคนเฅ€เค‚ เคนเฅˆเฅค)

๐Ÿšจ Trap 11: The "Same" Rule (That vs. As)

The same... that: Used when referring to the exact, identical item, and is followed by a verb clause.
The same... as: Used to show similarity (of the same kind).

โŒ This is the same book which I wanted.
โœ… This is the same book that I wanted.
(Referring to the exact book. 'which' is always wrong after 'the same').
โœ… My pen is the same as yours.
(Showing similarity).

๐Ÿšจ Trap 12: The "Seldom" Idioms

SSC tests two exact idioms for "rarely/never". Memorize them exactly as they are. You cannot mix them.

โœ… Correct: "Seldom or never" AND "Seldom if ever"

โŒ He seldom or ever tells a lie.
โœ… He seldom or never tells a lie.
OR: He seldom if ever tells a lie.

๐Ÿšจ Trap 13: Because vs. Because of

Because: is a Conjunction. It MUST be followed by a Subject + Verb.
Because of: is a Preposition. It MUST be followed by a Noun/Pronoun only.

โŒ He failed because of he was lazy.
โœ… He failed because he was lazy.
(Subject 'he' + Verb 'was').
โŒ He failed because his laziness.
โœ… He failed because of his laziness.
(Laziness is just a Noun).

Previous Year SSC Questions (Mega Bank)

Test your knowledge with these 25 high-frequency, actual Conjunction questions from recent CGL, CHSL, and CPO exams. Scroll down and click to reveal detailed explanations.

Q1. No sooner had he entered the room when the lights went out. (CGL 2022)
Error: when โž” than.
Rule: 'No sooner' strictly pairs with 'than' (not when or then).
Q2. Scarcely had the match started than it began to rain. (CPO 2021)
Error: than โž” when.
Rule: 'Hardly/Scarcely' strictly pairs with 'when' or 'before'.
Q3. Walk carefully lest you should not fall. (CHSL 2020)
Error: should not โž” should.
Rule: 'Lest' means 'so that... not'. It already contains a negative meaning, so adding 'not' is a double negative error.
Q4. Not only he is a writer but also an actor. (MTS 2022)
Error: Not only he is โž” He is not only.
Rule: Parallelism rule. 'But also' is followed by a noun (actor). Therefore, 'Not only' must also be placed directly before the noun (writer).
Q5. Although he worked hard, but he failed. (CGL 2021)
Error: but โž” yet / (comma).
Rule: 'Although/Though' pairs with 'yet' or a comma. Using 'but' is grammatically incorrect.
Q6. Since you are my friend, therefore I will help you. (CHSL 2019)
Error: therefore โž” (remove).
Rule: Redundancy error. Sentences starting with 'Since/As/Because' do not take 'so/therefore' in the second clause.
Q7. Both Ram as well as Shyam are coming. (CPO 2020)
Error: as well as โž” and.
Rule: The correlative pair is 'Both... and'. Using 'as well as' is a frequent SSC trap.
Q8. Unless you do not apologize, I will not forgive you. (CGL 2023)
Error: do not apologize โž” apologize.
Rule: 'Unless' is a negative condition. You cannot use 'not' inside the clause starting with 'Unless'.
Q9. Hardly I had stepped out when it started raining. (CGL Mains 2020)
Error: I had โž” had I.
Rule: Rule of Inversion! When a sentence STARTS with a negative adverb (Hardly, Scarcely, No sooner), the helping verb must come before the subject.
Q10. I doubt that he will come. (CPO 2022)
Error: that โž” if / whether.
Rule: In affirmative sentences, 'doubt' pairs with 'if/whether'. In negative/interrogative sentences (I do not doubt), it pairs with 'that'.
Q11. Make haste lest you will miss the bus. (CHSL 2021)
Error: will โž” should.
Rule: The conjunction 'lest' is strictly followed by the modal 'should'.
Q12. Between 9 AM to 10 AM, the shop is closed. (MTS 2019)
Error: to โž” and.
Rule: The preposition 'Between' always pairs with the conjunction 'and'. ('From' pairs with 'to').
Q13. He has no other choice but to accept the offer. (CGL 2019)
Error: but โž” than.
Rule: 'Other' and 'Rather' are comparative words that pair with 'than'. 'Nothing else' pairs with 'but'.
Q14. The reason why he failed is because he didn't study. (CGL 2022)
Error: because โž” that.
Rule: The phrase "The reason why" already gives the cause. Using "because" is redundant. It must be paired with "that".
Q15. Not only the principal but also the teachers was present. (CPO 2021)
Error: was โž” were.
Rule: In "Not only... but also" structures, the verb agrees with the subject nearest to it (teachers = plural = were).
Q16. Seldom or ever have I seen such a beautiful painting. (CHSL 2023)
Error: ever โž” never.
Rule: The correct idioms are "Seldom or never" OR "Seldom if ever".
Q17. Either he will stay here or go to Delhi. (MTS 2021)
Error: Either he will stay โž” He will either stay.
Rule: Parallelism. "Or" is followed by a verb (go). "Either" must also be followed by a verb (stay).
Q18. This is the same book which I wanted. (CGL 2020)
Error: which โž” that.
Rule: The phrase "the same" is paired with "that" (when referring to the exact same item and followed by a full verb clause) or "as" (for similar kind). Never 'which'.
Q19. He asked me that why I was late. (CPO 2019)
Error: that why โž” why.
Rule: In indirect speech, interrogative words (Why, Where, How) act as conjunctions themselves. You cannot place 'that' before them.
Q20. Wait here unless the train arrives. (CHSL 2020)
Error: unless โž” until.
Rule: Waiting is related to Time. "Until" is used for Time, "Unless" is used for Action/Condition.
Q21. As soon as he arrived, then he started working. (CGL 2021)
Error: then โž” (comma).
Rule: "As soon as" is not followed by 'than' or 'then'. It only takes a comma to separate the clauses.
Q22. Neither he is tall nor strong. (MTS 2022)
Error: Neither he is โž” He is neither.
Rule: Parallelism. "Nor" is followed by an adjective (strong). "Neither" must be followed by an adjective (tall).
Q23. I cannot say if he will pass or not. (CPO 2021)
Error: if โž” whether.
Rule: When the word "or" is present in the sentence offering an alternative, you must use "whether... or", not "if... or".
Q24. No sooner the minister finished his speech than the crowd applauded. (CGL 2019)
Error: the minister finished โž” did the minister finish (or: had the minister finished).
Rule: Rule of Inversion. "No sooner" must be immediately followed by a helping verb (did/had) before the subject.
Q25. Supposing if he refuses to help you, what will you do? (CHSL 2022)
Error: Supposing if โž” Supposing (or If).
Rule: Redundancy error. Both "Supposing" and "If" convey a condition. You cannot use them together.
