Conjunction — The Glue of English Sentences
🔗 Why This Chapter Can Change Your Score
Imagine two brilliant ideas standing in a room, unable to talk to each other. That is a sentence without a conjunction. In SSC CGL, IBPS PO, and State PCS prelims, conjunctions hide inside error-spotting, sentence improvement, fill-in-the-blanks, and cloze tests — and examiners love them because a single wrong pair ("No sooner than" vs "No sooner when") separates the selected from the rejected. Master this one chapter and you unlock marks across at least four question types.
🎯 Learning Objectives
By the end of this chapter you will be able to:
- Identify and correctly use all three types of conjunctions — Coordinating, Subordinating, and Correlative.
- Spot the classic paired-conjunction traps (either…or, neither…nor, not only…but also, no sooner…than, hardly/scarcely…when).
- Apply subject–verb agreement rules with correlative conjunctions (proximity rule).
- Eliminate "sound-right" wrong options in error-spotting questions within seconds.
- Distinguish conjunctions from prepositions and adverbs that look similar (e.g., *since, until, for*).
1. What Is a Conjunction?
A conjunction is a word that joins words, phrases, or clauses. It does not add meaning of its own; it shows the relationship between the parts it joins.
- Ram and Shyam are friends. *(joins two words)*
- She is poor but honest. *(joins two qualities — contrast)*
- I waited because the train was late. *(joins two clauses — reason)*
Think of a conjunction as a railway coupling: coaches (clauses) are useless separately on a journey; the coupling makes them one train.
🧠 Active Recall: Without looking back — (a) What three things can a conjunction join? (b) In "She is poor but honest," what relationship does *but* show?
2. Type 1 — Coordinating Conjunctions (FANBOYS)
Coordinating conjunctions join equals — word with word, phrase with phrase, independent clause with independent clause. There are exactly seven, remembered by the mnemonic FANBOYS:
| Letter | Conjunction | Relationship | Example |
|---|---|---|---|
| F | for | reason | He stayed, for he was tired. |
| A | and | addition | Tea and coffee are served. |
| N | nor | negative addition | He neither called, nor wrote. |
| B | but | contrast | Rich but unhappy. |
| O | or | choice | Tea or coffee? |
| Y | yet | contrast (surprise) | Old, yet energetic. |
| S | so | result | It rained, so we stayed home. |
Key exam point: When two independent clauses are joined by a coordinating conjunction, a comma usually comes before it: *"The bell rang, and the students left."*
🧠 Active Recall: Recite FANBOYS. Which FANBOYS conjunction shows (a) result, (b) reason, (c) surprising contrast?
3. Type 2 — Subordinating Conjunctions
A subordinating conjunction joins a dependent (subordinate) clause to an independent (main) clause. The dependent clause cannot stand alone.
Common subordinating conjunctions, grouped by meaning:
| Relationship | Conjunctions |
|---|---|
| Time | when, while, after, before, until, since, as soon as, no sooner…than, hardly…when |
| Reason | because, since, as, now that |
| Condition | if, unless, provided (that), in case, as long as |
| Contrast/Concession | although, though, even though, whereas, while |
| Purpose | so that, in order that, lest |
| Comparison | than, as…as |
Golden structural rule: If the subordinate clause comes first, use a comma after it: *"Although he is rich, he is humble."* If it comes second, no comma: *"He is humble although he is rich."*
The "because–so" trap: Hindi logic allows "क्योंकि…इसलिए" together, but English never uses *because* and *so* (or *although* and *but*) in the same sentence:
- ❌ Because he was ill, so he did not come.
- ✅ Because he was ill, he did not come. / He was ill, so he did not come.
- ❌ Although he is rich, but he is not happy.
- ✅ Although he is rich, he is not happy.
🧠 Active Recall: Why is "Although… but" wrong in English? Write one correct sentence using *unless*.
4. Type 3 — Correlative Conjunctions (The Paired Twins)
These work in pairs — and examiners attack the pairing:
| Pair | Usage | Example |
|---|---|---|
| either…or | choice | Either you work or you fail. |
| neither…nor | negative choice | Neither Ram nor Shyam came. |
| not only…but also | addition (emphasis) | She is not only wise but also kind. |
| both…and | addition | Both Delhi and Agra were visited. |
| whether…or | alternatives | Whether he comes or stays, I shall go. |
| no sooner…than | immediate sequence | No sooner did she arrive than it rained. |
| hardly/scarcely…when | immediate sequence | Hardly had he slept when the phone rang. |
| rather…than | preference | I would rather die than beg. |
| such…as / such…that | example / result | Such was his speed that none could catch him. |
The Proximity Rule (verb agreement): With *either…or* and *neither…nor*, the verb agrees with the subject nearer to it:
- Neither the teacher nor the students were present.
- Neither the students nor the teacher was present.
The Parallelism Rule: Both halves of a correlative pair must join the same grammatical structure:
- ❌ He not only plays cricket but also football. *(plays only cricket? ambiguous)*
- ✅ He plays not only cricket but also football.
🧠 Active Recall: (a) Which word pairs with *no sooner* — *when* or *than*? (b) Correct this: "Neither he nor his friends was there."
5. Conjunction vs Preposition vs Adverb — The Look-Alikes
Some words change job depending on use — a favourite advanced-level trap:
| Word | As Conjunction | As Preposition |
|---|---|---|
| since | Since he left, I am alone. *(+ clause)* | since Monday *(+ noun)* |
| until | Wait until I return. *(+ clause)* | until Friday *(+ noun)* |
| for | He stayed, for he was ill. *(+ clause)* | for you *(+ noun)* |
| after | After he came, we ate. *(+ clause)* | after lunch *(+ noun)* |
Test: If the word is followed by a subject + verb, it is a conjunction; if followed by a noun/pronoun only, it is a preposition.
🧠 Mnemonic — "FANBOYS on the BUS"
- FANBOYS = the 7 coordinating conjunctions (For, And, Nor, But, Or, Yet, So).
- BUS = the three big subordinating families: Because (reason), Unless (condition), Since/So that (time & purpose).
- For correlative traps, remember: "No sooner THAN, Hardly WHEN" — *sooner* has a T, so it takes Than; *hardly* has no T, so it takes when.
⚠️ Examiner's Trap Box
Trap 1 — The Wrong Partner: "No sooner had he entered when the bell rang." ❌ The correct partner is than. Examiners swap *than/when* and *nor/or* constantly.
Trap 2 — Double Conjunction: "Because he was late, so he missed the train." ❌ One conjunction per relationship. Delete *because* or *so*.
Trap 3 — Broken Parallelism: "He came not only to see me but also for meeting my father." ❌ Structures must match: *"…not only to see me but also to meet my father."*
🔁 Linguistic Bridge — Hindi सोच, English बोल
| Hindi-speaker's common error | Why it happens | Correct English |
|---|---|---|
| "Because I was tired, so I slept early." | Hindi: क्योंकि…इसलिए दोनों साथ | Because I was tired, I slept early. |
| "Although he worked hard, but he failed." | Hindi: यद्यपि…फिर भी | Although he worked hard, he failed. |
| "Neither he came nor he called not." | Hindi double negative: न…न | Neither did he come nor did he call. |
| "Unless you do not work hard, you will fail." | Hindi: जब तक नहीं | Unless you work hard, you will fail. *(unless already = if…not)* |
| "He as well as I are going." | Hindi treats both as subject | He as well as I is going. *(the verb agrees with the first subject, "He"; "as well as I" is only an addition)* |
📋 Summary Table
| Type | Members | Joins | Top Exam Trap |
|---|---|---|---|
| Coordinating | FANBOYS (7) | Equals | Comma before it between two clauses |
| Subordinating | because, although, if, unless, until, since… | Dependent + independent clause | Never pair because+so / although+but |
| Correlative | either…or, neither…nor, no sooner…than, hardly…when | Balanced pairs | Wrong partner word; proximity verb rule; parallelism |
