Conjunction — The Glue of English Sentences
🔗 Why This Chapter Matters
Imagine two railway coaches without a coupling — each coach is fine on its own, but the train cannot move. Sentences are the same. *"He worked hard. He failed."* is two lonely coaches. *"He worked hard, yet he failed."* is a train — and that tiny word yet is exactly what SSC CHSL, RRB NTPC and Bank exams test, again and again. Master conjunctions and you unlock error-spotting, sentence improvement, fill-in-the-blanks and cloze tests — four question types from one chapter.
🎯 Learning Objectives
By the end of this chapter you will be able to:
- Define a conjunction and identify it in any sentence.
- Distinguish the three types: Coordinating, Subordinating and Correlative.
- Apply the 12 Golden Rules (pairs like *either…or*, *no sooner…than*, *hardly…when*).
- Spot the classic traps examiners set around *until/unless*, *since/because*, and *though/but*.
- Solve a conjunction question in under 15 seconds using pair-matching.
1. What Is a Conjunction?
A conjunction is a word that joins words, phrases or clauses.
- Words: *tea and coffee*
- Phrases: *in the morning or in the evening*
- Clauses: *She sang while he played the flute.*
Think of a conjunction as a bridge. It never carries meaning alone; its whole job is to connect two banks of meaning and show the *relationship* between them — addition, contrast, choice, reason, time or condition.
🧠 Active Recall: Without looking back — what three things can a conjunction join? Give one example of each.
2. Type 1 — Coordinating Conjunctions (The FANBOYS)
Coordinating conjunctions join equal elements — two words, two phrases, or two independent clauses. Remember them with the mnemonic:
> FANBOYS = For, And, Nor, But, Or, Yet, So
| Conjunction | Relationship | Example |
|---|---|---|
| For | reason | He stayed home, for he was ill. |
| And | addition | Ram and Shyam came. |
| Nor | negative addition | He neither called nor wrote. |
| But | contrast | She is poor but honest. |
| Or | choice | Run fast, or you will miss the train. |
| Yet | contrast (surprise) | He is rich, yet unhappy. |
| So | result | It rained, so the match was cancelled. |
⚠️ *For* as a conjunction is formal and means "because" — do not confuse it with the preposition *for* ("a gift for you").
🧠 Active Recall: Recite FANBOYS. Which two FANBOYS show contrast? Which one shows result?
3. Type 2 — Subordinating Conjunctions (The Dependent-Makers)
A subordinating conjunction joins a dependent (subordinate) clause to an independent (main) clause. The dependent clause cannot stand alone.
- *Because it rained*, the match was cancelled. ✅
- *Because it rained.* ❌ (incomplete — leaves the listener waiting)
Group them by job:
| Job | Conjunctions |
|---|---|
| Time | when, while, before, after, until, since, as soon as, no sooner…than, hardly…when |
| Reason | because, since, as |
| Condition | if, unless, provided that, in case |
| Contrast/Concession | though, although, even though, whereas, while |
| Purpose | so that, in order that, lest |
| Comparison | than, as…as |
Key behaviour: if the subordinate clause comes first, use a comma: *"Although he is rich, he is humble."* If it comes second, usually no comma: *"He is humble although he is rich."*
🧠 Active Recall: Turn this into one sentence using *unless*: "Work hard. You will fail otherwise." (Answer: *Unless you work hard, you will fail.*)
4. Type 3 — Correlative Conjunctions (The Fixed Pairs)
These work in pairs, and exams attack the pairing mercilessly. Memorise the pairs as one unit:
| Pair | Example |
|---|---|
| either … or | Either come in, or go out. |
| neither … nor | Neither Ram nor Shyam came. |
| not only … but also | She is not only wise but also kind. |
| both … and | Both his father and his mother are doctors. |
| whether … or | I don't know whether he will come or not. |
| no sooner … than | No sooner did she arrive than it rained. |
| hardly/scarcely … when | Hardly had he slept when the phone rang. |
| such … that | It was such a hot day that we stayed inside. |
| the more … the more | The more you read, the more you learn. |
Parallelism rule: whatever follows the first half of the pair must grammatically match what follows the second half.
- ❌ *He not only plays cricket but also football.*
- ✅ *He plays not only cricket but also football.* (both halves followed by a noun)
🧠 Active Recall: Fill the blanks: *No sooner ___ the bell ring ___ the students rushed out.* (did … than)
5. The 12 Golden Rules of Conjunctions ⭐
- Either…or / Neither…nor — never mix them (*either…nor* ❌).
- No sooner takes *than*; hardly/scarcely take *when* — never swap.
- Although/Though never pairs with but — use *yet* or nothing: *Though he is ill, (yet) he works.* ❌ *Though he is ill, but he works.*
- Because/Since/As never pairs with therefore/so: *Because he was ill, he stayed home.* ❌ *Because he was ill, so he stayed home.*
- Unless = "if…not" — it is already negative, so never add *not*: ❌ *Unless you do not work…* ✅ *Unless you work…*
- Until refers to time; unless refers to condition: *Wait until I return.* / *Don't go unless I call you.*
- Since (reason) vs because: *since* is fine at the start of a sentence; *because* answers "why?" directly.
- Lest is followed by should (or the bare verb), never by *not*: *Walk fast lest you should miss the train.*
- Both…and cannot take a negative verb: ❌ *Both Ram and Shyam did not go.* ✅ *Neither Ram nor Shyam went.*
- As well as / along with / together with are not true conjunctions — the verb agrees with the first subject: *Ram, as well as his brothers, is going.*
- Rather than / sooner than are followed by the bare infinitive: *I would die rather than beg.*
- The reason…is that, not *the reason…is because*: ✅ *The reason he failed is that he didn't study.*
⚠️ Examiner's Trap Box
Trap 1 — The Double Conjunction: Examiners love *"Though he is poor, but he is honest"* and *"Because he was late, so he missed the bus."* Your eye must scream: two conjunctions for one join = wrong. Delete one.
Trap 2 — The Broken Pair: *"No sooner had he entered when the lights went off."* Sounds smooth, reads wrong — *no sooner* demands than. Say the pair aloud as one word: *nosooner…than*, *hardly…when*.
Trap 3 — Unless + Not: *"Unless you do not apologise, I will not forgive you."* Double negative = the sentence now means the opposite of what was intended. Unless already contains the "not".
🔁 Linguistic Bridge — Hindi से English
| हिंदी में हम सोचते हैं | गलत English | सही English |
|---|---|---|
| "यद्यपि वह गरीब है, परंतु वह ईमानदार है" (दोनों शब्द स्वाभाविक लगते हैं) | Though he is poor, but he is honest. | Though he is poor, he is honest. |
| "क्योंकि वह बीमार था, इसलिए वह नहीं आया" | Because he was ill, so he didn't come. | Because he was ill, he didn't come. |
| "जब तक तुम मेहनत नहीं करोगे…" (unless को *not* चाहिए लगता है) | Unless you do not work hard… | Unless you work hard… |
| "न तो राम और न श्याम" | Neither Ram or Shyam | Neither Ram nor Shyam |
Hindi happily uses double connectors (यद्यपि…परंतु, क्योंकि…इसलिए); English allows only one connector per join. When in doubt, count your connectors.
6. Mnemonic to Lock the Pairs 🔑
> "No Sooner THAN, Hardly WHEN — E-N pairs, E-O friends."
> *No sooner* marries *than*; *hardly/scarcely* marry *when*; Neither marries Nor (N-N); Either marries Or (E-O).
7. Summary Table
| Type | Joins | Examples | Exam Hotspot |
|---|---|---|---|
| Coordinating | Equals | FANBOYS | *but/yet* contrast; *so* result |
| Subordinating | Dependent → main | because, although, unless, until, lest | double-conjunction errors |
| Correlative | Fixed pairs | either…or, no sooner…than | broken-pair errors, parallelism |
📌 Review after 2 days
Come back after 48 hours and do this without notes: (1) write FANBOYS from memory, (2) write all 9 correlative pairs, (3) correct this sentence — *"No sooner did he reach when it rained, but he was already wet."* If you can fix both errors in 15 seconds, the chapter is yours.
