Sentence Structure — The Skeleton of English

🎯 Why This Chapter Can Change Your Score

Every single question in the English section of SSC GD, SSC MTS, RRB Group D and State Police exams — whether it is Error Spotting, Fill in the Blanks, Sentence Improvement or Rearrangement — is secretly a Sentence Structure question. If you can see the skeleton of a sentence (Subject + Verb + Object), you can catch errors that other candidates never even notice. Toppers don't "feel" the answer; they see the structure. This chapter teaches you exactly that.

Learning Objectives

By the end of this chapter, you will be able to:

1. Identify the Subject, Verb and Object in any sentence within seconds.
2. Recognise the five basic sentence patterns of English.
3. Classify sentences as Simple, Compound, Complex and Compound-Complex.
4. Apply the 12 Golden Rules of sentence structure to error-spotting questions.
5. Avoid the typical mistakes Hindi speakers make in English word order.

1. What Is a Sentence?

A sentence is a group of words that expresses a complete thought and contains at least one Subject (who/what the sentence is about) and one Verb (what the subject does or is).

• ✅ *The boy runs.* (Subject: The boy | Verb: runs — complete thought)
• ❌ *Running in the park.* (No subject — incomplete thought; this is a fragment)

The two compulsory parts:

🧠 Active Recall: Close the book. What two things must every complete sentence have? Is "Under the table" a sentence? Why not?

2. The Core Trio: Subject – Verb – Object (SVO)

English follows a fixed word order: Subject → Verb → Object.

• *Ravi (S) eats (V) mangoes (O).*
• *The police (S) caught (V) the thief (O).*

How to find them in an exam:

1. Find the verb first (the action/state word).
2. Ask "who/what + verb?" → that is the subject.
3. Ask "verb + whom/what?" → that is the object.

Example: *The farmer grows wheat.*

• Verb = grows → Who grows? = the farmer (Subject) → Grows what? = wheat (Object).

⚠️ Not every sentence has an object. Verbs like *sleep, run, arrive, die* (intransitive verbs) take no object: *The baby sleeps.*

🧠 Active Recall: In "The students solved the puzzle quickly," find the verb, subject and object. Does "quickly" answer "what?" — or something else?

3. The Five Basic Sentence Patterns

Every English sentence, however long, is built on one of these five frames:

Exam tip: In Pattern 3, the verb is a linking verb (is, seem, become, look, taste, feel). After a linking verb we use an adjective, not an adverb: *The food smells good* ✅ (not "well").

4. Phrase, Clause, Sentence — Know the Difference

• Phrase = a group of words with no subject-verb pair: *in the morning, running fast, a tall man.*
• Clause = a group of words with a subject-verb pair:
• Independent clause — stands alone: *She sings well.*
• Dependent clause — cannot stand alone; begins with words like *because, when, if, although, which*: *because she was tired…* (incomplete feeling!)

🧠 Active Recall: "Although he worked hard" — phrase, dependent clause or independent clause? What word makes it dependent?

5. The Four Types of Sentences (by Structure)

🔑 Mnemonic — "FANBOYS": the seven coordinating conjunctions that join independent clauses in a compound sentence — For, And, Nor, But, Or, Yet, So.

Joining words for dependent clauses (subordinating conjunctions): because, since, although, though, when, while, if, unless, until, after, before, as, that, which, who.

🧠 Active Recall: "He was ill, so he stayed at home." — simple, compound or complex? Which FANBOYS word joins the clauses?

6. Sentences by Purpose

⚠️ Examiner's Trap — The 12 Golden Rules of Sentence Structure

1. Every sentence needs a finite verb. ❌ *He being late.* (a fragment — "being" is not a finite verb) → ✅ *He was late.*
2. A dependent clause alone is a fragment. ❌ *Because he was ill.* (standing alone) → ✅ *Because he was ill, he stayed at home.*
3. Two independent clauses joined by only a comma = comma splice. ❌ *He came, he sat down.* → ✅ *He came, and he sat down.* / *He came; he sat down.*
4. After a linking verb, use an adjective. *She looks beautiful* (not "beautifully").
5. The subject is never inside a prepositional phrase. *The quality of the mangoes was good* (subject = quality, not mangoes).
6. Inversion after negative openers: *Never have I seen such a sight.* / *Hardly had he arrived when…*
7. Embedded questions use statement order: *I don't know where he is.* (not "where is he").
8. "There" is not the subject. *There are three books on the table* (subject = books).
9. Each/Every/One of + plural noun takes a singular verb. *Each of the boys has a pen.*
10. Correlative pairs must be parallel: *Neither Ram nor Shyam*, *not only…but also*, *either…or*.
11. A sentence must not shift tense without reason. ❌ *He entered the room and sits down.* → ✅ *He entered the room and sat down.*
12. Imperative sentences have a hidden "you". Tag: *Open the window, will you?*

Common traps in exams: (a) an intervening phrase hiding the real subject (Rule 5), (b) a fragment dressed up as a full sentence (Rules 1–2), (c) adjective–adverb swap after linking verbs (Rule 4).

याद रखें: हिंदी में क्रिया अंत में आती है (राम आम खाता है), English में क्रिया बीच में (Ram eats mangoes)। Word order बदलना ही आधी grammar है।

🔁 Review After 2 Days

Come back after 48 hours and do this without looking:

1. Write the five sentence patterns from memory.
2. Say the FANBOYS mnemonic aloud and name all seven conjunctions.
3. Correct these: (a) *The price of onions are rising.* (b) *Because he was late.* (c) *I don't know where is he.*
4. Re-read the 12 Golden Rules and tick the ones you remembered without help.

(Answers: (a) *is* rising — subject is "price"; (b) fragment — add a main clause; (c) *where he is*.)
