Let’s compile all grammatical rules for SVO into one complete guide.
This will cover formation, variations, transformations, and grammar points connected with SVO.

Complete SVO Grammar Rules

1. Basic SVO Rule

Word order in English:
Subject → Verb → Object

✅ Examples:

I eat apples.
She plays the piano.
They like chocolate.

2. Subject Rules (S)

The subject is the doer of the action.
Can be:
- Noun: The boy runs.
- Pronoun: He runs.
- Gerund: Swimming is fun.
- Clause: What you said is true.

⚠️ English requires a subject (no subject-dropping like in Spanish or Hindi).

❌ Wrong: Is raining.
✅ Correct: It is raining.

3. Verb Rules (V)

Verb must agree with subject in number & person:
- He eats (singular).
- They eat (plural).
Verb forms depend on tense, aspect, and mood.
- Simple: She reads books.
- Progressive: She is reading books.
- Perfect: She has read books.

4. Object Rules (O)

Object is the receiver of the action.
Two main types:
- Direct Object (DO): receives the action directly.
  - She reads a book.
- Indirect Object (IO): receives the action indirectly.
  - She gave me a book.
Object answers:
- What? → She bought a car.
- Whom? → He helped his friend.

5. Negatives in SVO

Negatives keep SVO order.
Use auxiliary verb + not.

✅ Examples:

I do not like tea.
She is not reading a book.
They will not play football.

6. Questions in SVO

In questions, auxiliaries come before the Subject.
SVO is still inside the answer.

✅ Examples:

Do you like apples? → Yes, I (S) like (V) apples (O).
What did she eat? → She (S) ate (V) rice (O).

7. Passive Voice (Reversed SVO)

Object becomes the subject.
Formula: Object + be + past participle + (by + subject).

✅ Examples:

Active: John (S) ate (V) the cake (O).
Passive: The cake (S) was eaten (V) by John (O).

8. Variations of SVO

SV (no object)
- Birds fly.
- He sleeps.
SVOO (double object)
- She gave me (IO) a book (DO).
SVOC (object + complement)
- They elected him president.
- She painted the wall blue.

9. Adverbs in SVO

Adverbs may appear before or after, but do not change SVO.

✅ Examples:

She quickly (Adv) finished (V) the project (O).
They watched (V) the movie (O) yesterday (Adv).

10. Complex & Compound Sentences

Even in longer sentences, main clause follows SVO.

✅ Examples:

When the rain stopped, the children (S) played (V) football (O).
She said (S) that she (S) likes (V) ice cream (O).

11. Commands & Imperatives

Subject “you” is implied.

✅ Examples:

(You) Close the door.
(You) Write a letter.

12. Exceptions & Flexibility

Poetry/literature may bend SVO: Happy is the man who sings.
Questions flip order: Are you ready?
Exclamations may omit objects: What a day!

13. Agreement & Consistency

Subject and verb must always agree.
Object must logically fit the verb.

✅ Correct: The teacher explains the lesson.
❌ Wrong: The lesson explains the teacher. (changes meaning!)

14. Transformations

Active ↔ Passive (swap S & O)
Affirmative ↔ Negative (add not)
Statement ↔ Question (invert subject/auxiliary)

✅ Final Summary: SVO Grammar Rules

Default order: S → V → O
Subject is required in English
Verb agrees with subject (number/person)
Object = receiver (direct/indirect)
Negatives keep SVO order
Questions invert subject & auxiliary
Passive voice swaps subject and object
Variations: SV, SVOO, SVOC
Adverbs don’t change SVO
Complex/compound sentences still follow SVO in main clause
Commands imply subject "you"
Exceptions in poetry/literature
Maintain subject–verb–object agreement
Sentences can transform (active ↔ passive, positive ↔ negative, statement ↔ question)

Let’s make a full chart of all SVO rules with explanations and examples so you can use it as a quick-reference grammar sheet.

Rule	Explanation	Example (Correct)	Example (Wrong)

4. Object Rule	Object = receiver of action → answers what? / whom?	She reads a book. (What?)	She reads. (incomplete if object expected)
5. Negatives	Use auxiliary + not. Keep SVO order.	I do not like tea.	Not I like tea.
6. Questions	Auxiliary/verb comes before subject.	Do you like apples?	You like apples? (incorrect in formal English)

8. SV (No Object)	Some verbs don’t take objects.	Birds fly. / He sleeps.	He sleeps bed. (needs prep → on the bed)

14. Imperatives	Subject “you” is implied.	(You) Close the door.	Close door you.
15. Transformations	Change forms but SVO base remains.	Statement → She eats rice. Negative → She does not eat rice. Question → Does she eat rice? Passive → Rice is eaten by her.	Eat rice she not.
