📌 I. Types of Sentences by Purpose (Function)
English sentences are used for different reasons: making statements, asking questions, giving commands, or expressing emotions. Based on this, there are four main types of sentences:
---
1. Declarative Sentence (Assertive Sentence)
Purpose: To make a statement, express a fact, or share an opinion.
Punctuation: Ends with a full stop (period).
✅ Examples:
The sun rises in the east.
She is preparing for her CSS exam.
I believe honesty is the best policy.
📝 Note: Declarative sentences are the most common type in writing and speech.
---
2. Interrogative Sentence
Purpose: To ask a question or seek information.
Punctuation: Ends with a question mark (?).
✅ Examples:
What is your name?
Do you speak English?
Have you ever visited Karachi?
🧠 Types of Questions:
Yes/No questions: Are you tired?
Wh- questions: Where are you going?
Choice questions: Would you like tea or coffee?
---
3. Imperative Sentence
Purpose: To give a command, instruction, request, or advice.
Punctuation: Usually ends with a full stop, sometimes an exclamation mark.
✅ Examples:
Close the door.
Please be quiet.
Don’t waste your time!
👤 Note: The subject "you" is understood but not stated.
---
4. Exclamatory Sentence
Purpose: To express strong emotions like surprise, excitement, or anger.
Punctuation: Ends with an exclamation mark (!)
✅ Examples:
What a beautiful view!
I can’t believe this!
Oh no! I forgot my keys!
🧠 Tip: Use exclamatory sentences sparingly in formal writing.

📌 II. Types of Sentences by Structure (Grammatical Form)
While sentence purpose tells why a sentence is used, sentence structure tells how it is formed. Based on structure, English sentences are categorized into four types:
---
1. Simple Sentence
A sentence with only one independent clause (a complete thought).
✅ Examples:
He plays football.
The moon looks beautiful tonight.
She studies hard for exams.
🔍 Structure: [Subject + Verb + Object]
> One idea, one clause, no dependency.
---
2. Compound Sentence
A sentence with two or more independent clauses joined by a coordinating conjunction (FANBOYS: for, and, nor, but, or, yet, so).
✅ Examples:
I was tired, but I finished my work.
She likes tea, and he prefers coffee.
🔧 Structure: [Independent Clause] + , + [Coordinating Conjunction] + [Independent Clause]
🧠 Tip: Each part must make sense on its own.
---
3. Complex Sentence
A sentence with one independent clause and at least one dependent (subordinate) clause.
✅ Examples:
Although it was raining, we went outside.
She left because she was upset.
🔧 Structure:
Subordinate Clause + , + Main Clause
Main Clause + Subordinate Clause
Subordinating Conjunctions: because, although, since, when, while, if, etc.
---
4. Compound-Complex Sentence
A sentence with two or more independent clauses and at least one dependent clause.
✅ Examples:
Although he was sick, he went to school, and he completed the exam.
I finished my homework, but I forgot to submit it because I was in a hurry.
🧠 Key Rule: Must have at least 3 clauses – two independent + one dependent.
