In English grammar, sentences are broadly categorized based on two main criteria: function (what they do) and structure (how they are built).
I. Sentence Types Based on Function
This classification describes the purpose of the sentence.
* Declarative Sentence
Example:
* The sun rises in the east.
* I believe honesty is the best policy.
* Interrogative Sentence
Example:
* Are you coming to the party tonight?
* What is your favorite color?
* Imperative Sentence
Example:
* Close the door.
* Please pass the salt.
* Always look both ways before crossing the street.
* Exclamatory Sentence
Example:
* What a beautiful day!
* I can't believe we won!
II. Sentence Types Based on Structure
This classification describes how clauses are combined within a sentence. A clause is a group of words that contains a subject and a verb. An independent clause can stand alone as a complete thought, while a dependent clause cannot.
* Simple Sentence
Example:
* The dog barked loudly.
* Mary and John went to the store.
* She sings and dances beautifully.
* Compound Sentence
Example:
* I wanted to go to the concert, but I couldn't get ticket.
* She studied diligently; consequently, she passed the exam with flying colors.
* He loves to read, and he enjoys writing short stories.
* Complex Sentence
Example:
* Although it was raining, we decided to go for a walk.
* I will call you when I arrive.
* The man who lives next door is a doctor.
