Definition of Sentence, Types of sentences

What is a Sentence?

A sentence is a group of words that expresses a complete thought. It must have a subject and a verb and begin with a capital letter and end with a punctuation mark.

Examples:

  • She is reading a book.
  • They went to the market.

Types of Sentences (by structure):

1.     Simple Sentence

A simple sentence has one independent clause. It expresses one complete idea and contains a subject and a verb.

Structure: Subject + Verb (+ Object)

Examples:

    • He plays football.
    • The sun rises in the east.

2.     Compound Sentence

A compound sentence contains two or more independent clauses joined by a coordinating conjunction (for, and, nor, but, or, yet, so).

Structure: Independent Clause + Coordinating Conjunction + Independent Clause

Examples:

    • I wanted to go for a walk, but it was raining.
    • She cooked dinner, and he washed the dishes.

3.     Complex Sentence

A complex sentence has one independent clause and one or more dependent (subordinate) clauses joined by a subordinating conjunction (because, although, since, if, etc.).

Structure: Independent Clause + Subordinating Conjunction + Dependent Clause

Examples:

    • I stayed home because I was sick.
    • Although he is rich, he is not happy.

 

Definition of a Simple Sentence

A simple sentence is a sentence that contains only one independent clause. It expresses a complete thought with a subject and a verb.

It does not contain any dependent clause or subordinate clause.


Structure of a Simple Sentence

Structure:
Subject + Verb (+ Object/Complement/Modifier)

It can be:

  • Short: "She runs quickly."
  • Long: "My friend from school who lives nearby runs every morning in the park."

Even if the sentence is long and has additional phrases, it remains a simple sentence as long as there is only one independent clause.

  • A – and
  • N – nor
  • B – but
  • O – or
