📘 What are Simple, Compound, and Complex Sentences?

Simple Sentence

A simple sentence is a short sentence consisting of a subject and a predicate. In other words, it has one main clause (independent clause) and expresses a complete thought. It can also be a combination of a phrase and a clause .

Examples:

  • I was playing football. 

  • She came here to see me. 

  • The sun looks amazing today. 

Compound Sentence

A compound sentence has more than one main clause (independent clauses). The clauses are of equal importance and can convey a coherent thought independently. They are combined using a coordinating conjunction (FANBOYS: For, And, Nor, But, Or, Yet, So) or a conjunctive adverb .

Examples:

  • I can sing, and she can draw. 

  • He finished his homework and went to play. 

  • She is innocent, so she has appealed to the court. 

Complex Sentence

A complex sentence has one main clause and one or more subordinate (dependent) clauses. The dependent clause cannot exist independently as it does not convey a complete meaning. They are combined using a subordinating conjunction or a correlative conjunction .

Examples:

  • After the cyclone hit the country, roads and houses were damaged. 

  • He worked hard that he might pass the examination. 

  • I remember the day that we met very well.
