Need 8+ Simple, Compound-Complex, and Complex and Compound Sentences (Examples)?

Speech-language pathologists and other educators know how important it is to teach complex and compound sentences. Research has indicated how important comprehension of complex sentences is for reading comprehension. In addition to enhancing comprehension, knowing how to use compound and complex sentence structures can increase overall expressive language abilities, as well as written expression. This blog post includes complex and compound sentence examples. In addition, it explains the types of clauses, provides definitions for dependent and independent clauses, and recommends activities and goals for grammar and sentence structure. 

This blog post contains compound and complex sentences examples for speech therapy and special education.

The Types of Clauses

Before diving into the different structures, it can be useful to define the two main types of clauses.

Clauses are groups of words. They contain both a subject and a verb.

Main clauses are also known as independent clauses.

Subordinate clauses are also known as dependent clauses.

What Is a Dependent Clause? 

dependent clause is a group of words that contain a subject and a verb. However, a dependent clause is not a complete thought and these groups of words cannot stand alone. 

Dependent clauses typically start with a subordinating conjunction. A dependent clause is also known as a subordinate clause. 

Dependent clauses are linked to the independent clause using either a subordinating conjunction or a relative pronoun (which, that, who, whom). 

Here are a few examples of dependent clauses: 

  • Because she is talking
  • Although he was hungry
  • When the dog barks

Because a dependent clause can’t stand alone, it will need to be combined with an independent clause to create a complex sentence. 

This blog post features sentence examples for simple sentences, complex sentences, compound sentences, and compound-complex sentences.

Dependent clauses are considered sentence fragments because they cannot stand alone. Other sentence fragments are missing a either subject or a verb.

What Is an Independent Clause?

An independent clause can stand alone as a complete sentence. It contains a complete thought. 

An independent subject contains a subject and a predicate.

The following example illustrates an independent clause in a simple sentence structure that stands alone as a complete thought:

The dog barked.

The 4 Main Different Types of Sentences

There are 4 main different types of sentences:

  • Simple Sentences
  • Compound Sentences
  • Complex Sentences
  • Compound-Complex Sentences

Each type of sentence structure contains a dependent clause or an independent clause.

What Is a Simple Sentence?

A simple sentence contains a single independent clause. It can stand alone because it expresses a complete thought. 

‘The cat purred’ is a simple sentence. 

This sentence contains a subject, cat. To find the subject of the sentence, we ask, “What (verb)?” In other words, “What purred?”

In addition, this subject contains a verb. To find the verb we ask, “The (subject) did what?” The answer would be, “purred”. 

The word ‘the’ is an article or modifying word, that tells us more information. Which cat? “The”

What Are Compound Sentences? 

 A compound sentence contains two or more independent clauses.

These independent clauses are joined by a coordinating conjunction.

Examples of compound sentences include:

The dog barked and the cat purred.

A dog barked but a cat purred.

What Are Complex Sentences?

Complex sentences contain one independent clause and one or more dependent clauses. 

Subordinating conjunctions connect independent and dependent clauses.

Examples of complex sentences include:

  • After lunch, we went to recess.
  • I won’t eat dessert until I’ve finished dinner.
  • Although it was cold outside, she didn’t wear her coat.

What Are Compound-Complex Sentences?

Compound-complex sentences contain at least one dependent clause and two or more independent clauses

Need some examples of compound-complex sentences?

  • I went to school, and I brought my gym clothes with me because we had gym class.
  • The fifth graders had a science test, but they didn’t get a chance to study because there was an assembly.
