The structure of the sentence is the blend of two or more than two types of sentence. Good writing requires the basic understanding of the usage of sentence structures to make high quality content that Google prefers to show others.

What are compound-complex sentences?

A compound-complex sentence is a type of sentence that combines elements of both compound and complex sentences. A compound sentence has at least two independent clauses joined by using a comma, semicolon or conjunction

In the English Language, the grammar and the rules of sentence structure are predefined. It's a little bit complex while implementation in the writing but necessary to understand its usage and importance. 

The blend of complex and compound sentences makes compound-complex sentences. Such as:

  • Mixture of two or more independent clauses
  • Complete sentences that stand alone
  • Blend of one or more dependent clauses

This structure allows writers to convey multiple related thoughts in a single,compatible sentence that enhance the depth and clarity of their writing.

In constructing a compound-complex sentence, you need to combine clauses using coordinating conjunctions like for, and, nor, but, or, yet, so and subordinating conjunctions as because, although, since, unless, etc.

4 main elements of compound-complex sentences

The formation of compound-complex is hard and a bit tricky to learn and apply in the sentences. Sometimes it creates ambiguity by using synonyms in a sentence. 

At beginner level, we need to understand how to use and with whom the clauses used to make a clear and sensible sentence.

The following are some main elements of compound-complex sentences. 

1. Independent clauses

These are the complete sentences that stand alone. They express a complete thought and have a subject and a verb.

2. Dependent clauses 

These clauses do not stand alone as they don’t express a complete thought. Some subordinating conjunctions (e.g., because, although, since, if, when).

3. Coordinating conjunctions

The words that join independent clauses (e.g., for, and, nor, but, or, yet, so) are said to be coordinating conjunctions. 

4. Subordinating conjunctions

The words that introduce dependent clauses (e.g., because, although, since, unless, while) are subordinating conjunctions. 

3 simple steps to construct compound-complex sentences

Let’s discuss some steps that help to construct compound-complex sentences. 

1. Identify independent clauses

Firstly, start by writing two independent clauses. 

2. Add a dependent clause

Now, use a dependent clause to add more detail or context to one of the independent clauses.

3. Use appropriate conjunctions

Lastly, join the clauses using coordinating and subordinating conjunctions like and, for, because, while, not, unless, yet and so etc. 

By following these steps, you will easily make contextual and clear compound-complex sentences without any confusion. 

Tips and tricks of using compound-complex sentences

Compound-complex sentences are used to:

  • Show the relationship between different ideas and provide information by using declarative sentences.
    Example: The sun was setting, and the sky turned orange because the park was quiet.
  • Provide more detail and depth to writing by combining multiple ideas into a single sentence.
  • Improves the flow of writing and is also used to give commands, instructions by implementing the structure of imperative sentences.
    We combine commands or requests with dependent clauses to add more context or detail.
    Example: Finish your dinner, and come to me before the rain starts.
  • Compound-complex sentences are the best way to show emotions and thoughts by adding facts into it.
    Let’s just write an exclamatory sentence to show its relationship with compound-complex sentences. Example: What a victory it was, and we celebrated all night, although we were exhausted!
