Use Complex Sentences for Better Writing

With experts raving about the elegance of simple sentences, you might be tempted to abandon other types of sentences. However, the truth is that the best articles and essays have a blend of different kinds of sentences.

Your work becomes boring and monotonous when you use only simple sentences. A complex sentence generator can rejig your writing for a dynamic flow.

This article breaks down complex sentences for you to understand their different components and how to write them. It also introduces you to other complex sentence generators.

What Are Complex Sentences?

A complex sentence is any sentence containing an independent clause and at least one subordinate clause. Sounds complex? Let’s look closer. 

You can quickly identify complex sentences because they usually have subordinating conjunctions introducing the subordinate clause. Examples of subordinating conjunctions are: although, after, before, when, while, and since

Independent clauses are so named because they can stand on their own and make complete sense. We can’t say the same of a subordinate clause.

Examples of Complex Sentences

  • I’ll give you $10 if you come early.

In this sentence, “I’ll give you $10” is the independent clause, while “if you come early” is the subordinate or dependent clause.

  • Call me when you need me.

Here, “call me” is the independent clause, while “when you need me” is the dependent clause.

  • You get a complimentary pass if you help the kids.

Here, “You get a complimentary pass” is the independent clause, while “if you help the kids” is the dependent clause.

Did you notice how the dependent and subordinate clauses have subjects and verbs? The only difference between the two is that a subordinating conjunction introduces the latter. This makes them reliant on the independent clause to make complete sense. On their own, they are just sentence fragments.

What Is the Best Complex Sentence Generator?

Understanding the basics of complex sentences is good. But you don’t have to go through the process if you can find a tool to do it for you. 

With that said, getting a complex sentence generator is not a straightforward task.

The major problem is that you won’t find a tool for creating complex sentences. However, it’s not impossible. There are a bunch of online AI tools that can quickly expand your complex sentences and make them better.


INK AI is a tool with many parts. Essentially, it is a tool that improves every aspect of your writing. You’ll especially find the AI expand tool handy for perfecting your complex sentences. It expands the sentences and makes them more vivid. We took the tool for a spin, using our previous examples. See the results below:

  • If you arrive early, I will give you $10.
  • Do not hesitate to call me when you need me.
  • If you help the children, you’ll receive a complimentary pass.

This tool did a good job. It maintained the complex sentence structure, adding a few extra words into the fray without altering its overall meaning.

 The hallmark of great complex sentence generators is that they reword your sentence and maintain the meaning and complex structure.

This online tool is ideal for those looking for a free tool to generate complex sentences. This web-based service is a tool that rephrases sentences into more complex or convoluted alternatives. We tested our sentences with this tool. Here’s the result:

  • I’ll give you $10 if you come early.

This tool’s output isn’t mind-blowing. The first sentence remains unchanged, while the choice of words in the last two could have been better. Overall, it is an adequate tool for the task because you don’t have to pay to use it.


Quillbot has been around for a while, and it is one of the best tools around. It has seven paraphrasing modes, including the standard, fluency, and expand modes. The expand mode is only accessible on the paid plan. Nevertheless, we tried out our samples in the free standard mode. Here’s the result:

  • I will give you $10 if you arrive earlier.
  • If you need me, give me a call.

  • Name me while you need me.
  • You get a complimentary bypass if you assist the youngsters.

The output is fairly decent since it can be used without paying. However, you’ll need to proofread the output.
