50 Useful Examples of Complex Sentences

In this lesson, we will discuss the 50 useful examples of complex sentences in English grammar. One of the first things we need to consider when writing a sentence is whether or not it is complex. A complex sentence consists of one independent clause and one or more subordinate clauses. Let us know the definition of a complex sentence.

What Is a Complex Sentence?

To define a complex sentence, think about it this way:

“Jane had her brother take care of the dog”

This sentence has one subject and one verb. “Jane” is the subject, and “had” is the verb. So it’s not a complex sentence because there is only one independent clause.

On the other hand, this sentence is a complex sentence:

“While Jane was making dinner, she remembered that she forgot to feed the dog.”

In this sentence, there are two subjects (Jane and she) and two verbs (make and remember). This makes it a complex sentence because this sentence contains a subordinate clause and an independent clause that have their own subjects and verbs.

Final Thoughts

Complex sentences are essential to the English language, allowing us to express a wide range of ideas and convey complex relationships between different clauses.

We can describe conditions, contrast ideas, and demonstrate cause-and-effect relationships by combining independent and dependent clauses. Understanding complex sentences improves our capacity for clear idea expression and effective communication.

Complex sentences allow us to convey more complex meanings and produce richer, more interesting dialogue, whether we employ them in writing or speaking. Our ability to understand and use complicated sentences broadens our language skills and enhances our overall fluency and proficiency in English.
