If you want to express deeper thoughts and add more meaning to your sentences, then learning complex sentences is essential. They help you sound more fluent and connect ideas clearly, whether you are using them in your writing or speaking conversations.
A complex sentence is a sentence that has one independent clause and at least one dependent clause.
Example:
- I stayed home because it was raining.
Here, “I stayed home” is the independent clause (it can stand alone), and “because it was raining” is the dependent clause (it cannot stand alone).
Key Features of Complex Sentences
A complex sentence:
- Includes one independent clause
- Has one or more dependent clauses
- uses subordinating conjunctions to connect the clauses
- Expresses cause, time, condition, contrast, purpose, and more
Parts of a Complex Sentence
A complex sentence must have two parts:
- Independent Clause
- Dependent Clause
For example:
- She went to bed because she was tired.
1. Independent Clause
A complete sentence that makes sense on its own.
Example:
- She went to bed.
2. Dependent Clause
A group of words that depends on the main sentence to make sense.
Example:
- because she was tired.
Common Subordinating Conjunctions
Subordinating conjunctions are used to connect dependent clauses to independent ones. Here are some of the common subordinating conjunctions and their purpose of using them in sentences:
- Cause
- becuase, since, as
- Time
- when, before, after, while, until
- Condition
- if, unless, even if, whether
- Contrast
- although, though, whereas, while
- Purpose
- so that, in order that
Sentence Structure: Where to Place the Clauses
You can place the dependent clause before or after the independent clause.
Dependent clause first (use a comma)
- Because I was tired, I went to bed early.
Independent Clause First (no common needed)
- I went to bed early because I was tired.

Frequently Asked QuestionsÂ
Can a sentence have more than one dependent clause?

Do all dependent clauses begin with subordinating conjunctions?
Most of them do. Subordinating conjunctions signal the start of a dependent clause.
Can I use “and” or “but” in a complex sentence?
Yes, but those are coordinating conjunctions. Use them only if you are combining another independent clause.
