Subordinating conjunctions are essential tools in the English language, used to connect dependent clauses to independent clauses, creating more complex and meaningful sentences. These words, such as “because,” “although,” and “while,” help establish relationships like cause and effect, time, and contrast. By using subordinating conjunctions, writers can add depth, clarity, and variety to their sentences. Understanding how to use them effectively is a key step toward improving your writing skills and mastering sentence structure. In this article, we’ll explore what subordinating conjunctions are, why they matter, and how to use them with confidence.
What Is a Subordinating Conjunction?
Subordinating conjunctions are words or phrases that connect a dependent clause to an independent clause, showing the relationship between the two. They help form complex sentences by adding extra details. They also help clarify the purpose, time, cause, condition, or contrast within a sentence. Without subordinating conjunctions, dependent clauses would not make sense on their own, as they rely on the independent clause to complete their meaning.

Examples:
- “She stayed at home because it was raining.”
- “I will call you when I arrive.”
In these sentences, “because” and “when” are subordinating conjunctions that introduce dependent clauses, providing reasons and time references, respectively.
Subordinating conjunctions differ from coordinating conjunctions in their function. While coordinating conjunctions (like “and,” “but,” or “or”) join clauses of equal importance, subordinating conjunctions introduce a dependent clause, emphasizing its relationship to the main idea.
Common Subordinating Conjunctions
Here are some subordinating conjunctions, grouped by function, with examples to help you remember how to use them:

Functions of Subordinating Conjunctions
Subordinating conjunctions are vital for building sophisticated and meaningful sentences. They not only connect clauses but also establish logical relationships between them. Here’re several key functions of subordinating conjunctions:

1. Add Depth and Complexity
Subordinating conjunctions are instrumental in creating complex sentences by combining an independent clause with a dependent clause. This combination allows writers to present additional information or context, enriching their writing.
Examples:
- Simple sentence: “She was tired.”
- Complex sentence: “Although she was tired, she finished her work.”
2. Show Relationships Between Ideas
Subordinating conjunctions clarify logical relationships between ideas, such as cause and effect, contrast, time, condition, or place.
Examples:
- Cause and Effect: “The crops thrived since it rained heavily.”
- Time: “We’ll go out after the storm passes.”
- Condition: “You’ll succeed if you work hard.”
- Contrast: “Although he was nervous, he gave a great speech.”
- Place: “Let’s meet where we had lunch last week.”
3. Enhance Clarity and Coherence
By linking related ideas, subordinating conjunctions improve the flow and readability of writing, making it easier for readers to follow the author’s train of thought.
Example:
- “We can start the meeting after John arrives.”
Tips for Using Subordinating Conjunctions
Proper use of subordinating conjunctions is essential for clear and effective writing. Here are some guidelines to follow:
1. Pay Attention to Clause Order
A dependent clause introduced by a subordinating conjunction can appear before or after the main clause. When it precedes the main clause, it’s typically followed by a comma.

Examples:
- Dependent clause first: “Because it was raining, we stayed indoors.”
- Independent clause first: “We stayed indoors because it was raining.”
2. Avoid Sentence Fragments
Ensure that the dependent clause is always connected to an independent clause to form a complete sentence.
Examples:
- Fragment: “Although she was hungry.”
- Complete sentence: “Although she was hungry, she waited for dinner.”

3. Don’t Overuse Them
Balance is key in writing. Overloading sentences with too many subordinating conjunctions can make them overly complex and difficult to read.

Examples: Avoid Overusing Subordinating Conjunctions
- Overuse: “Although he wanted to stay, and because it was getting late, and since he had an early meeting, he decided to leave.”
- Improved: “Although he wanted to stay, he decided to leave because it was getting late and he had an early meeting.”
How to Use Subordinating Conjunctions in Sentences
Using subordinating conjunctions effectively requires an understanding of sentence structure and the relationship between clauses. Here’s a step-by-step guide to help construct sentences with subordinating conjunctions.

1. Understand Clause Placement
A subordinating conjunction connects two types of clauses:
- Independent Clause: A complete thought that can stand alone as a sentence.
- Dependent Clause: An incomplete thought that relies on the independent clause to make sense.
For example:
- Independent Clause: “I stayed home.”
- Dependent Clause: “Because it was raining.”
→ When combined: “I stayed home because it was raining.”
2. Positioning Subordinating Conjunctions
Subordinating conjunctions can appear at the beginning or in the middle of a sentence.
- At the beginning: When the sentence starts with a dependent clause, it is followed by a comma.
- Example: “Because it was raining, I stayed home.”
- In the middle: When the dependent clause follows the independent clause, no comma is needed.
- Example: “I stayed home because it was raining.”
3. Punctuation Rules
- Always use a comma when the dependent clause comes first.
- Correct: “Although I was tired, I finished my homework.”
- Do not use a comma when the dependent clause comes after the independent clause.
- Correct: “I finished my homework although I was tired.”
By mastering the placement of subordinating conjunctions and following punctuation rules, you can create sentences that are clear, cohesive, and expressive. Practice these techniques to enhance your sentence structure and writing style.

Frequently Asked Questions
1. Are subordinating conjunctions and subordinators the same?
Yes, the terms are often used interchangeably. Subordinators refer to the same words (like “because,” “although,” and “if”) that connect dependent and independent clauses.
2. What are comparative conjunctions?
Comparative conjunctions like “than” and “as … as” are used to compare one clause to another. They function as subordinating conjunctions when they introduce dependent clauses.
- Example with “than”: “She is taller than her brother.”
- Example with “as … as”: “He is not as skilled as she is.”
3. Can subordinating conjunctions connect two independent clauses?
No, subordinating conjunctions only connect a dependent clause to an independent clause. For joining two independent clauses, you need coordinating conjunctions or punctuation like a semicolon.
4. Do subordinating conjunctions always require a dependent clause?
Yes, subordinating conjunctions must introduce a dependent clause. Without it, they cannot function properly in a sentence.
