Subordinating conjunctions are words that link two parts of a sentence, showing how one part depends on the other. These words help to join a less important idea (a dependent clause) to a more complete thought (an independent clause).
By using subordinating conjunctions, you can create more interesting and detailed sentences. They help explain why something happens, when it happens, or under what conditions, making your writing clearer and smoother.
What is a Subordinating Conjunction?
A subordinating conjunction is a word that connects a dependent clause (incomplete thought) to an independent clause (complete thought).
It shows the relationship between the two clauses and indicates that one clause is less important or subordinate to the other.
- I stayed home because it was raining.
- She smiled although she was nervous.
- You can go if you finish your homework.

How to Use Subordinating Conjunctions
Subordinating conjunctions are used to connect a dependent clause (incomplete thought) with an independent clause (complete thought). They show relationships like cause, effect, time, place, condition, or contrast.

1. Identify the Relationship
Understand whether the subordinating conjunction is showing cause, time, condition, etc.
2. Place the Subordinating Conjunction
It can be at the beginning or in the middle of the sentence.
3. Use a Comma if Needed
- When the subordinating conjunction starts the sentence, use a comma after the dependent clause.
- No comma is needed if the dependent clause comes second.
Examples
