Rules for Using Subordinating Conjunctions
- If the dependent clause comes first, use a comma after it:
If you are late, let me know. - No comma is needed if the dependent clause comes after the main clause:
Let me know if you are late. - Do not use a comma before the subordinating conjunction in the middle of a sentence.
- Always ensure a dependent clause is joined to an independent clause so the sentence makes sense.

FAQs on Subordinating Conjunctions in English Grammar
1. What is a subordinating conjunction?
A subordinating conjunction is a word that connects a dependent clause to an independent clause and shows their relationship. It introduces a subordinate (dependent) clause that cannot stand alone as a complete sentence.
- Common subordinating conjunctions include because, although, if, when, while, since, after, before, unless.
- Example: Because it was raining, we stayed inside.
- "Because it was raining" is the dependent clause.
2. What are some common examples of subordinating conjunctions?
Common subordinating conjunctions include words that show time, cause, condition, contrast, and purpose. These words connect clauses in complex sentences.
- Time: after, before, when, while, until
- Cause/Reason: because, since, as
- Condition: if, unless
- Contrast: although, though, whereas
- Purpose: so that, in order that
3. How do subordinating conjunctions work in a sentence?
Subordinating conjunctions work by introducing a dependent clause and linking it to an independent clause to form a complex sentence. The dependent clause adds extra information but cannot stand alone.
- Structure: Subordinating conjunction + dependent clause + main clause
- Example: If you study hard, you will pass the exam.
- The dependent clause explains the condition for the main clause.
4. What is the difference between subordinating and coordinating conjunctions?
The main difference is that subordinating conjunctions join unequal clauses, while coordinating conjunctions join equal clauses. Subordinating conjunctions create complex sentences, while coordinating conjunctions create compound sentences.
- Subordinating example: Although she was tired, she finished her work.
- Coordinating example: She was tired, but she finished her work.
- Coordinating conjunctions include for, and, nor, but, or, yet, so (FANBOYS).
5. Do you need a comma with a subordinating conjunction?
A comma is needed when the dependent clause comes before the independent clause, but not usually when it comes after. Comma rules depend on clause position.
- Comma needed: Because she was late, she missed the bus.
- No comma: She missed the bus because she was late.
6. Can a sentence start with a subordinating conjunction?
Yes, a sentence can start with a subordinating conjunction as long as it includes a complete independent clause. Starting with words like "because" or "although" is grammatically correct when the sentence is complete.
- Correct: Although it was cold, we went swimming.
- Incorrect (fragment): Although it was cold.
7. What is a subordinate clause?
A subordinate clause (or dependent clause) is a group of words with a subject and verb that cannot stand alone as a complete sentence. It depends on an independent clause for meaning.
- Introduced by a subordinating conjunction.
- Example: I left early because I was tired.
- "Because I was tired" cannot stand alone.
8. What types of relationships do subordinating conjunctions show?
Subordinating conjunctions show relationships such as time, cause, condition, contrast, and purpose between clauses. They explain how one idea depends on another.
- Time: when, after, before
- Cause: because, since
- Condition: if, unless
- Contrast: although, though
- Purpose: so that
9. What are common mistakes with subordinating conjunctions?
A common mistake with subordinating conjunctions is creating a sentence fragment by leaving the dependent clause incomplete. Learners also misuse commas or confuse them with coordinating conjunctions.
- Fragment: Because I was hungry.
- Correct: Because I was hungry, I made a sandwich.
- Avoid adding unnecessary commas after short dependent clauses placed at the end.
