Subordinating Conjunctions: A Simple Guide with Examples

---

📚 What Are Conjunctions?

A conjunction is a word that joins two parts of a sentence. There are three types:

1. Coordinating conjunctions – join two equal ideas (like and, but, or).

2. Correlative conjunctions – work in pairs (like either…or, neither…nor).

3. Subordinating conjunctions – join a main idea and a dependent idea (like because, if, when).

In this post, we will focus on subordinating conjunctions.

🔍 What Is a Subordinating Conjunction?

A subordinating conjunction is a word that connects a main clause and a subordinate clause (also called a dependent clause).

👉 Main clause: A complete sentence.
👉 Subordinate clause: Not a complete sentence. It depends on the main clause to make sense.

🧩 These conjunctions show the relationship between two ideas — like cause, time, condition, contrast, and more.

📌 Structure of Sentences with Subordinating Conjunctions

You can write sentences using subordinating conjunctions in two ways:

1. Main Clause + Subordinate Clause

👉 I went home because I was tired.

2. Subordinate Clause + Main Clause

👉 Because I was tired, I went home.

✅ Note: When the subordinate clause comes first, use a comma.

🧾 Tips to Remember Subordinating Conjunctions

✅ Tip 1: Think about the question you are answering — is it “when?”, “why?”, “how?”, or “if?”
👉 That helps you pick the right conjunction.

✅ Tip 2: Start small. Use 5–6 common conjunctions like because, if, when, although, before, and since. Use them often.

✅ Tip 3: Mix sentence types in your writing. Don’t only use short sentences. Use subordinating conjunctions to join ideas.

✅ Tip 4: Practice joining ideas from your daily life.
Example:

• I’m tired. I’ll take a break.
  👉 I’ll take a break because I’m tired.
