Unlock the Secrets of Subordinating Conjunctions You Need to Know!

私たちの投稿が好きですか？今すぐシェア

Have you ever struggled to connect your ideas smoothly in English? Maybe you’ve written two short sentences and wondered, How can I make this sound more natural? Well, subordinating conjunctions are here to help! These special words, like ‘although,’ ‘since,’ ‘while,’ ‘because,’ and ‘if,’ help connect two ideas in a logical way. They show relationships between thoughts, such as cause and effect, contrast, time, and condition. If that sounds complicated—don’t worry! By the end of this blog, you’ll feel confident using subordinating conjunctions in your own writing and conversations. Let’s explore them step by step!

What Are Subordinating Conjunctions?

A subordinating conjunction is a word that connects an independent clause (a complete sentence) with a dependent clause (a sentence that doesn’t make sense on its own).

Here’s a simple example:

  • I stayed inside because it was raining.

‘I stayed inside’ = a complete sentence.

‘Because it was raining’ = not a complete sentence

‘Because’ = subordinating conjunction, linking the two ideas.

Without ‘because,’ the second part wouldn’t make sense. That’s the magic of subordinating conjunctions—they link thoughts smoothly and logically!

Types of Subordinating Conjunctions

Subordinating conjunctions can express different relationships between ideas. Let’s look at the most common ones with examples.

1. Cause and Effect (Why Something Happens)

These conjunctions explain why something happened.

Common words: because, since, so that

例を挙げよう：

  • I am taking an English class in London because I want to improve my speaking skills.
  • Since it’s a sunny day, we are going to the park.
  • I will explain it so that you can understand it better.

👉 Tip: ‘Because’ is more common in spoken English, while ‘since’ and ‘as’ are more formal.

2. Contrast or Concession (Showing Differences or Surprises)

These words show contrast or an unexpected result.

Common words: although, though, even though, whereas, while

例を挙げよう：

  • Although I was tired, I kept studying.
  • He loves tea, whereas she prefers coffee.
  • While I enjoy learning grammar, I find pronunciation difficult.

👉 Tip: ‘Although’ and ‘even though’ are used in a similar way. ‘Even though’ is stronger and more emphatic.

3. Time (When Something Happens)

These words connect actions and show when they happen.

Common words: when, while, before, after, until, as soon as

例を挙げよう：

  • I listened to music while studying.
  • Please call me as soon as you arrive.
  • We went for lunch after the class finished.

👉 Tip: If you start a sentence with one of these conjunctions, put a comma before the second part:

Before I moved to London, I searched for an English learning course near me.

4. Condition (What If…?)

These conjunctions describe a condition—something that must happen first.

Common words: if, unless, provided that, as long as

例を挙げよう：

  • If you study hard, you will pass the exam.
  • I won’t go outside unless it stops raining.
  • You can join the trip as long as you finish your homework.

👉 Tip: ‘Unless’ means ‘if not.’ So instead of saying, ‘If you don’t hurry, you’ll be late,’ you can say, ‘Unless you hurry, you’ll be late.’

5. Comparison (Showing Similarities or Differences)

A comparison clause is used to compare two things.

Common words: than (for differences), as (for equality or similarity), the more / the less

例を挙げよう：

  • The language courses in London are more interesting than I expected.
  • She speaks English better than I do.
  • He is as patient as his mother.
  • The more you practice, the better you will become.

👉 Tip: When using ‘than’ for comparison, avoid repeating unnecessary words. Instead of saying, “She speaks English better than I speak English,” just say, “She speaks English better than I do.”

How to Use Subordinating Conjunctions Correctly

Now that you know different types of subordinating conjunctions, let’s focus on word order.

You can put the subordinating conjunction in the middle or at the beginning of a sentence:

  • I stayed inside because it was raining.
  • Because it was raining, I stayed inside.

👉 Tip: If the dependent clause comes first, add a comma before the main sentence.

Common Mistakes (And How to Avoid Them!)

    1. Forgetting the second part
      • Although I was tired. (This is incomplete!)
        Although I was tired, I kept studying.
    2. Using a subordinating conjunction with just one sentence
      • I didn’t go out. Because it was raining.
        I didn’t go out because it was raining.
    3. Confusing ‘while’ and ‘whereas’
      • I like football, while my brother prefers basketball.
        I like football, whereas my brother prefers basketball. (‘Whereas’ shows contrast.)
      • Whereas I was waiting, she arrived.
        While I was waiting, she arrived. (‘While’ refers to time.)
