Subordinating Conjunctions

The Boss and the Minion Relationship

Subordinating conjunctions create unequal relationships between clauses. One clause is the boss (independent), and the other is the minion (dependent). The subordinating conjunction introduces the minion clause that can't survive on its own.

How They Work:

Independent clause + subordinating conjunction + dependent clause

OR

Subordinating conjunction + dependent clause, + independent clause

When the dependent clause comes first, use a comma!

Type Conjunctions Example
Time when, while, before, after, since, until, as soon as I'll call you when I arrive.
Reason because, since, as I stayed home because I was ill.
Condition if, unless, provided that If it rains, we'll stay inside.
Contrast although, though, even though, whereas, while Although it's cold, I'm going out.
Purpose so that, in order that I speak slowly so that you understand.
Result so...that, such...that It was so cold that I couldn't feel my fingers.

Common Subordinating Conjunctions in Action

1. Time Relationships:

  • "When I was young, I believed in Santa." (Specific time)
  • "I'll wait until you're ready." (Duration)
  • "After the movie ended, we went home." (Sequence)
  • "I've lived here since I was born." (Starting point)

2. Cause and Effect:

  • "I'm tired because I didn't sleep well." (Reason)
  • "Since you're here, let's start the meeting." (Reason - more formal)
  • "As it was getting late, we decided to leave." (Reason - simultaneous)

3. Contrast and Concession:

  • "Although I'm tired, I'll finish this work." (Unexpected contrast)
  • "Even though it's expensive, I'll buy it." (Strong contrast)
  • "While I like coffee, I prefer tea." (Mild contrast)

Comma Rules (Pay Attention!)

When to Use Commas:

  • Dependent clause first: "Because I was tired, I went to bed."
  • Independent clause first: "I went to bed because I was tired." (No comma)
  • Exception: Always use comma with "although," "though," "even though"

Tricky Pairs - Don't Mix These Up!

Often Confused Correct Usage Example
Since vs Because Since = more formal/time; Because = reason Since you asked... / Because I'm hungry...
While vs When While = duration; When = specific moment While I was cooking... / When I finished...
If vs Unless If = positive condition; Unless = negative condition If you study... / Unless you study...

Don't Be a Plonker - Common Mistakes

❌ Wrong:

  • "Because I was tired." (Incomplete - dependent clause alone)
  • "Although I'm busy but I'll help you." (Don't use 'but' with 'although')
  • "When I arrived I called you." (Missing comma)

✅ Right:

  • "Because I was tired, I went to bed." (Complete sentence)
  • "Although I'm busy, I'll help you." (No 'but' needed)
  • "When I arrived, I called you." (Comma after dependent clause)
