- Correlative conjunctions
For example, and, but, and or are coordinating conjunctions. Because, although, if, and when are subordinating conjunctions. Pairs such as either…or and neither…nor are correlative conjunctions.
The Origin of What Is a Conjunction?
The word conjunction comes from the Latin word coniunctio, meaning “joining” or “connection.” It comes from the Latin verb coniungere, meaning “to join together.”
The word entered English through Old French and was used as a grammatical term to describe words that join parts of a sentence.
The name fits its function very well. A conjunction literally helps join language elements together.
For example:
Sarah studied hard and she passed the test.
Here, and joins two ideas.
The spelling conjunction is standard in modern English. Unlike some words that have different British and American spellings, conjunction does not have a separate US or UK spelling.
British English vs American English Spelling
The word conjunction is spelled the same way in both British and American English.
| Feature | British English | American English |
|---|---|---|
| Singular | conjunction | conjunction |
| Plural | conjunctions | conjunctions |
| Adjective | conjunctive | conjunctive |
| Example | “And” is a conjunction. | “And” is a conjunction. |
| Spelling difference | None | None |
There is no standard British spelling such as conjunktion and no American alternative spelling.
Conjunction vs Conjunctions
The difference is simply singular and plural:
- Conjunction = one
- Conjunctions = more than one
Examples:
And is a conjunction.
And, but, and or are conjunctions.
Common Conjunction Words
| Conjunction | Common function | Example |
|---|---|---|
| and | Adds information | Tom and Jack came. |
| but | Shows contrast | I tried, but I failed. |
| or | Shows choice | Tea or coffee? |
| so | Shows result | It was late, so we left. |
| because | Gives a reason | I stayed home because I was sick. |
| although | Shows contrast | Although it rained, we went out. |
| if | Shows a condition | If you study, you can pass. |
| when | Shows time | Call me when you arrive. |
Which Spelling Should You Use?
There is no difficult spelling choice with conjunction. Use conjunction in British English, American English, and international English.
For US English
Use:
conjunction
This is the standard American spelling.
For UK and Commonwealth English
Use:
conjunction
The same spelling is standard in British English and commonly used across Commonwealth English.
For Global English
Use:
conjunction
If your website, schoolwork, business documents, or educational material has an international audience, conjunction is the correct spelling.
The bigger issue is not spelling. It is choosing the right conjunction for the relationship between ideas.
For example:
I was tired, but I worked.
But shows contrast.
I was tired, so I went home.
So shows a result.
Common Mistakes with What Is a Conjunction?
Conjunctions are simple words, but they can still cause grammar problems.
Mistake 1: Using “And” When You Need Contrast
Incorrect:
I was tired, and I continued working.
This sentence is possible, but if your main idea is contrast, but is clearer.
Better:
I was tired, but I continued working.
Mistake 2: Confusing “Because” and “So”
Because gives a reason:
I stayed home because I was sick.
So gives a result:
I was sick, so I stayed home.
Do not normally combine them in the same simple structure:
❌ I was sick because so I stayed home.
✅ I was sick, so I stayed home.
Mistake 3: Misusing “Although”
Although already introduces a contrast.
Incorrect:
❌ Although it was raining, but we went outside.
Correct:
✅ Although it was raining, we went outside.
Or:
✅ It was raining, but we went outside.
Using both although and but together in this structure is unnecessary.
Mistake 4: Creating a Sentence Fragment
A subordinating conjunction can introduce a dependent clause.
For example:
❌ Because I was tired.
This is incomplete if it stands alone.
Better:
✅ I went to bed because I was tired.
Or:
✅ Because I was tired, I went to bed.
Mistake 5: Confusing “Either…Or”
Correlative conjunctions usually work in pairs.
Correct:
You can either call me or send an email.
Incorrect:
❌ You can either call me.
The pair is either…or.
Other common pairs include:
- both…and
- neither…nor
- not only…but also
- whether…or
