What Are Conjunctions?
Conjunctions are words that connect other words, phrases, or clauses within a sentence. They help join ideas and show the relationship between them. Without conjunctions, sentences would be choppy and disorganized.
There are three main types of conjunctions: coordinating, subordinating, and correlative. Each type serves a different purpose in sentence construction.
I like coffee and tea.
I like coffee and tea.
Combining two nouns.
Coordinating Conjunctions
Coordinating conjunctions connect words, phrases, or independent clauses that are of equal importance. The most common coordinating conjunctions are: for, and, nor, but, or, yet, so. Remember them with the acronym FANBOYS.
They can join two simple sentences or connect items in a list.
| Coordinating Conjunction | Usage |
|---|---|
| For | Reason or cause |
| And | Addition |
| Nor | Negation addition |
| But | Contrast |
| Or | Choice |
| Yet | Contrast or unexpected result |
| So | Result or effect |
She was tired, but she finished her work.
She was tired, but she finished her work.
Shows contrast between two ideas.
Do you want coffee or tea?
Do you want coffee or tea?
Offers a choice between two options.
Subordinating Conjunctions
Subordinating conjunctions connect a dependent clause to an independent clause, showing a relationship such as time, cause, condition, or contrast. Common subordinating conjunctions include: because, although, since, if, when, while, after, before, unless.
The dependent clause cannot stand alone, so the subordinating conjunction links it to the main clause.
I stayed home because it was raining.
I stayed home because it was raining.
Shows cause and effect.
Although she was tired, she went to the party.
Although she was tired, she went to the party.
Expresses contrast between two clauses.
Correlative Conjunctions
Correlative conjunctions are pairs of conjunctions that work together to connect balanced words, phrases, or clauses. They always come in pairs. Examples include: either...or, neither...nor, both...and, not only...but also, whether...or.
They emphasize the relationship between the elements they connect.
Either you come with me, or I will go alone.
Either you come with me, or I will go alone.
Shows a choice between two options.
She is not only smart but also hardworking.
She is not only smart but also hardworking.
Adds emphasis by connecting two qualities.
Punctuation with Conjunctions
When using coordinating conjunctions to join two independent clauses, a comma is placed before the conjunction. For example:
I wanted to go for a walk, but it started raining.
I wanted to go for a walk, but it started raining.
Comma separates two independent clauses joined by "but".
When conjunctions connect words or phrases (not full clauses), no comma is needed:
She bought apples and oranges.
She bought apples and oranges.
No comma between two nouns joined by "and".
Subordinating conjunctions do not require a comma when the dependent clause follows the independent clause. However, if the dependent clause comes first, use a comma after it:
Because it was late, we decided to leave.
Because it was late, we decided to leave.
Comma after introductory dependent clause.
We decided to leave because it was late.
We decided to leave because it was late.
No comma needed when dependent clause follows.
Common Mistakes
Many learners confuse conjunctions, especially when joining clauses. Here are some common pitfalls:
- Comma splice: Incorrectly joining two independent clauses with only a comma and no conjunction.
- Using "and" instead of "but": Using "and" to show contrast instead of "but".
- Misplacing conjunctions: Placing correlative conjunctions incorrectly or using only one part of the pair.
Incorrect: I was hungry, I ate dinner.
Incorrect: I was hungry, I ate dinner.
Comma splice without conjunction.
Correct: I was hungry, so I ate dinner.
Correct: I was hungry, so I ate dinner.
Proper use of coordinating conjunction with comma.
Practice Examples
Try identifying and using different conjunctions in the following sentences.
I want to go to the park, but it is raining.
I want to go to the park, but it is raining.
Contrast between desire and condition.
She will call you after she arrives.
She will call you after she arrives.
Time relationship using subordinating conjunction.
Neither the blue shirt nor the red one fits me.
Neither the blue shirt nor the red one fits me.
Using correlative conjunctions to connect two options.
Write your own sentences using these conjunctions to practice effectively.
Tips for Remembering Rules
Here are some handy tips to master conjunctions in English:
- Memorize the FANBOYS acronym for coordinating conjunctions.
- Remember that subordinating conjunctions introduce dependent clauses.
- Always use both parts of correlative conjunctions together.
- Use commas before coordinating conjunctions joining two independent clauses.
- Practice by combining simple sentences into complex ones using conjunctions.
Practice regularly and read examples to see conjunctions in context. This will help you use them naturally and correctly.
