Advanced Grammar – Coordinating Conjunctions

Remember our Introduction to Connectors? Let’s look deeper into the first category: Coordinating Conjunctions.

These conjunctions connect words, phrases and clauses. They are usually found in the middle of a sentence with a comma (,) just before the conjuction, or at the beginning of the sentence.

Addition Alternative Cause-Effect Condition Contrast
And or so  or else  but
Also not for until  yet


First, we will explain the difference between coordination and subordination: coordination means both parts of the sentence are equal. Subordination means one clause, or part of the sentence, is more important than the other.

Coordination: “Diana loved studying maths, but Julia hated it.”
Subordination: “Diana only enjoyed math if Julia was there.”

There are three ways of using Coordinating Conjunctions:

1. Connecting two main clauses
When you connect two main clauses, use a comma. The clauses are underlined.

Example: “When I get home the dog is on the sofa and the cat is on the bed

2. Connecting two items
Connect two gramatical units, but not clauses.

Example: “My hat’s great: it has flowers and a ribbon

3. Connecting three or more items in a series. 
This way is similar to number two. You separate the items with a comma, except the last.

Example: “What I do when I get home is watch TV, cook supper and go to bed.

So now we will learn when we use each connector…


Used to introduce a statement that explains why a preceding statement is true. Usually, we use “because” instead of “for”, however.
Example: “I know he went to the party, for I saw him there”


1 - Used to join words or groups of words.
Example: “My dog is black and white.

2 - Used to describe an action that is repeated or that occurs for a long time.
Example: ” The dog barked and barked and barked.

3 - Used to describe actions that occur at the same time.
Example: “They sat and waited for hours for the doctor to come”

4- Used to describe an action that occurs after another action.
Example: “Ok, we will travel for 3 hours and then stop to eat”

5- Used to describe an action that occurs after and is caused by another action.
Example: “I asked her to buy me some sweets and she did.


Used after a negative statement to introduce a related negative word or statement. It’s not often used on its own.
Example: “Laura didn’t eat her meat, nor did she want the vegetables”


1 - Used to introduce a statement that adds something to a previous statement and usually contrasts with it in some way
Example: “Gina doesn’t like James, but I do”

2 - Synonymous of  “other than”.
Example: “When the weather got worse we had no choice but to go home”


1 - used to introduce another choice or possibility
Example: “Would you like tea or coffee?”

2 - Used in negative statements to introduce something else that is also not true.
Example: “We couldn’t stop or get out of the taxi”

3 - Used to say what will happen if a specified thing is not done.
Example: “You have to go to the job interview or you won’t get a job”

4 - Used to introduce the reason why something said previously is true.
Example: “He must have passed the exam or he would be upset”

5 – Used to introduce a word or phrase that defines or explains what another word or phrase means.
Example: “Adiós, or in English goodbye, is what we say to each other when we’re leaving”


Used to introduce a statement that adds something to a previous statement and usually contrasts with it in some way.
Example: “My aunt designs high quality yet affordable clothes”


1 - For that reason : and therefore
Example: “The film was very bad, so we left after 10 minutes”

2 - Used to say the reason for something.
Example: “Please be quiet so everyone can read peacefully”

3 - Used in speech to introduce a statement or question.
Example: “So, finally we meet!”

Great! That’s one of the four Sentence Connector types.

Try to practice by using them in sentences; stop yourself when you are about to say or write two short sentences which you could connect for a richer language.
