You use coordinating conjunctions in most of your writing—but what exactly are they, and how do you use them properly?
If you want to understand coordinating conjunctions so you can use them correctly every time, you're in the right place.
Let’s jump right in.
A coordinating conjunction is a word that joins two ideas, phrases, or clauses of equal importance in a sentence.
Here are the seven coordinating conjunctions:
Coordinating conjunctions help you connect your ideas in a logical way.
Let’s take an example:
“The kittens were sleeping when the baby cried.”
The second part of the sentence (when the baby cried) is not related to what’s happening in the first part.
Therefore, you’ll need a coordinating conjunction like “but” or “yet” to connect the two events and give meaning to your sentence.
Let’s add a coordinating conjunction and change the sentence to: “The kittens were sleeping, but they woke up when the baby cried.”
Here, we’ve used the coordinating conjunction “but” to strengthen the sentence.
We’ll go into more examples later. But, first, let’s give you a fun way to remember the main coordinating conjunctions.
Oh, boy! You’ll be a fan.
I'm not just being enthusiastic about coordinating conjunctions.
Let’s review the list of coordinating conjunctions again. This time, we’ll bold the first letter of each word:
If you look at the bold letters above, they form the word FANBOYS.
You can use FANBOYS as an acronym to remember these seven coordinating conjunctions. Of course, feel free to put your own spin on it and make it BOYFANS.
If you love Scrabble, you probably have more tricks up your sleeve and can spin it in any way you want. However, FANBOYS is the most commonly used acronym. Memorize it.
Let’s check out more examples of coordinating conjunctions.
These sentences should help you understand how to use all seven FANBOYS coordinating conjunctions:
Let’s try a quick exercise to see if you’ve understood how to use coordinating conjunctions. Fill in the blanks below:
Do you want to go by train, bus, ................ plane?
I hate school, ................ I am always top of the class!
Life is hard, ................ there’s always something to be grateful for.
You are awesome, ................ you are reading this article so intently.
Paul doesn’t do push-ups, ................ does he do any other exercise.
Waiting to see your score? Here are the answers:
Do you want to go by train, bus, or plane?
I hate school, yet I am always top of the class!
Life is hard, but there’s always something to be grateful for.
You are awesome, for you are reading this article so intently.
Paul doesn’t do push-ups, nor does he do any other exercise.
We use all seven of these conjunctions all the time. However, these three are used more than the rest:
You guessed it:
And is the most used. You’ll see it throughout this and virtually any other article. You’ll find but and or in most writing as well.
What about the rest? So is still widely used. Some people consider for archaic (an old-fashioned form of because). Others believe nor is slowly going extinct. And you’ll get lots of content that doesn’t mention yet anywhere.
Let’s go deeper and understand how each of these words is used.
Each of the seven FANBOYS has its own rules. Let’s explore them one by one.
And joins grammatically similar expressions. Examples include:
If you have a list with three or more items, use and before the last one. Avoid using and multiple times in the same list. For instance:
When talking or writing, we use some common expressions that use “and”. We should keep these expressions fixed. Do not change the word order—it'll sound strange.
For example, it’s black and white and not white and black. Here’s more:
In numbers, and is used to separate bigger numbers from those that are smaller than a hundred:
524 is five hundred and twenty-four
2,000,227 is two million, two hundred and twenty-seven
It also separates whole numbers and fractions. For instance, 9½ is nine and a half.
But links two contrasting ideas. It’s easily confused with yet. We’ll talk about yet next so that you can see the difference clearly.
Here are some examples:
But is not always a conjunction. If you use it to mean “apart from”, it becomes a preposition. It’s only a coordinating conjunction when you use it to join contrasting ideas.
Yet shows contrast. However, it’s better used to introduce something shocking or surprising—that’s one simple way to differentiate it from “but”.
Here are some instances of when you might use "yet":
It’s still grammatically correct to replace yet with but. However, yet adds strength to the element of surprise.
When you use yet to signify time or an amount (e.g. "Are we nearly there yet?"), it becomes an adverb and is no longer a coordinating conjunction.
For explains a reason, similar to words like “because” and “as”. Depending on how you use it, for can be a preposition, too. It becomes a coordinating conjunction when you use it to give a reason.
Here are some examples:
In modern writing, many people prefer using “because” instead of “for”. Some reserve its use for formal writing.
So shows the effect of something. It’s another confusing conjunction since it can easily be a subordinate conjunction. Consider it a coordinating conjunction if it connects two equal and independent clauses.
Examples include:
So has multiple uses as well. It becomes an adverb when you use it to qualify a verb or adjective, for instance, “She is so annoying”.
Nor expresses negation. Like and, it links two expressions. However, when using nor, both expressions should be negative.
See it in action below:
Reverse the order of verbs in the second clause when using nor. If the first clause had “did not”, the second clause should have “nor did he”.
When you use “nor” after “neither”, it becomes a correlative conjunction—a set of conjunctions that join ideas. Other examples of correlative conjunctions include “either/or”, “not/but”, and “both/and”, among others.
Or introduces a choice. It can also be used for clarification or to show the result of an action.
Here are some examples:
Use a comma when joining two independent clauses with a coordinating conjunction.
Insert the comma just before the coordinating conjunction as shown in this example:
George is awesome, but he always shows up late.
If you’re writing a long sentence with multiple commas, you can use a semi-colon instead so that you don’t confuse your reader:
Martha really wanted to go to the mixer, meet some potential employers, and explore her options; but she was worried she might miss it altogether as her car was late.
Some instances of “or” do not require a comma:
When writing a list, you can place a comma before “and” or “or”. That is called an Oxford or serial comma. It’s widely used in American English, while British English writers tend to ignore it. You do not commit any grammatical crime by using it or not.
Analyze your target audience before you decide whether to use the Oxford comma. If it’s predominantly American, include it in your writing. If not, then you can choose to omit it.
Here are examples of sentences with the Oxford comma:
If you need to use the Oxford comma in your writing, you can set up a rule in your ProWritingAid Style Guide to remind you.
The most important rule with the Oxford comma is consistency. If you use it once, use it throughout your document. ProWritingAid will make sure your comma use is always consistent.
Yes, you can start a sentence with a coordinating conjunction, regardless of what your teachers may have taught you. Doing that does not break any grammar rules.
You’re probably wondering if this will mess up your writing and create a lot of sentence fragments. It won't, if you do it right.
To avoid sentence fragments, ensure you add a main clause right after the coordinating conjunction. That way, the sentence will not have any syntax errors.
Although it’s okay to start sentences with “and” and “but”, avoid doing so in consecutive sentences. Start with coordinating conjunctions only where it makes sense. To improve flow and readability, switch up the way you begin your sentences throughout your writing.
These two types of conjunctions link words and are both important in proper sentence construction.
The difference is in the strength of what’s being linked. A coordinating conjunction links two elements that have equal strength. Subordinating conjunctions link dependent clauses to independent clauses.
We’ve already looked at some examples of coordinating conjunctions. Examples of subordinating conjunctions include:
Because | Once |
Though |
That |
---|---|---|---|
Although | Since |
Wherever |
As long as |
In case |
Supposing |
While | Even though |
There are many more subordinating conjunctions. These are just a few examples.
The coordinating conjunctions we have discussed in this article will help you create a coherent sentence. Remember the acronym FANBOYS. Check out the different examples we’ve shared to help you understand each coordinating conjunction better.
