A conjunction is a word that links together words and phrases.
A conjunction is the glue that joins together words, lists of words, and phrases in a sentence.
There are coordinating conjunctions, subordinating conjunctions and correlative conjunctions. Before we discuss each type, you first need to understand the differences between an independent clause and a dependent clause.
An independent clause has everything a sentence needs: a subject and a predicate. A subject is the who or what doing the action in a sentence. The predicate is the action the subject is doing.
Examples of independent clauses:
She went to school.
Subject = she; Predicate = went to school
I loaded the dishwasher.
Subject = I; Predicate = loaded the dishwasher
My sister and I bought tickets for the movies.
Subject = my sister and I; Predicate = bought tickets for the movies.
A dependent clause is missing either a subject or a predicate or both.
Examples of dependent clauses:
Went to school
Missing a subject
All of the people at the meeting
Missing a predicate
Working towards a conclusion
Missing both a subject and a predicate
Because of the refrigerator
Missing both a subject and a predicate
An independent clause could stand alone on its own as a sentence with proper punctuation. A dependent clause cannot and relies on an independent clause to help it stand. If a dependent clause is left alone and isn't attached to an independent clause to help it stand, we call that a sentence fragment.
can stand alone on its own as a complete sentence, or can be joined with another independent clause or dependent clause.
cannot stand alone on it own and must depend on an independent clause to help it stand. A dependent clause on its own is called a "sentence fragment."
work together because the independent clause is helping the dependent clause stand.
Coordinating conjunctions are what come to most people's minds when they hear the word "conjunction." They join together words, phrases, and independent clauses. With them, short and choppy sentences can be joined into fuller lines. There are seven of them, and they're easy to remember if you can just think of the acronym "FANBOYS." When a coordinating conjunction is used to join together two independent (able to stand on their own) clauses, a comma (,) is used.
For
And
Nor
But
Or
Yet
So
Examples of a coordinating conjunction joining together words:
For breakfast, would you like bacon or sausage?
I packed shorts, shirts, and shoes.
Example of a coordinating conjunction joining together phrases:
After lunch, I walked back to the building and through the front door.
Example of a coordinating conjunction + a comma joining together independent clauses:
Hockey is fun to watch on the T.V., but it's better to watch in-person. (Hockey is fun to watch is an independent clause, meaning it could be a sentence that stood on its own. So is it's better to watch in-person. A comma and the conjunction but join these two independent clauses together.)
I take a book with me on vacation, yet I never seem to turn a single page. (I take a book with me on vacation is an independent clause. So is I never seem to turn a single page. A comma plus the conjunction yet join these two independent clauses together.)
A subordinating conjunction is used to join together an independent clause and a dependent clause. The most common subordinating conjunctions are:
although
as
because
before
how
if
once
since
than
that
though
until
when
whenever
whether
while
When the dependent clause is at the beginning of the sentence, use a comma between the dependent and independent clauses.
Examples:
Once I remembered that the oven was on, I rushed into the kitchen.
Since that day, I've always wanted a little dog.
Although I don't recommend it, you can purchase all your supplies online.
When the dependent clause is at the end of the sentence, do not use a comma to separate the two clauses.
Examples:
I rushed into the kitchen once I remembered that the oven was on.
I've always wanted a little dog since that day.
You can purchase all your supplies online although I don't recommend it.
Correlative conjunctions are tag-team conjunctions. They come in pairs, and you have to use both of them in different places in a sentence to make them work. Correlative conjunctions connect two equal grammatical terms. So, if a noun follows "both," then a noun should also follow "and."
Common pairs include:
both/and
whether/or
either/or
neither/nor
not/but
not only/but also
Examples:
I want both a new bike and a new pair of shoes.
Whether we go to the beach or to the boardwalk, we're sure to have a good time.
She wanted neither his sass nor his attitude.
Not only is Oregon beautiful, but it is also peaceful.
