What is a conjunction?
A conjunction is a word that joins two or more words, phrases, or clauses.
Think of them as gluing words. They glue words, phrases, and clauses together.
If you'd like to have your friend bring music and snacks to your party, it's pretty hard to do it without a conjunction.
You could say, 'Bring music. Bring snacks.' But it's more efficient to say, 'Bring music and snacks.' And it's more polite to say, 'Please bring music and snacks.' :)
Do you see how the conjunction and glues the words music and snacks together?
Okay, read this question and then try to answer it with your eyes closed. What is a conjunction?
How did you do? Did you remember that they join words, phrases, and clauses? Let's look at a few more examples.
In all of those examples, we used the conjunction and, one of the most common conjunctions. But, of course, there are many more conjunctions out there. All conjunctions perform the same basic function (gluing things together), but there are three types of conjunctions, and you'll be learning about them next!
1. Coordinating Conjunctions
2. Subordinating Conjunctions
3. Correlative Conjunctions
See a list of these conjunctions here.
There are only seven of these.
for, and, nor, but, or, yet, so
Some people remember these with the acronym FANBOYS. They glue together sentence elements that are the same.

These conjunctions glue dependent adverb clauses to independent clauses. A dependent adverb clause is group of words with a subject and a verb that functions as a single adverb. They are introduced by subordinating conjunctions. There are many subordinating conjunctions. (Here's a way to help you remember them.) Here are a few. (See more on the list of conjunctions page.)
unless, whenever, since, because, if
Subordinating Conjunctions
unless you are allergic
whenever I see your cat
since you are coming
Those are not complete sentences. They all have subjects (you, I, you) and verbs (are, see, are coming), but since they can't stand alone as complete thoughts, they're subordinate clauses.
An independent clause is also a group of words with a subject and a verb. But, unlike a subordinate clause, an independent clause can stand alone.
Independent Clauses
I will bring my cat.
I sneeze.
I won't bring my cat.
These are all complete sentences. They all have subjects (I), verbs (will bring, sneeze, won't bring), and they can stand alone. Subordinating conjunctions let us join subordinate adverb clauses with independent clauses.
I will bring my cat unless you are allergic.
Whenever I see your cat, I sneeze.
Since you are coming, I won't bring my cat.
My mom smiled when I made dinner.

Correlative conjunctions are used in pairs (either...or, both...and), but they have the same function as coordinating conjunctions. That means that they join things that are the same.
Both David and I are allergic to cats.
Either Mom or Dad will pick you up.
He is both intelligent and good-natured.
Chocolate and almonds taste delicious.
