Linking function of the colon발음듣기

[Voiceover] Hello grammarians. In this video I'm going to tell you about a piece of punctuation called the colon.발음듣기

The colon is these two little dots right here, one stacked on top of the other.발음듣기

And it has quite a few functions, just like a lot of other pieces of punctuation.발음듣기

The idea of this linking function is that the colon can link an independent or dependent clause with another independent or dependent clause, or a phrase, or a word when there's a strong connection between the two things that it's linking.발음듣기

So if I want to tell someone what I think about two movies about animals, I could say: Both movies are great, but Sky Pal has one thing that makes it better: dogs that play sports.발음듣기

This is one sentence with two parts that are linked with this colon.발음듣기

So the first part says, both movies are great, but Sky Pal has one things that makes it better.발음듣기

And that could stand alone as a sentence, but it doesn't tell us what that one thing is.발음듣기

So the colon comes in and tells us, I'm about to tell you what that thing is, dogs that play sports.발음듣기

So in this case the colon just sort of serves as a connection between the purple part of the sentence and the yellow part of the sentence.발음듣기

Another example is something like: Going skydiving made me face one of my greatest fears: parachutes.발음듣기

Right, again this colon is sort of linking these two parts of the sentence where one answers an unanswered question from the first part.발음듣기

Like, what is this greatest fear?발음듣기

Well, it's parachutes.발음듣기

The colon is here to link between this whole independent clause and the word parachutes.발음듣기

I could just as well say going skydiving made me face one of my greatest fears.발음듣기

That's a perfectly fine sentence.발음듣기

But without a colon linking to what that fear is, that sentence just kind of leaves us wondering.발음듣기

So another sort of subset of the colon's ability to link things is that it can introduce things.발음듣기

One thing that the colon can introduce is a list.발음듣기

I could say: We needed to find three more items on the scavenger hunt: a four-leaf clover, a cauldron, and an abandoned ship.발음듣기

The second thing a colon can introduce is an item.발음듣기

If I'm talking about the other day when I had a weird legume craving, I could say: I only wanted one thing from the grocery store: peanuts.발음듣기

Lastly, a colon can introduce a quote.발음듣기

My friend Liz says it best: "Never open a jar of pickles you can't close."발음듣기

I'm not really sure what that means, but she does say it best.발음듣기

So, as you can see, like it was in the first couple of example sentences, there's kind of information missing from the first parts of all three of these sentences.발음듣기

We needed to find three more items on the scavenger hunt.발음듣기

Well, what did you need to find?발음듣기

Or, I only wanted one thing from the grocery store.발음듣기

What did you want?발음듣기

Or, my friend Liz says it best.발음듣기

Well, what does she say?발음듣기

That's were the colon comes in, to introduce that missing information.발음듣기

So there's one final case of the linking function of the colon that I want to get into in this video.발음듣기

If you remember from the beginning of the video, I said that colons can introduce an independent clause to another independent clause sometimes.발음듣기

That's pretty rare.발음듣기

Usually that's the job of a comma and a conjunction, or maybe a semicolon.발음듣기

But, as always, it's still important for you to know even the things that don't happen all that often.발음듣기

Something like, remember to take off your sunglasses when you drive through a tunnel: you can't see when it's that dark.발음듣기

The colon in this example shows that, you can't see when it's that dark is an explanation of why you need to take off your sunglasses.발음듣기

This is one of the two types of sentences where it makes sense to have a colon between two parts of the sentence that could stand on their own as individual sentences.발음듣기

So we can say, one, the second part explains the first part.발음듣기

The other case is when the second part of the sentence is emphasized.발음듣기

So this would be something like, I drank way too much soda: I'm never going to fall asleep!발음듣기

These are two independent clauses that could be their own sentences, but they're closely related enough that it makes sense to have them connected as one.발음듣기

So the colon links them together.발음듣기

And the second part is emphasized, right?발음듣기

That's the focus of the sentence.발음듣기

I'm never going to fall asleep!발음듣기

So in these two sentences we can see that the colon can connect two parts that can stand alone as their own sentences, right?발음듣기

Whether it's two independent clauses, like in the second sentence, or an independent clause that's technically connected to a dependent clause but can stand alone.발음듣기

Now okay, this usage is really uncommon.발음듣기

I really want to stress that.발음듣기

Usually when we're uniting two independent clauses, or at least two parts of a sentence that can stand on their own as individual sentences, we're gonna use a comma and a conjunction or a semicolon.발음듣기

But in the case that the second clause, or the second part of the sentence is emphasized or explaining the first clause, then you'll want to use a colon.발음듣기

Just keep that in mind.발음듣기

Usually this independent to independent clause linking happens with a semicolon and not a colon.발음듣기

But regardless, this is important to know.발음듣기

It's possible in these specific cases.발음듣기

What's most important for you to take away is that the colon can link things and introduce things as part of its many functions.발음듣기

And that's the linking function of the colon.발음듣기

We've got independent clauses, dependent clauses, phrases, words, and introductions for lists, and items, and quotes.발음듣기
