Colon Uses and Implementing Proper Punctuation

Punctuation holds a lot of importance in the wonderful world of writing. It can help readers parse your text more efficiently, allow you to segment information more thoroughly, and provide valuable context in certain places. However, punctuation isn’t limited to periods and commas. Another important form of punctuation that you should learn about is the colon. We’ll be providing you with an overview of colon uses, as well as describe what the symbol is. First things first, let’s discuss how you can use it in writing.

What are colon uses in writing?

There are three main colon uses in writing, all of which have to do with introductions. Simply put, you can introduce lists, explanations, and quotations by preceding them with a colon. Here are some examples:


I only like three things: cooking, reading, and basketball.


I’m only allergic to one thing: peanuts.


The president’s statement was the same as before: “We need to improve the economy.”

In all of these cases, colons come after a sentence classified as an independent clause.

What does the colon symbolize in writing? What is the meaning behind it?

You can learn a lot about the purpose behind the colon by understanding its position after an independent clause. Most forms of punctuation that follow an independent clause of some kind tend to serve a transitory function, which is to say that they indicate a pause or separation between two independent clauses. That’s why you should add them between an introductory sentence and a list, explanation, or quotation. It creates a pause followed by an expansion of the previous statement.

Where is the colon punctuation mark on the American keyboard?

If you were to take a look at the right hand side of your keyboard, you’ll see a button between the L and “ keys that features a colon and semicolon. Pressing this key while holding down SHIFT creates a colon, whereas pressing it without holding down shift creates a semicolon.

What does the colon punctuation symbol look like?

A colon punctuation symbol looks like two dots placed on top of each other like this “:”.

When is it appropriate to use a colon when writing?

If you’re about to introduce a separate independent clause or article, it’s appropriate to separate it from the previous independent clause with a colon. You can also refer to the preceding clause as an “introductory clause”. This goes for lists, quotations, and examples or explanations. However, there are other uses for the colon as well. You can use them to introduce a subtitle like in this example:

The Lord of the Rings: The Fellowship of the Ring

You can also use them to separate hours and minutes while telling the time, like in 10:30. Finally, colons separate two values in a ratio, like 2:3. While this might not be relevant to most forms of writing, it’s important to know about.

How to know when to use colon?

To learn colon uses, you must understand its primary functions. It’s a way to separate an introductory clause from a list, quotation, explanation, or an example. Pay attention to how we’ve introduced examples previously – they’re always preceded by a colon, which should give you some context clues for using them in your writing.

How to know when to use colon vs semicolon?

Colons and semicolons might look similar, but they have different uses. As we’ve said previously, you can use colons to introduce lists, explanations, examples, or quotations. You can also separate titles from subtitles with colons, as well as minutes and hours while telling the time, and two values in a ratio.

However, semicolons serve a distinct function. They don’t separate two clauses, they join them up. If you have two related independent sentences, you can link them with a semicolon, or you can make complex lists easier to parse with this punctuation mark.

Should a colon or semicolon be used in lists?

You can use both colons as well as semicolons in lists. However, if we were to focus on starting lists, colons are the correct choice, whereas both can separate independent clauses within the list. It depends on whether the clauses are related or if one is an introductory clause.

How do colons affect the punctuation of a sentence?

Since colons act as clause separators, you shouldn’t use any punctuation directly before or after them. Here’s an example of an incorrect use of a colon:

I want three things for my birthday,: balloons, cake, and new clothes.

The comma is unnecessary in this example, so you should avoid making mistakes like these.

What are the colon uses according to Chicago, APA, and MLA style guides?

All three major style guides refer to colons in order to help writers use them effectively. According to the Chicago Manual of Style, colons can introduce lists, examples, explanations, and quotations. It’s the most prescriptive style guide of all, so if you base your writing on it, be sure to use it only in the aforementioned contexts.

As for the APA and MLA style guides, they’re not quite so rigid regarding how you use punctuation. Even so, you should avoid using them for anything other than separating an introductory clause from a subsequent clause.

How to know the correct colon uses in a sentence?

A good rule of thumb to follow is to check and see if you’re using colons in the correct places. Does your sentence consist of an independent clause? Is this independent clause setting up a list of items, or perhaps explaining the meaning behind the preceding sentence, or introducing a direct quote? If the answer to all of these questions is yes, you can use a colon. If not, consider double checking or using some other form of punctuation.
