Examples of Colon [3 Types]

A colon has multiple uses: explaining a statement, introducing a list, introducing a quotation or excerpt, and being part of ratio, numeric terms, titles, and citations. (The previous sentence used colon to introduce a list.) In this post, we’ll cover examples of colon in sentences, categorized under its first three uses. Of the four, the first use is most common in writing and hence will be covered most extensively.

Note that, when writing a sentence using colon, colon is always preceded by a complete sentence, but what follows may or may not be a sentence.

1. Examples of colon explaining a statement

What comes after a colon explains or expands what comes before it. To get the most out of these examples, notice how this holds for each of these sentences.

1.1 Both sides of the colon are sentences

(Note that the text after colon starts with a capital letter because it’s a sentence.)

The countdown serves three purposes: One, it has a psychological effect of making me more focused; two, by counting the sessions, I get a sense of my productive time in the day; and, three, at the end of the session, I take a natural break to restore my focus. [On the right is a compound sentence.]

Infrastructure projects could be of very different sizes: a primary school building running into few thousand dollars to large infrastructure projects such as city transport running into billions of dollars.

1.3 Multiple sentences on the right side

Often, you can easily tell a noun from an adjective, but if you face challenge, you can apply this test: Put the suspected word before the subject. If it makes sense, it’s an adjective. If it doesn’t, it’s a noun.

  • At the end of the session, I take a natural break to restore my focus.

(The last sentence has also been written in subsection 1.1 as a sentence each on either side of the colon. Note that we’ve used a period in each bullet because each is a complete sentence.)
