The semicolon is one of the most misunderstood and misused punctuation marks; in fact, it is often mistaken for the colon (which we’ll discuss next). However, these two punctuation marks are not interchangeable. A semicolon connects two complete ideas (a complete idea has a subject and a verb) that are connected to each other. Look at this sentence for example:

Anika’s statue is presently displayed in the center of the exhibit; this location makes it a focal point and allows it to direct the flow of visitors to the museum.

The first idea tells us where Anika’s statue is, and the second idea tells us more about the location and it’s importance. Each of these ideas could be its own sentence, but by using a semicolon, the author is telling the reader that the two ideas are connected. Often, you may find yourself putting a comma in the place of the semicolon; this is incorrect. Using a comma here would create a run-on sentence. Remember: a comma can join a complete idea to other items while a semicolon needs a complete idea on either side.

The semicolon can also be used to separate items in a list when those items have internal commas. For example, say you’re listing a series of cities and their states, or you’re listing duties for a resume:

As a photographer for National Geographic, Renato had been to a lot of different places including São Paulo, Brazil; Kobe, Japan; Kyiv, Ukraine; and Barcelona, Spain.
As an engineering assistant, I had a variety of duties: participating in pressure ventilation surveys; completing daily drafting, surveying, and data compilation; and acting as a company representative during a roof-bolt pull test.

Exercise

Correct the following sentences by adding semicolons. If the sentence is correct as it is, write “correct.”

I did not notice that you were in the office I was behind the front desk all day.
Do you want turkey, spinach, and cheese roast beef, lettuce, and cheese or ham, tomato, and cheese?
Please close the blinds there is a glare on the screen.4. Unbelievably, no one was hurt in the accident.
I cannot decide if I want my room to be green, brown, and purple green, black, and brown or green, brown, and dark red.
Let’s go for a walk the air is so refreshing.
