2.2 Semicolons

Learning Objectives

  1. Identify the uses of semicolons.
  2. Properly use semicolons in sentences.

Another punctuation mark that you will encounter is the semicolon (;)A punctuation mark that indicates a pause and joins two independent clauses or separates a list when the list already requires commas.. Like most punctuation marks, the semicolon can be used in a variety of ways. The semicolon indicates a break in the flow of a sentence, but functions differently than a period or a comma. When you encounter a semicolon while reading aloud, this represents a good place to pause and take a breath.

Semicolons to Join Two Independent Clauses

Use a semicolon to combine two closely related independent clauses. Relying on a period to separate the related clauses into two shorter sentences could lead to choppy writing. Using a comma would create an awkward run-on sentence.

Correct: Be sure to wear clean, well-pressed clothes to the interview; appearances are important.

Choppy: Be sure to wear clean, well-pressed clothes to the interview. Appearances are important.

Incorrect: Be sure to wear clean, well-pressed clothes to the interview, appearances are important.

In this case, writing the independent clauses as two sentences separated by a period is correct. However, using a semicolon to combine the clauses can make your writing more interesting by creating a variety of sentence lengths and structures while preserving the flow of ideas.

Semicolons to Join Items in a List

You can also use a semicolon to join items in a list when the items in the list already require commas. Semicolons help the reader distinguish between items in the list.

Correct: The color combinations we can choose from are black, white, and grey; green, brown, and black; or red, green, and brown.

Incorrect: The color combinations we can choose from are black, white, and grey, green, brown, and black, or red, green, and brown.

By using semicolons in this sentence, the reader can easily distinguish between the three sets of colors.

Tip

Use semicolons to join two main clauses. Do not use semicolons with coordinating conjunctions such as and, or, and but.

Exercise 1

On your own sheet of paper, correct the following sentences by adding semicolons. If the sentence is correct as it is, write OK.

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

Key Takeaways

  • Use a semicolon to join two independent clauses.
  • Use a semicolon to separate items in a list when those items already require a comma.
