Pity the Poor Semicolon!

Have you noticed how many times semicolons get dragged into the wrong place in a sentence?

Too often, one is used instead of a comma or colon, either of which would be happy to take its place! Too many writers have no idea what to do with it, and I hope this post will help.

I teach a three-hour corporate workshop called “Brush Up on Your American Grammar Skills,” and I discuss the most-common uses of the major punctuation marks. The workshop is intended for business professionals, whose goal is usually to communicate a message clearly. And I believe in the KISS principle — my version of it anyway.

Here are the three — yes, only three — basic rules in the American grammar system for using a semicolon in business writing. If you are writing a thesis of some kind, you might find another rule or two, but first — let’s all master these three.

1. Compound Sentences: Use a semicolon to join two independent clauses (simple sentences) together. Each sentence could stand on its own (each has a subject and predicate and is a finished thought), but you choose to join them because they work better as a complete thought. Simply replace the period of the first sentence with a semicolon, as shown below, and you’re good to go!

As separate sentences:

Mary had a sandwich for lunch. John opted for a burger.
John’s running late. Susan will fill in for him until he arrives.

With the semicolon used correctly:

Mary had a sandwich for lunch; John opted for a burger.
John’s running late; Susan will fill in for him until he arrives.

You could also connect them by using a comma, and one of the seven coordinating conjunctions (and, but, for, nor, or, so, yet).

Mary had a sandwich for lunch, but John opted for a burger.
John’s running late, so Susan will fill in for him until he arrives.

NOTE: There is NO requirement to join the two independent sentences, but many writers realize that always writing short sentences makes them look as though they never left third grade, which is hardly the impression most writers want to make.

2.  Transitional Expressions: If you link independent clauses with terms such as for example, however, moreover, namely, nevertheless, or therefore, replace the period of the first sentence with a semicolon. Again, you may always choose to keep the sentences separate.

We’ll go to the movie. However, we’ll wait until the 9 p.m. show.
We’ll go to the movie; however, we’ll wait until the 9 p.m. show.

She’s fully qualified for the job. For example, she’s had ten years’ experience.
She’s fully qualified for the job; for example, she’s had ten years’ experience.

3. Items in a Complex Series: Items in a complex series contain required internal commas, so we use semicolons to separate the sections. Think of the semicolon as an “internal traffic cop”; it’s not an end mark of punctuation, but within a sentence of this type it indicates a section is finished.

In the example below, it’s especially difficult to figure out who is who when the occupations and names are written as shown! Which name goes with which occupation?

Who is who?

Please invite the President, Ann Murphy, the Executive Vice President, Sam Smith, the Director of Investor Relations, and Penny Smith, the Chief Financial Officer.

If you read all the way to the end, the sequence becomes clear: the name comes before the occupation in the sentence. That means that “President” has no name attached to it — in this sentence.

Any easier?

Please invite the President; Ann Murphy, the Executive Vice President; Sam Smith, the Director of Investor Relations; and Penny Smith, the Chief Financial Officer.

Using the semicolon after President is intended to show that the name following it does not belong to it. Will that work with every reader? Nope. Nothing works with everyone, but here we’re trying to make it easier to understand for most readers. Again, I like bullet points with lists like this, although without the President’s name, it’s still a terrible sentence.

Maybe even easier?

Please invite the President; the Executive Vice President, Ann Murphy; the Director of Investor Relations, Sam Smith; and the Chief Financial Officer, Penny Smith.

Now, in the real world, we’d find out that President’s name, right? So, I’m just showing this sentence for illustrative purposes.

One more example:

The firm has offices in Boston, Mass.; Cranston, R.I.; Atlanta, Ga.; and San Diego, Calif.

The last example again shows required commas (between the cities and the states) but the state name ends a specific section of the sentence, thus requiring a semicolon after it.

Here are a few common NO-NOs:

Mary said to John; “Are we going out tonight?” (Use a comma.)

John and Mary went to the show; but they arrived late. (Use a comma.)

Dear John; (Use a comma.)

Dear Mr. Smith; (Use a colon.)

Although they tried to plan; they failed. (Use a comma.)

I need just three things to finish; scissors, glue, and tape. (Use a colon.)

In the end, if we can remember that semicolons have a very restricted use, we might writer clearer prose. And we’d make our grammar teachers very, very happy.

    • Yes, it is, Andrew, although written by a Brit, so the English is a little different for Americans! But for a great read and some fun, yes.

    • I have always struggled with grammar. I left school at 16 to play music. I gained a lot and I missed a lot. Thank goodness for my wife’s editing skills

    • Heck, Larry, I stayed in school till I graduated and STILL missed a lot! How can anyone know at 18 or 20 or even 30 what’s really important? Good for you, though!
