Today, I will introduce you to the wonderful world of semicolons!
The semicolon is among the top misused punctuation marks and remains a mystery to most people. But no longer! Only four rules for semicolons exist – and they are easy to follow.
Here they are:
Use a semicolon to replace a period. Sometimes, you may write two complete sentences (sentences with a subject and a verb) for which a joining comma is too weak. That is, the two sentences really do belong together, but they need more emphasis than a mere comma. Alternately, in order to avoid short sentences, you may not want to use a period. Instead, you can use a semicolon.
As an example, take the following sentence:
Alzena’s limbs were still too battered to continue the journey to Fugglestone; breathing hurt her ribs, and her left leg still lay mangled from the attack by Count Osric’s dogs.
In this example, each sentence is a complete thought, but because they complement each other, I’ve put them into one sentence.
Use a semicolon before qualifying words such as “therefore,” “that is,” or “after all” when they introduce a complete sentence. Qualifying words amplify or explain the first statement. The two sentences therefore belong together, but instead of using an incorrect comma, use a semicolon. (It would also be perfectly okay to separate the two with a period.)
For example, try this:
Count Osric’s dogs mysteriously appeared whenever anyone attempted to cross his lands; therefore, some peasants claimed that they were spirits.
This example contains two complementary but complete thoughts joined by “therefore.” Thus, I separated them with semicolon.
When you are listing items in a series and one or more of the items must contain a comma, then use a semicolon to separate the items.
For example, say you are listing the names and sires of Count Osric’s dogs. The name of each dog and its sire are separated by a comma. You must, therefore, use a semicolon to sort the information out, or you’ll end up with a mess.
But the superstitious Peterkin swore that demons had sired Count Osric’s dogs and would name their fathers. He knew all of the count’s dogs – Lazarus, son of Abaddon; Uriel, son of Belial; Herne, son of Moloch.
In the above example, if I had not separated the name and parentage of each dog with a semicolon, the reader would be forced to mentally separate each unit in the sentence. Why make your readers work when a simple punctuation mark does so for them?
Separate two complete sentences joined by “or,” “and,” or “but” when the first sentence contains commas. This is not required, as you can use a simple comma, but as with the previous rule, using a semicolon can simplify the sentence for your readers.
What does this mean for Alzena and her ruined leg? Let’s see.
A pilgrimage to the holy shrine near Foulpapple, where the goddess Myrtis was said to stir the waters, would heal her destroyed leg; but how could Alzena escape the count’s guards?
Both sentences are complete thoughts, and the first sentence contains a comma. Therefore, just to sort out the clauses, I used a semicolon to introduce the second sentence.
Semicolons, as you can see, are not very mysterious at all. Just as with any other facet of grammar, it’s only a matter of knowing a few rules and applying them to use the semicolon correctly.
