Let’s talk about semicolons.
What is a Semicolon?
Punctuation is used to separate sentences, phrases, or words to further clarify a piece of writing. A semicolon, which looks like a period stacked on top of a comma, is used most commonly to join two independent clauses without using a coordinating conjunction.
Dependent and Independent Clauses
Independent clauses are clauses that can stand alone in a sentence as a complete thought. An independent clause always has a subject, a verb, and a complete thought.
An example of an independent clause would be the following sentence:
The sentence needs no more explanation; it doesn’t leave us hanging. Dependent clauses have subjects and verbs too, but they don’t have complete thoughts. For example, look at this sentence:
That is a dependent clause. It feels like it should have an ellipsis after it instead of a period, because the sentence isn’t finished. Because Bob went to the store…what? We don’t know, and that’s what makes it a dependent clause.
When you join independent clauses together, you normally have to use coordinating conjunctions. These are words that link other words, phrases, or clauses together, words like and, but, and yet.
Now that we understand what an independent clause is and what a conjunction is, let’s look back at our definition of a semicolon: punctuation used most commonly to join two independent clauses together without using a conjunction.
When to Use a Semicolon
Let’s take a look at a semicolon in action. Say you had the following two sentences:
A period is joining the two sentences, but if we used only periods as punctuation we would have only short, choppy sentences. Let’s join those two independent clauses up with a conjunction.
To join two independent clauses together with a coordinating conjunction like and or but, you also have to use a comma before the conjunction. A comma is not sufficient by itself, and neither is the conjunction by itself.
But, here enters our heroic semicolon. It acts like both the comma and the conjunction working together. While it is not grammatically correct to write “Rina came home, she ate fried chicken for dinner,” or “Rina came home and she ate fried chicken for dinner,” it is correct to write:
A semicolon, in this sense, functions as a “, and” in the sentence. Semicolons are stronger than a comma, but not as divisive as a period.
Helpful Rules to Remember
Here are some other helpful rules to remember when using semicolons:
2. Use semicolons to help with complicated lists. Sometimes you have to list things that have, within themselves, further clarifications. Semicolons can help with this. Look at the following sentence, for example:
3. Use semicolons with conjunctive adverbs. Don’t get scared off by this new phrase. Conjunctive adverbs are exactly how they sound—adverbs that sometimes act as conjunctions. Think about words like moreover, also, however, etc. If you’re using some such word to connect two independent clauses, it’s much stronger to use a semicolon beforehand than a comma.
Here’s an example.
The semicolon separates the first independent clause from the conjunctive adverb, which itself uses a comma to separate from the second independent clause.
Now that you have a firm grasp on all the good things semicolons can do, let’s go over a few things they can’t do.
2. You should never capitalize words after a semicolon. Semicolons may be a stronger form of punctuation than a comma, but they still aren’t as significant of a pause as periods are. Clauses joined by semicolons are still within the same sentence.
3. Avoid the common misconception that semicolons and colons are interchangeable. Colons have two periods stacked on top of each other and are often used to introduce or define something. They can be used to connect independent clauses with something as simple as a single noun, while semicolons can only connect two full independent clauses.
Well, that’s all for now! Thanks for watching!
Frequently Asked Questions
Q
When do you use a semicolon?
A
There are several different situations where you can use a semicolon. Perhaps the most common usage is to use semicolons to connect two independent clauses that are related to each other. Here are a couple of examples:
“The mall is my favorite place to shop; everything I need is under one roof!”
“I recognized him; however, I could not remember his name.”
Semicolons also help to make clarifications among complex series. In other words, if one of the items in a series contains a comma, semicolons are used to separate the series items. Here’s an example:
“Darius bought six apples; nine oranges, which were on sale; and a large loaf of bread.”
Q
When do you use a semicolon in a list?
A
A semicolon should be used in a list or series when the list already contains commas, and more separation between the items is needed. Here’s an example:
“The four people invited to the party are Sasha; Ricardo; Lea, Ricardo’s sister; and Tiana.”
Q
When do you use a semicolon vs. a colon?
A
Colons are used to introduce something, like an example or list. Semicolons are used to join two independent clauses or to better organize complex lists.
For example, here’s a sentence that uses a colon to introduce a list of items:
“There are three states that begin with the letter C: California, Colorado, and Connecticut.”
Here’s a sentence that uses a semicolon to join two independent clauses:
“I’ll need to find my umbrella before I leave the house; it’s supposed to rain today.”
Q
When do you use a semicolon vs a comma?
A
Semicolons and commas can both be used to join two independent clauses. In order to use a comma for this purpose, you must pair it with a coordinating conjunction (for, and, nor, but, or, yet). To use a semicolon, you can either use the semicolon on its own or pair it with a conjunctive adverb (also, besides, however, instead, meanwhile, therefore).
Here are two examples of a comma being used to join two independent clauses:
“James wandered through the forest, and he came upon a moss-covered stone.”
“I thought she turned left, but she must have turned right.”
In both examples, the comma is paired with a coordinating conjunction.
Here are two examples of a semicolon being used to join two independent clauses:
“These cookies are delicious; I would love to have the recipe!”
“Some people prefer typing notes; however, I prefer to handwrite notes.”
