Ten Common Punctuation Mistakes You Need to Avoid Making
Accuracy is vital in producing good writing, but what about common punctuation mistakes?
Basic grammar and spelling mistakes weaken any text, so you always need to correct them.
However, it is easy to overlook the most common punctuation mistakes if you are not careful.
Sometimes laziness can create punctuation errors, so you need to check carefully when it comes time for proofreading.
Ten common punctuation mistakes
It would be easy to write a much longer list here. But I’ll restrict my list of the ten most common punctuation errors.
It’s easy to learn how to spot and correct all these punctuation mistakes.
1. No commas
We all tend to write sentences as we would speak. But if a sentence is quite long, it is almost certain that it will need a comma or two to divide specific phrases correctly.
Without adding commas, you will almost certainly create run-on sentences. For example, the following sentence is incorrect.
I went to the beach yesterday afternoon but it was so hot I left quite early.
It requires a comma before but.
I went to the beach yesterday afternoon, but it was so hot I left quite early.
Never make the mistake of thinking that a comma is where you would take a breath when speaking.
There are defined comma rules in writing that you need to follow.
2. Overuse of commas
Just as important as forgetting to use commas is to add too many.
Unnecessary commas can create comma splices and interrupt the flow of a text.
Sometimes it’s much easier to end a sentence and start a new one. Here is an exaggerated example of how to make this mistake.
I was at the beach yesterday, but it was so hot, I decided to go home, but before that, I popped into the store, then I ran into a friend I hadn’t seen in years, so it was a busy day.
The sentence is very hard to read and quite confusing.
The sentence in the example above needs to be broken into complete sentences.
I was at the beach yesterday, but it was so hot. So I decided to go home. But before that, I popped into the store and ran into a friend I hadn’t seen in years. So it was a busy day.
3. Commas in quotation marks
This is such a common mistake in dialogue punctuation.
Any punctuation mark you use in your dialogue should be placed inside the closing quote.
“I want a burger,” she said, “but leave out the lettuce!”
Notice that the closing quotation marks are after her sentence-ending comma and punctuation mark.
There are a lot of punctuation variations for dialogue, so you should check a good style guide if you need help.
4. It’s and Its
This common punctuation mistake is often a typo, and most writers know the difference.
It is an easy one to correct as long as you know what it’s and its means.
It’s is a subject and verb contraction for it is or it has.
Its is a possessive pronoun that we use when referring to something belonging to something.
It’s a simple rule you probably learned in high school. But when you are writing in a hurry, it is still an easy mistake to make.
Just make sure you proofread carefully for this error.
5. Exclamation points
Yes, sometimes people can shout louder than others, but that is no reason to use more than one exclamation mark in writing.
You see it a lot today on social media and in blog posts.
But using too many makes me really so upset!!!!!!!!!
The message is just the same with one instead of nine!
Unless you are writing a personal message to a friend, go easy on them in your fiction or content writing.
Okay, emoticons are cute. But they don’t necessarily form part of the English language register.
Obviously, clever people created them and continue to come up with more on so many apps. But they are only appropriate for personal chats.
We had such a great time at the movies last night -:)
Never use them in article writing or perhaps a college essay.
Reserve them for your best friend. And anyway, emoticons are not punctuation.
7. Emphasis quotation marks
Some writers have the habit of placing double quotation marks around words when they want to add emphasis or insinuate sarcasm.
In good writing, you never need to use quotation marks for emphasis.
They behaved so “badly” at the party. Poor
I couldn’t believe how badly behaved they were at the party. Better
They were out of control at the party. Better
If you want to add emotion to a word, use more words.
We use possessive apostrophes when we indicate that something belongs to the subject. It can be a person or an object.
However, there is no apostrophe when you are referring to pluralized nouns.
Here are some examples.
My parent’s love to visit over the holidays. Incorrect. This refers to two people and not to possession.
My parents love to visit over the holidays. Correct. It is plural.
My brother’s girlfriend is coming over. Correct. The girlfriend belongs (grammatically) to the brother.
Always decide if the S indicates singular or plural or if it means to belong to someone or something.
There are many hyphenated words as well as words that are separated by en dashes.
There is also the em dash.
Dashes are extremely versatile punctuation marks. You can use them for a variety of reasons, but you should check the rules.
You can also use an en dash to show a range in numbers or dates.
22th – 26th April
Another use is to break a sentence using an em dash.
My diet has improved and has helped—definitely for the better.
But take care that you don’t overuse dashes.
10. Question marks
All writers know how to use a question mark correctly. But there is one small trap.
A question mark is often used when asking an indirect question.
Here are some examples.
Can you take me to the shop? Direct
What time is it? Direct
If it’s no trouble, could I ask you to take me to the shop? Indirect
May I ask you what time it is? Indirect
The question mark rule for indirect questions may vary depending on which reference or style guide you follow.
Good punctuation is a must in all forms of written communication.
It brings clarity and meaning to your words.
For new writers, it can be a bit of a learning curve at first.
But if you check your writing carefully and perhaps use a good online punctuation and grammar checker to help you, you will improve.
If you can avoid these ten common punctuation mistakes in this post, you will be well on your way to writing better.

10 thoughts on “Ten Common Punctuation Mistakes You Need to Avoid Making”
Sorry, but the correct punctuation here is My parents’ home etc … parents is a plural noun and their home is a possessive. Trust me on this.
Ironically, this article would have been served by an extra proof reading as some segments are poorly written.
“Even though emoticons are cute, they don’t necessarily for part of the English language. ” Form part, maybe?
The thing is that the above example, well as the other things I found in the text can happen to us all (and no doubt I will find tons of them in my own comment once it´s posted), but they are especially annoying in a text about the do´s and don´t´s in writing.
Thank you for noticing a missing letter. It has been fixed.
Use “them” and not “it” when items are plural. “Grammar and spelling mistakes are never accepted, especially if you can easily avoid them.”
Also, how do you tell someone who speaks in run-on sentences where to put a period? It’s something we hear all the time, even with professional broadcasters; people talk as if their sentence is an endless question. Terrible.
You can have apostrophes with plurals, if the plural is possessive. Just make sure you put the apostrophe after the “s”.
For example: “This is my parents’ house”. (i.e. I have two parents, and this house belongs to both of them). If you’d not included the apostrophe, this sentence wouldn’t make sense.
Always check with a plural whether its just a plain plural, or whether it takes a possessive apostrophe.
“An en dash is used to show a range, with NO spaces. If an en dash isn’t available, I prefer a hyphen to an em dash.”
Correct. The writer of this article has lumped dashes in as one thing, but there are distinct uses for the en dash, the em dash and the hyphen. You use an em dash for a break in a sentence.
In the U.S., commas and periods go inside quotation marks. A question mark or exclamation point go inside quotation marks IF it’s part of the quote.
An en dash is used to show a range, with NO spaces. If an en dash isn’t available, I prefer a hyphen to an em dash.
Was this article written as an April 4 joke?
Commas have more rules than just shoving one in where ever you think a pause should be. Read the Penguin Guide to Punctuation. A comma can change the whole meaning of a sentence.
8. Unnecessary apostrophes
Apostrophes are used when referring to an individual. Be it a person or an object.
When you are referring to multiple parties, you do not need the apostrophe.
My parent’s love to visit over the holidays.
(That is not a logical illustration; it is a plural not a possessive)
A logical illustration would be
My parent’s home was always filled with love during the holidays. OR
My parents home was always filled with love during the holidays.
Otherwise, I found this a useful — and unusually clearly written — article….jt
It would be better to say “My mom’s house” or My dad’s house” than “My parent’s house.” We usually don’t refer to our parents in the singular, which the phrase “My parent’s house” indicates. If you are talking about BOTH parents, it would be correct to write, “My parents’ house.”
