Grammar Mistakes I Make All The Time And How To Fix Them

Grammar Mistakes blog

Share Article

Even though I enjoy writing quite a bit, I still have a long way to go when it comes to my grammar. It is partially because I found my love for writing much later in life and partially because I write so fast that I am often not paying attention to the details.

Even as you read through this blog post, I am sure a trained eye would find at least a dozen little mistakes and errors that need fixing. I have mostly realized that I will never be perfect, but I am also trying to improve my skills every day just like you.

We all make mistakes. I want to show you that those mistakes or perceived flaws in your skillset are holding you back from achieving accurate content. So here I am, writing a blog post probably filled with grammatical mistakes about all the grammatical mistakes I make…

1. Quotation Marks at the End of Sentences

3 ways to use quotation marks

I have never understood this and probably do it wrong on a REGULAR basis. Quotations throughout sentence structure have some very unique rules.

Take this as an example:

Then she asked, “What are we having for lunch today?” I didn’t have an answer.

This is grammatically correct.

But this is what I want to do:

Then she asked, “What are we having for lunch today?”. I didn’t have an answer.

I want to put that second period in there so badly and it hurts my heart that I can’t. Why would I end that thought on a question mark? This makes it seem like an incomplete sentence… 

This is just one of what feels like thousands of rules regarding quotation marks and punctuation that always trip me up. If you struggle with this too, you can find all the answers to those questions here.

2. When-do-you-hyphenate

When I first started content writing, a person I worked with had to sit me down to have a conversation about hyphens. It wasn’t that I was using them wrong, I just wasn’t using them at all and apparently, that’s a “no-no!”

The rule of thumb (nailed it) she taught me that I remember to this day is to hyphenate words when an adjective (normally preceding a noun) is compound (i.e. two or more words). Hyphens are also used in compound nouns to lessen confusion.

Here are two examples of the same word used in two different grammatical contexts:

We visited a Korean-American supermarket.
(“Korean-American” is a compound adjective that describes the noun “supermarket.”)

There are many Korean-Americans in Los Angeles.
(“Korean-American” in this case refers to people, making it a compound noun).

Although I am still far from perfect, I have improved at using hyphens in my daily writing. Here are more rules about hyphens to help.

3. That

Using that is less about grammar and more about the flow of writing. Have you ever realized how many times you type the word “that” when it isn’t necessary? I never noticed until someone proofreading for me mentioned it.

Here is what I mean:


“It’s one of those things that people don’t realize”


“It’s one of those things people don’t realize”

See? Sometimes “that” is just a filler word adding no value to the sentence. I always have to go back after I write something and remove the “thats”. Your writing will flow SO MUCH BETTER!

4. Than & Then

Than vs then graphic

“Than” is used for comparison, and “then” is used to indicate time.


“I said pepperoni pizza is better than plain cheese pizza, then you agreed.”

“Than” is comparing pepperoni and cheese pizza. “Then” indicates a sequence of events in time. In other words, first I mentioned the pizza comparison, THEN “you” agreed.

Bonus trick to remember: Time has an “e” and so does “then.”

Here are some other ways to improve your writing:

  1. Use Grammarly — the free browser extension that helps check over your work. It helps with grammar mistakes, word choice, and sentence flow. As you may have noticed, they also write easy-to-follow blog posts about all sorts of grammar rules (Did you see that hyphenated adjective?!).
  2. Proofread your work. To proofread your work, take breaks and come back to your writing later. You can also set your writing aside for a few days and come back to it with a fresh set of eyes. Additionally, have other people proofread for you.
  3. Read your work aloud to make sure your sentences make sense. If you find yourself fumbling or sounding awkward, that’s how it will read. It’s a great way to improve the tone and sound of whatever you are writing. When in doubt, re-read it aloud!

Practice makes perfect whether you are a writing novice or a seasoned wordsmith. Keep writing and gaining experience, and your grammar and skills will improve.
