Whether it be in person, over text, or on Facebook, we've all witnessed the simple grammar mistakes that some people just can't seem to figure out. Although they can be pretty fun to correct, I figured it was time for most of us to get a little refresher on these eight most common grammar mistakes.

1. Its vs. It's

Its is possessive of whatever follows the phrase, whereas it’s means “it is." Ex. It’s extremely fun to point out grammar mistakes. :))

2. Ok vs. Okay

This one is pretty straightforward; it’s Ok. That’s it. Okay is not even a word. No matter how many times our iPhones tell us it is.

3. Their vs. There vs. They're

My favorite mistake to correct! Their is a possessive pronoun. There refers to a place or location. They’re is a contraction of the words “they” and “are." You wouldn’t say “They’re is the bookstore,” which translates to “they are is a bookstore.” Next time you want to use their/there/they’re, say it out loud so this mistake can be avoided.

4. Your vs. You're

Your modifies nouns and shows possession. Ex. Your dog is so cute. You’re is a contraction combining both “you” and “are”. Ex. You’re about to run a red light. This one is really really important, so don’t forget it!!!

5. Then vs. Than

It’s pretty easy to remember this one. Then refers to time. Than is used to compare things. Easy as pie!

6. Everyday vs. Every Day

Everyday describes a daily, recurring event. Every Day implies “each day”. Ex. "Everyday I’m shufflin’." *cue LMFAO, please.

7. Two vs. Too vs. To

What would seem like the easiest concept to grasp, appears to be the most misconstrued. Two is just a number. An adverb Too is used in the context of something being “excessive” or “a lot." To is essentially used for everything else.

8. Definitely vs. Defiantly

I’d like to thank spellcheck for this one. Although it is a tricky word for lots of people to spell, definitely is used to show certainty. Defiantly is used to show rebellion or resistance. So before you tell your mom you're, “Defiantly going to hang out with your friends” make sure you check your spelling. ;)
