*A comprehensive list of common grammar mistakes with clear explanations and examples to help you avoid them*
1. The Big Three: There/Their/They're
These sound identical but have completely different meanings.
· There: Refers to a place. (Hint: The word here is inside there—both refer to a place).
· Incorrect: Their going to be over they're. ❌❌
· Correct: They're going to be over there.✅✅
· Their: Shows possession (something belongs to them).
· Incorrect: The students left there books in the classroom.❌❌
· Correct: The students left their books in the classroom.✅✅
· They're: A contraction of they are.
· Incorrect: There going to be late for there own party.❌
· Correct: They're going to be late for their own party.✅
---
2. It's vs. Its
· It's: Only ever a contraction of it is or it has.
· Incorrect: The company changed it's policy.❌
· Correct: The company changed its policy✅. (The policy belongs to it, the company).
· Correct: It's been a long day. (It has been...)✅
· Its: A possessive pronoun, showing that something belongs to "it." No apostrophe is needed for possession here, just like with his, hers, yours, theirs.
Trick: If you can replace it's with it is or it has, you're using it correctly. If you're showing ownership, use its.
---
3. Your vs. You're
Another classic homophone error.
· Your: A possessive pronoun, showing something belongs to you.
· Incorrect: Is this you're jacket?❌
· Correct: Is this your jacket?✅
· You're: A contraction of you are.
· Incorrect: Your going to love this movie.❌
· Correct: You're going to love this movie.✅
Trick: Try replacing you're with you are. If it fits, you've used it correctly.
---
4. Subject-Verb Agreement
The verb must agree in number (singular/plural) with its subject.
· Incorrect: The list of items are on the desk❌. (The subject is the singular "list," not "items.")
· Correct: The list of items is on the desk.✅
· Incorrect: She and her friend likes to travel❌. (The compound subject "She and her friend" is plural).
· Correct: She and her friend like to travel.✅
---
5. Misplaced and Dangling Modifiers
A modifier (a word or phrase that describes something) should be placed next to the thing it modifies.
· Misplaced: I nearly ate the whole pizza. ❌
(This implies you almost ate it, but didn't).
· Correct: I ate nearly the whole pizza✅. (You did eat, and you ate almost all of it).
· Dangling:
Walking into the room, the light was bright. (Was the light walking? No.)
· Correct: Walking into the room, I noticed the light was bright. (The person who was walking is now the subject).
---
6. Then vs. Than
· Then: Refers to time (next, at that time).
· We went to the store, and then we went home.
· Than: Used for comparisons.
· She is taller than I am.
· I would rather read than watch TV.
---
7. Affect vs. Effect
This is tricky, but a good rule of thumb works 95% of the time.
· Affect: Usually a verb meaning "to influence."
· The bad weather will affect our travel plans.
· Effect: Usually a noun meaning "the result."
· The bad weather had a negative effect on our travel plans.
Trick: If you can put "the" in front of it, you probably need the noun effect (the effect). If you're describing the action of influencing, use the verb affect.
---
8. Apostrophe Catastrophes
Apostrophes are for contractions and possession, not for making words plural.
· Possession Correct: The dog's bowl. (One dog). The dogs' bowl. (Multiple dogs).
· Plural Incorrect:
I bought two apple's.❌
· Plural Correct: I bought two apples.
· Incorrect (common on signs):
Fresh berry's for sale! Open on Sunday's.❌❌
· Correct: Fresh berries for sale! Open on Sundays.
---
9. Could Of, Should Of, Would Of
This is always wrong. It's a mistake based on how we speak the correct form:
· Incorrect: I should of gone to the party.❌
· Correct: I should have gone to the party✅. (The contraction is should've, which sounds like "should of").
Always use could have, ✅should have, ✅would have.✅✅✅
---
10. Me vs. I
Knowing when to use "me" or "I" is a common struggle.
· The rule: Remove the other person from the sentence to see which pronoun sounds right.
· Incorrect: She gave the tickets to my friend and I.❌❌
· Test: "She gave the tickets to I." Sounds wrong. So it should be...
· Correct: She gave the tickets to my friend and me.✅
· Incorrect: Me and John are going to the game.✅
· Test: "Me is going to the game." Sounds wrong. So it should be...
· Correct: John and I are going to the game.✅
Pro Tip: It's polite to put the other person first ("my friend and me," "John and I").

Quick-Fire Round: Other Common Errors
· Loose vs. Lose:
· Loose (adj.): Not tight. (Your pants are loose).
· Lose (v.): To misplace or not win. (Don't lose your keys).
· Who's vs. Whose:
· Who's: Contraction of who is.
· Whose: Possessive pronoun (Whose book is this?).
· Fewer vs. Less:
· Fewer: For things you can count individually. (Fewer apples, fewer people).
· Less: For things you can't count (mass nouns). (Less water, less stress).
· Everyday vs. Every day:
· Everyday (adj.): Normal, commonplace. (These are my everyday shoes).
· Every day (adv.): Each day. (I go for a walk every day).
The best way to avoid these mistakes is to read often and practice writing. When in doubt, look it up!
