🚩 Top 15 Common Grammar Mistakes (And How to Fix Them)

Let’s break down the most frequent offenders and how to get them right.

1. They’re / Their / There

Mistake: “Their going to the store.”
Fix: “They’re going to the store.”

• They’re = They are
• Their = Belonging to them
• There = A place or position

2. Your / You’re

Mistake: “Your awesome!”
Fix: “You’re awesome!”

• Your = Possessive (your car, your idea)
• You’re = You are

3. Its / It’s

Mistake: “The dog wagged it’s tail.”
Fix: “The dog wagged its tail.”

• Its = Possessive form of “it”
• It’s = It is

4. Then / Than

Mistake: “She’s better then me.”
Fix: “She’s better than me.”

• Then = Refers to time
• Than = Used in comparisons

5. Affect / Effect

Mistake: “The new law will effect small businesses.”
Fix: “The new law will affect small businesses.”

• Affect = Verb (to influence)
• Effect = Noun (a result)

6. Run-on Sentences

Mistake: “I love coffee I drink it every day.”
Fix: “I love coffee. I drink it every day.”

Tips: Use a period, semicolon, or conjunction (and, but, because) to separate ideas.

7. Comma Splices

Mistake: “She writes well, she edits poorly.”
Fix: “She writes well, but she edits poorly.”

Fix Options:

• Replace comma with period.
• Use a semicolon.
• Add a conjunction.

8. Sentence Fragments

Mistake: “Because I went to the store.”
Fix: “I bought snacks because I went to the store.”

Tip: A sentence needs a subject and a verb to be complete.

9. Misplaced Modifiers

Mistake: “Running quickly, the finish line was crossed.”
Fix: “Running quickly, she crossed the finish line.”

Tip: Make sure it’s clear what the modifier is describing.

10. Subject-Verb Agreement

Mistake: “The list of items are long.”
Fix: “The list of items is long.”

Tip: The verb should agree with the subject, not the object of the sentence.

11. Overusing Apostrophes

Mistake: “The Johnson’s are coming over.”
Fix: “The Johnsons are coming over.”

• Use apostrophes for possessives, not plurals.

12. Double Negatives

Mistake: “I don’t know nothing.”
Fix: “I don’t know anything.”

Tip: Two negatives cancel each other out and make your sentence confusing.

13. Confusing Me vs. I

Mistake: “Me and John went to the store.”
Fix: “John and I went to the store.”

Quick Trick: Take out the other person’s name and see if it still makes sense.

14. Who vs. Whom

Mistake: “Who did you call?”
Fix: “Whom did you call?”

• Who = subject
• Whom = object

Tip: If you can replace it with “he,” use who. If “him,” use whom.

15. Capitalization Errors

Mistake: “i went to New york city.”
Fix: “I went to New York City.”

Tip: Capitalize:

• Proper nouns (names, cities)
• The pronoun “I”
• The first word in a sentence
