Even the most experienced English speakers and writers make grammar mistakes from time to time. However, knowing the most common errors and how to fix them can significantly improve your writing and speaking skills. In this lesson, we’ll explore 10 common grammar mistakes, explain why they’re wrong, and provide tips to avoid them. Let’s get started!
Grammar mistakes can make your writing unclear, confusing, or even incorrect. By learning the most common errors, you can avoid them and communicate more effectively. This lesson will help you identify and correct these mistakes with ease.
10 Common Grammar Mistakes
1. Subject-Verb Agreement
Mistake: The verb doesn’t agree with the subject in number (singular or plural).
- Incorrect: She like apples.
- Correct: She likes apples.
- Why It’s Wrong: The subject (she) is singular, so the verb must also be singular (likes).
2. Misusing Apostrophes
Mistake: Using apostrophes incorrectly in plurals or possessive forms.
- Incorrect: The cat’s are cute.
- Correct: The cats are cute.
- Why It’s Wrong: Apostrophes are used for possession (e.g., the cat’s tail) or contractions (e.g., it’s), not for plurals.
3. Double Negatives
Mistake: Using two negative words in the same sentence.
- Incorrect: I don’t have no money.
- Correct: I don’t have any money.
- Why It’s Wrong: Double negatives cancel each other out, creating a positive meaning, which is confusing.
4. Confusing “Your” and “You’re”
Mistake: Using “your” (possessive) instead of “you’re” (contraction of “you are”).
- Incorrect: Your going to love this movie.
- Correct: You’re going to love this movie.
- Why It’s Wrong: “Your” shows possession (e.g., your book), while “you’re” means “you are.”
5. Confusing “Their,” “There,” and “They’re”
Mistake: Using these words interchangeably.
- Incorrect: Their going to the park.
- Correct: They’re going to the park.
- Why It’s Wrong:
- Their = possession (e.g., their car).
- There = place (e.g., over there).
- They’re = contraction of “they are.”
6. Run-On Sentences
Mistake: Joining two independent clauses without proper punctuation or conjunctions.
- Incorrect: I went to the store I bought milk.
- Correct: I went to the store, and I bought milk.
- Why It’s Wrong: Run-on sentences are hard to read and confusing. Use a comma and conjunction (e.g., and, but) or split into two sentences.
7. Misplaced Modifiers
Mistake: Placing modifiers too far from the words they describe.
- Incorrect: She almost drove the car for six hours.
- Correct: She drove the car for almost six hours.
- Why It’s Wrong: Misplaced modifiers change the meaning of the sentence.
8. Confusing “Its” and “It’s”
Mistake: Using “it’s” (contraction of “it is”) instead of “its” (possessive).
- Incorrect: The dog wagged it’s tail.
- Correct: The dog wagged its tail.
- Why It’s Wrong: “It’s” means “it is,” while “its” shows possession.
9. Using “Me” vs. “I” Incorrectly
Mistake: Using “me” instead of “I” (or vice versa) in compound subjects or objects.
- Incorrect: Me and John went to the store.
- Correct: John and I went to the store.
- Why It’s Wrong: Use “I” as the subject and “me” as the object.
- Tip: Remove the other person to check: Me went to the store → Incorrect.
10. Overusing Passive Voice
Mistake: Using passive voice when active voice is clearer and more direct.
- Incorrect: The ball was thrown by John.
- Correct: John threw the ball.
- Why It’s Wrong: Passive voice can make sentences wordy and less engaging.
