Common Grammar Mistakes to Avoid
Improve your writing skills by learning about these frequent errors that our free grammar and punctuation checker catches automatically.
"Your" is a possessive adjective (your book, your idea), while "you're" is a contraction of "you are." This is one of the most common mistakes in English writing that our spell checker catches instantly.
Incorrect: Your going to love this movie.
Correct: You're going to love this movie.
These three words sound the same but have completely different meanings. Our contextual grammar checker detects misuse instantly:
- There refers to a place (over there, there is)
- Their shows possession (their house, their idea)
- They're is a contraction of "they are"
Incorrect: Their going to put they're bags over there.
Correct: They're going to put their bags over there.
Similar to your/you're, "its" is possessive (the dog wagged its tail), while "it's" is a contraction of "it is" or "it has." Our grammar checker detects this common error instantly.
Incorrect: Its important to check it's spelling.
Correct: It's important to check its spelling.
A comma splice occurs when two independent clauses are joined by just a comma. You should use a semicolon, period, or conjunction instead. Our sentence structure analyzer catches these automatically and suggests the best fix.
Incorrect: I love grammar checkers, they help improve my writing.
Correct: I love grammar checkers because they help improve my writing.
The verb must agree with its subject in number (singular/plural). This gets tricky with collective nouns, compound subjects, and indefinite pronouns. Our advanced grammar checker handles these complex cases with ease.
Incorrect: The list of items are on the table.
Correct: The list of items is on the table.
Passive voice makes writing weak, indirect, and less engaging. Active voice is clearer, more direct, and more persuasive. Our style checker detects passive voice constructions and suggests powerful active alternatives.
Passive: The ball was thrown by John.
Active: John threw the ball.
"Affect" is usually a verb meaning to influence, while "effect" is usually a noun meaning result. Our vocabulary enhancer catches these misuses and suggests the correct word based on context.
Incorrect: The weather will effect our plans.
Correct: The weather will affect our plans.
"Then" refers to time or sequence, while "than" is used for comparisons. This is a common typing error that our spell checker catches immediately.
Incorrect: She is taller then her brother.
Correct: She is taller than her brother.
