English grammar plays an important role in effective communication. Whether you are writing essays, emails, blog posts, or professional reports, proper grammar helps ensure your message is clear and easy to understand.
However, grammar mistakes are extremely common. Even native English speakers sometimes make errors in everyday writing. Small mistakes such as confusing similar words, misusing punctuation, or writing incomplete sentences can make writing harder to understand.
Learning to recognize and correct these mistakes is one of the best ways to improve your English skills. Many educational platforms and online resources help learners strengthen their grammar knowledge while practicing real-world writing examples. In the same way that online platforms guide users through step-by-step processes—such as accessing services through a secure account like TMT Cash Login—learning grammar becomes easier when you understand clear rules and structured guidance.
In this article, we will explore 10 common grammar mistakes in English and practical ways to fix them.
1. Subject–Verb Agreement Errors
Subject–verb agreement is one of the most important grammar rules in English. It means that the verb must match the subject in number.
A singular subject requires a singular verb, while a plural subject requires a plural verb.
Incorrect example:
She go to school every day.
Correct example:
She goes to school every day.
Another example:
Incorrect: The students is studying.
Correct: The students are studying.
To avoid this mistake:
- Identify the subject of the sentence
- Check whether the subject is singular or plural
- Make sure the verb matches the subject
2. Confusing “Their,” “There,” and “They’re”
These words are often confused because they sound the same but have different meanings.
Their – indicates possession
Example: Their classroom is on the second floor.
There – refers to a location
Example: The library is over there.
They’re – contraction of “they are”
Example: They’re preparing for their exams.
A simple trick is to replace the word with “they are.” If the sentence still makes sense, then they’re is the correct choice.
3. Mixing Up “Your” and “You’re”
Another frequent grammar mistake is confusing “your” and “you’re.”
Your shows possession.
Example: Your assignment is due tomorrow.
You’re is a contraction of “you are.”
Example: You’re doing a great job improving your grammar.
Incorrect example:
Your going to enjoy this lesson.
Correct example:
You’re going to enjoy this lesson.
4. Run-On Sentences
Run-on sentences happen when two independent clauses are joined without proper punctuation or conjunctions.
Incorrect example:
I enjoy learning English I practice writing every day.
Correct examples:
I enjoy learning English. I practice writing every day.
or
I enjoy learning English, and I practice writing every day.
Using punctuation correctly helps improve readability and sentence clarity.
5. Sentence Fragments
A sentence fragment is an incomplete sentence that does not express a complete thought.
Incorrect example:
Because I forgot my notebook.
Correct example:
I couldn’t complete the assignment because I forgot my notebook.
A complete sentence must include:
- a subject
- a verb
- a complete idea
Avoiding sentence fragments is important for clear communication.
6. Incorrect Use of Apostrophes
Apostrophes are commonly used in English for possession and contractions.
Correct examples:
The teacher’s book is on the desk.
It’s a great day to practice writing.
A common mistake occurs with its and it’s.
Its → possession
Example: The company changed its policy.
It’s → contraction of “it is”
Example: It’s important to review grammar rules regularly.
Learning these small differences can make a big improvement in writing accuracy.
7. Double Negatives
Double negatives occur when two negative words appear in the same sentence. This can confuse readers and weaken the meaning of the sentence.
Incorrect example:
I don’t know nothing about the topic.
Correct example:
I don’t know anything about the topic.
Using only one negative word ensures the sentence is clear and grammatically correct.
8. Misplaced Modifiers
Modifiers describe other words in a sentence. When they are placed incorrectly, they can make sentences confusing.
Incorrect example:
Walking through the classroom, the posters looked interesting.
Correct example:
Walking through the classroom, I noticed the interesting posters.
Placing modifiers near the words they describe helps avoid misunderstandings.
9. Confusing “Affect” and “Effect”
Many writers find it difficult to distinguish between these two words.
Affect is usually used as a verb meaning “to influence.”
Example:
Lack of sleep can affect your concentration.
Effect is usually used as a noun meaning “result.”
Example:
The new study method had a positive effect on student performance.
Remembering the difference between these words can prevent common writing mistakes.
10. Incorrect Comma Usage
Commas are essential for organizing sentences and improving readability.
Incorrect example:
After the class we discussed grammar rules.
Correct example:
After the class, we discussed grammar rules.
Commas are often used to:
- separate items in a list
- separate clauses
- create pauses for clarity
Example:
Students practiced reading, writing, speaking, and listening skills.
