Common Grammar Mistakes Every Learner Should Avoid

Learning English can be exciting, but grammar rules often confuse even the best learners. A single misplaced word or comma can change the entire meaning of a sentence. As an experienced English Tutor in English, Book Tutor helps learners recognize these common grammar mistakes and turn them into learning opportunities.

1. The “Your” vs. “You’re” Confusion

It’s one of the first mistakes most learners make.

  • Your means something belongs to you (Your notebook is new).
  • You’re means you are (You’re doing great in class!).

A simple tip: if you can replace it with you are, use you’re.

2. “Its” or “It’s”?

They sound identical but mean different things.

  • Its = possession (The dog wagged its tail).
  • It’s = it is or it has (It’s time for your lesson!).
    Remember, apostrophes never show possession for it.

3. Tense Trouble

Mixing up tenses is a common habit among learners.
I am go to school yesterday.
I went to school yesterday.

A good English Tutor in English, like Book Tutor, helps students practice real-life sentences to make tense use feel natural.

4. Skipping Articles

Small words like “a,” “an,” and “the” make a big difference.
I saw movie yesterday.
I saw a movie yesterday.

Articles are short but powerful. Do not leave them out.

5. Preposition Overload

Many students add prepositions they don’t need.
Where are you going to?
Where are you going?

Each preposition should have a purpose. Unnecessary ones make sentences sound awkward.

6. Subject and Verb Don’t Match

A sentence should always have matching subjects and verbs.
He go to school every day.
He goes to school every day.

Read your sentences aloud. If they sound wrong, they probably are.

7. Adjectives vs. Adverbs

Learners often mix them up.
She runs quick.
She runs quickly.

An English Tutor in English can guide you to recognize the right form automatically while speaking or writing.

8. Missing or Wrong Punctuation

Punctuation shapes meaning.
Let’s eat grandma!
Let’s eat, grandma!

A single comma can save grandma and your sentence.

9. Double Negatives

Two negatives don’t make a positive in English grammar.
I don’t know nothing.
I don’t know anything.

Use one negative per sentence to stay clear and correct.

10. Word Order Mistakes

English follows a natural flow: Subject + Verb + Object.
Always I drink coffee in the morning.
I always drink coffee in the morning.

Practice this pattern regularly and it will become second nature.
