Common Grammar Mistakes to Avoid

1. Using “a” and “an” incorrectly

❌ Wrong	✅ Correct	Explanation
I have an dog.	I have a dog.	Use “a” before consonant sounds and “an” before vowel sounds.
She is a engineer.	She is an engineer.	“Engineer” starts with a vowel sound (e).

🟢 Tip: Focus on the sound, not just the letter. For example, we say “an hour” (because the “h” is silent).

2. Confusing “your” and “you’re”

❌ Wrong	✅ Correct	Explanation
Your welcome.	You’re welcome.	“You’re” = “you are”. “Your” shows possession.

Example:

Your bag is on the chair. (possession)
You’re amazing! (you are)

3. Missing “s” in third person singular verbs

❌ Wrong	✅ Correct	Explanation
He walk to school.	He walks to school.	Always add -s to verbs with he/she/it.

Example:

She plays the piano every day.
It rains a lot in winter.

4. Mixing up “much” and “many”

❌ Wrong	✅ Correct	Explanation
I have much books.	I have many books.	Use many with countable nouns, much with uncountable nouns.

Example:

Many people like coffee.
I don’t have much time.

5. Forgetting prepositions after verbs

Some verbs need prepositions — skipping them is a common beginner mistake.

Verb	Common Preposition	Example
Listen	to	Listen to music.
Depend	on	It depends on the weather.
Wait	for	I’m waiting for my friend.

6. Using double negatives

❌ Wrong	✅ Correct	Explanation
I don’t need no help.	I don’t need any help.	In English, use only one negative.

Example:

I don’t know anything. (✅)
I don’t know nothing. (❌)

7. Mixing up “in”, “on”, and “at”

Preposition	Used For	Example
In	months, years, countries	I was born in 2000.
On	days, dates, surfaces	See you on Monday.
At	time, exact place	Let’s meet at 6 p.m.
