The most common grammatical mistakes and how to avoid them - GF Academy Guide

Grammar mistakes can sneak into anyone’s writing - whether you’re an English learner, a student, or even a native speaker. The problem? They can make your message unclear, reduce your credibility, and sometimes even cause misunderstandings.

The good news is that avoiding the most common grammatical mistakes is easier than you think. With a few practical tips and a little practice, you can write with confidence - and without second-guessing every sentence.

Here are the top grammar mistakes in English and simple ways to fix them.

1. Mixing up “your” and “you’re”
 

This one is a classic.

Your = shows possession (Your phone is on the table.)
You’re = short for “you are” (You’re welcome to join us.)

💡 Quick fix: If you can replace the word with “you are” and it still makes sense, use you’re. If not, go with your.

2. Confusing “its” and “it’s”
 

The difference is small but important.

Its = belongs to “it” (The dog wagged its tail.)
It’s = short for “it is” or “it has” (It’s been a long day.)

💡 Quick fix: Try expanding it to “it is” or “it has.” If it works, you need the apostrophe.

3. Choosing the wrong word
 

Some words look or sound similar but mean completely different things:

effect (noun) vs. affect (verb)
there (place), their (possession), and they’re (they are)
than (comparison) vs. then (time)

💡 Quick fix: When in doubt, check the meaning in a reliable dictionary - even native speakers do it.

4. Forgetting subject-verb agreement
 

Your subject and verb need to match in number:

❌ The list of items are long.

✅ The list of items is long.

💡 Quick fix: Identify the subject first, then choose the correct verb form.

5. Skipping proofreading
 

Rushing through your writing is the fastest way to let grammar mistakes slip through.

💡 Quick fix: Read your text out loud. Use grammar-check tools, but trust your own eyes more than an algorithm.
