Introduction
English grammar doesn’t have to be difficult. Many learners across Thailand, China, and Asia often struggle with the same grammar patterns. The good news? These mistakes are easy to fix once you understand why they happen.
Here are the three most common mistakes — and the simple solutions.
1. Confusing “He/She” and “His/Her”
In many Asian languages, pronouns do not change based on gender, so learners often mix these up.
Incorrect:
She forgot his bag.
He loves her sister (but you meant “his sister”).
Correct:
She forgot her bag.
He loves his sister.
Quick Fix:
Think of the person first → then choose the right gendered pronoun.
2. Forgetting the Past Tense
A very common error is using present tense when talking about the past.
Incorrect:
Yesterday I go to the mall.
Last year I study English.
Correct:
Yesterday I went to the mall.
Last year I studied English.
Quick Fix:
If the sentence has yesterday, last year, last week, or a date → use past tense.
3. Omitting “S” for Third Person Singular
This is one of the most universal mistakes among Asian learners.
Incorrect:
He go to school.
She like coffee.
Correct:
He goes to school.
She likes coffee.
Quick Fix:
If the subject is he / she / it, always add –s / –es to the verb.
