3. Common Mistakes to Avoid

Many English speakers mistakenly use the object particle 을/를 because they think

of "become" as an action verb.

However, 되다 is always used with 이/가, not 을/를.

❌ Incorrect

선생님을 되다

This sentence is incorrect because 을 should not be used with 되다.

⭕ Correct

선생님이 되다

→ to become a teacher

• 선생님 + 이 되다

• Correct particle: 이

-Quick Tip-

되다 + 이/가

✅ 학생이 되다

✅ 의사가 되다

✅ 선생님이 되다

-NOT 되다 + 을/를-

❌ 학생을 되다

❌ 의사를 되다

❌ 선생님을 되다

-Remember-

N(이)가 되다 = "become ~"

Always use 이/가 with 되다, never 을/를!
