Korean Grammar Made Easy: -아/어 주다

One of the easiest ways to make your Korean sound more natural, warm, and polite is by learning how to use -아/어 주다.

In English, we simply say things like “buy,” “help,” or “teach.”

But in Korean, native speakers often add 주다 (“to give”) to show that they are doing something for someone else’s benefit.

It may look like a small grammar point, but it completely changes the feeling of a sentence!

1. Plain Action vs. Doing Something for Someone

When you use a verb alone, you are simply describing an action.

But when you add -아/어 주다, it adds the meaning of:

• doing something for another person

• helping someone

• doing a favor

  
  

Compare these examples:

• 사진을 찍어요.

→ “I take photos.”

• 사진을 찍어 줘요.

→ “I take a photo for you.”

→ (It sounds warmer and more thoughtful.)

• 한국어를 가르쳐요.

→ “I teach Korean.”

• 한국어를 가르쳐 줘요.

Why Is This Grammar Important?

In Korean culture, showing consideration for others is very important.

Because of this, Korean speakers often use -아/어 주다 when:

• helping someone

• offering a favor

• making polite requests

• talking about kind actions

Without it, a sentence can sometimes sound more direct or less personal than intended.

This is why native Koreans use this grammar all the time in daily conversation!

2. How to Make -아/어 주다

The conjugation follows the same rule as the present tense (-아/어 요).

① If the verb stem has ㅏ or ㅗ → add -아 주다

• 사다 (to buy) → 사 주다

• 닫다 (to close) → 닫아 주다

② If the verb stem has other vowels → add -어 주다

• 만들다 (to make) → 만들어 주다

• 읽다 (to read) → 읽어 주다

③ For 하다 verbs → change to 해 주다

• 요리하다 (to cook) → 요리해 주다

• 설명하다 (to explain) → 설명해 주다

Special Note: 도와주다

You may notice that Koreans say:

• 도와주다 = “to help”

In Korean, helping someone already implies doing something for another person, so the verb itself naturally includes 주다.

That’s why “도와요” is not commonly used by itself.

Buying coffee for a friend	커피 샀어요.	커피 사 줬어요.
Offering to explain something	설명할게요.	설명해 줄게요.

Adding -아/어 주다 makes the sentence sound more considerate and personal.
