Korean Has Three Basic Speech Styles


Korean has three main verb endings: the Hamnida style, the Haeyo style, and the Handa style.

Each one is used depending on the situation and the person you’re speaking to.

Today, let’s take a closer look at the differences between these three styles!
(Detailed explanations for each ending will be covered in separate articles!)

Formal Style — 합니다 (hamnida)

The hamnida style is the most formal verb ending in Korean.
It’s used when speaking to superiors, teachers, or people you’re meeting for the first time.

Example:
저는 한국어를 공부합니다.
jeoneun hangugeoreul gongbu-hamnida
Meaning: I study Korean.

You’ll hear this style often in dramas and official situations.
Whenever you hear a verb ending in –니다 (-nida), you can recognize it as the hamnida style.

Polite Conversational Style — 해요 (haeyo)

The haeyo style is the most commonly used form in everyday conversation.
It’s less formal than hamnida-style, yet still polite and friendly.

You can use it when talking to store staff, café workers, or people you’re not very close with—
which is why I recommend Korean learners start with the haeyo style first!

Example:
저는 한국어 공부해요.
jeoneun hangugeo gongbu-haeyo
Meaning: I’m studying Korean / I study Korean.

When you hear a verb ending in –요 (-yo), you’re hearing the haeyo style.
You’ll notice it a lot in YouTube videos, K-dramas, and variety shows—try listening for it!

Casual Style — 한다 (handa)

The handa style is also known as banmal, meaning casual or “informal speech.”
It’s used among close friends or in very casual settings.
Using it with superiors or people you’ve just met can be considered rude.

Since Korean culture places importance on hierarchy,
make sure to use this style only with people you’re close to.

Example:
나 한국어 공부한다.
na hangugeo gongbu-handa
Meaning: I study Korean. (casual)

By the way, the writing section of the TOPIK exam requires you to write in the handa style.
So if you’re planning to take TOPIK in the future, it’s definitely a style worth learning.
