Korean Honorifics Explained: 존댓말 vs 반말
Learn the difference between 존댓말 (formal) and 반말 (casual) Korean. Understand when to use each speech level, with real K-drama examples.
One of the first things that surprises learners about Korean is that it has multiple speech levels — not just vocabulary choices, but entirely different verb endings that signal your relationship to the listener. K-dramas are packed with moments where characters switch speech levels, and understanding this system unlocks a huge layer of emotional meaning.
What Are Korean Honorifics?
Korean honorifics (경어법, gyeong-eo-beop) are a grammatical system embedded directly into verb endings, not just word choice. When you speak to someone older, of higher status, or a stranger, you change the endings of your verbs and adjectives.
The two main levels you need to know are 존댓말 (formal/polite) and 반말 (casual/intimate). Within 존댓말, there are further gradations — 합쇼체 (very formal) and 해요체 (polite but friendly) — but for everyday conversation and dramas, 해요체 is the most common.

존댓말 — Formal/Polite Speech
존댓말 is the default when meeting someone for the first time, speaking to elders, or in professional settings. The most common form is 해요체, which ends verbs with -아요/-어요/-해요.
Notice how even simple sentences change completely when made polite:
안녕하세요.
An-nyeong-ha-se-yo.
Hello. (formal greeting)
The -요 ending signals politeness
어디 가요?
Eo-di ga-yo?
Where are you going?
가다 (to go) → 가요 in 해요체
잘 지냈어요?
Jal ji-naet-seo-yo?
Have you been well?
Common after not seeing someone for a while
감사합니다.
Gam-sa-ham-ni-da.
Thank you. (very formal)
합쇼체 — used in formal settings or service contexts
반말 — Casual Speech
반말 is used between close friends, with younger people, or after explicitly agreeing to drop formalities. In dramas, the shift from 존댓말 to 반말 (말을 놓다) is a significant emotional moment — it signals that two people have become close.
To form 반말, you drop the -요 ending and adjust the vowel:
안녕.
An-nyeong.
Hey. / Bye. (casual)
Both greeting and farewell between friends
어디 가?
Eo-di ga?
Where are you going?
가요 → 가 (drop -요)
잘 지냈어?
Jal ji-naet-seo?
Have you been well?
잘 지냈어요 → 잘 지냈어 (drop -요)
고마워.
Go-ma-wo.
Thanks.
감사합니다 → 고마워 (completely different word root)
When to Switch Speech Levels
In Korean culture, dropping formalities is a deliberate social act. You don't simply start using 반말 — you usually ask permission or both parties mutually agree. The phrase '말 놓을까요?' (Shall we speak casually?) marks a turning point in relationships.
Key rules: • With strangers or in professional settings: always start with 존댓말 • With someone older: always use 존댓말 unless they explicitly tell you otherwise • With peers: start with 존댓말, switch to 반말 once comfortable • With younger people: you can use 반말, but it's still polite to start formal
우리 말 놓을까요?
U-ri mal no-eul-kka-yo?
Shall we speak casually to each other?
The classic way to propose dropping formalities
편하게 말해도 돼요.
Pyeon-ha-ge mal-hae-do dwae-yo.
You can speak comfortably (casually).
Said by the older/higher-status person giving permission
K-Drama Speech Level Moments
K-dramas use speech level shifts as emotional shorthand. Here are the most common patterns:
The cold boss who speaks informally: A powerful character using 반말 signals dominance. When they switch to 존댓말, it shows respect or vulnerability.
The friend-zone-to-romance shift: Childhood friends or coworkers who've been using 반말 for years — there's no dramatic switch, which makes their intimacy feel natural.
The stranger-to-lover switch: The most common drama moment. Two people who started with formal speech slowly drop formalities — sometimes mid-sentence, stumbling, catching themselves. This awkward moment is peak drama tension.
저는 한재윤이에요. 반말 써도 돼요.
Jeo-neun Han Jae-yun-i-e-yo. Ban-mal sseo-do dwae-yo.
I'm Han Jae-yun. You can speak casually.
A character explicitly giving permission to use 반말
야, 너 오늘 왜 이래?
Ya, neo o-neul wae i-rae?
Hey, why are you being like this today?
야 is a casual attention-getter — only used in 반말
