Thank You in Korean: Formal & Informal Phrases Guide

Few things open doors in a new language faster than a genuine “thank you” — but in Korean, the way you say it signals exactly where you stand in the social hierarchy. With about 80 million speakers worldwide, Korean relies on a system of speech levels that determine whether you reach for (gamsahamnida) or keep it casual with (gomawo).

Formal Polite: · Informal Polite: · Casual: · Speakers: ~80 million

Six expressions, one clear divide: Korean gratitude runs on a formality spectrum. The table below shows the core phrases and their literal roots.

How to say thank you in Korean politely?

Understanding Korean speech levels

Korean has seven speech levels, but everyday gratitude uses three main ones. The formal polite level (hapsyoche) is reserved for people older, higher-ranking, or unfamiliar. The informal polite (haeyoche) sits in the middle — polite but warmer. The casual (haerache) is only for close relationships. Misusing them can be seen as rude or awkwardly distant. HiLokal (language learning platform) notes that greetings use the same logic.

The most common polite expression: (gamsahamnida)

(pronounced gam-sa-ham-ni-da) is the go-to thanks in any formal or uncertain situation. According to Busuu (language learning app), it’s “the standard polite expression most learners are advised to use when in doubt.” The first syllable comes from the Chinese character (gǎnxiè), meaning “feeling of thanks.”

• Use with strangers, elders, bosses, teachers, service staff.
• Often accompanied by a slight bow. HiLokal mentions that the bow is a natural part of showing respect.
• Safe in writing (emails, messages) as it’s always polite.

The implication: master first, then branch out.

What is the difference between gamsahamnida and gomawoyo?

(gamsahamnida) – formal polite

is the most formal of the common “thank you” phrases. Tandem categorizes it as “formal and polite” — the kind you’d use in a speech, at work, or with a grandparent. Its Sino-Korean origin gives it a slightly more official tone than native Korean alternatives.

(gomawoyo) – informal polite

bridges the gap between stiff formality and too-casual. Migaku (language learning tool) describes it as “sitting between formal and informal speech.” Native Korean in origin ( means “to be grateful”), it’s warmer than yet still respectful. Use it with colleagues you know well, neighbors, or classmates your own age.

Contexts for each expression

• : first meeting, customer service, formal events, any situation where you can’t lose.
• : work friends, regular acquaintances, hosts of a meal, when you want to sound warm but proper.
• Never mix up the two for the same person twice — consistency signals social awareness.

The pattern: is the “just right” zone for intermediate relationships.

How do you say thank you in Korean informally?

(gomawo) – informal

(go-ma-wo) is the casual drop-in for “thanks.” According to Tandem, it’s used with close friends, siblings, or people of the same age or lower status. The pronunciation is straightforward, but the social rule is strict.

• Use with your best friend, younger cousin, or your pet.
• Never use with a boss, a professor, or someone you’ve just met.
• Adding (jeongmal) before makes it “really thanks” — still informal.

When to use informal thanks

Informal isn’t rude — it’s a signal of closeness. Koreans use among peers in casual settings: after a friend buys coffee, a sibling lends a hand, or a teammate helps with a task. Tandem warns that using in business settings is “discouraged” because it can come across as disrespectful.

Avoiding rudeness in informal settings

If you’re unsure whether informal is appropriate, err on the side of polite. A Korean acquaintance your age might expect until you’ve developed a closer friendship. Watch for their lead — if they switch to (casual speech) with you, you can safely use in return.

What is the correct pronunciation of thank you in Korean?

Phonetic breakdown of

The standard pronunciation is gahm-sah-ham-nee-dah. Busuu provides a clear audio guide: (gamsa) + (hamnida). The ㅂ in is pronounced as ‘m’ before the ‘n’, which is why it sounds like “ham-ni-da” not “hab-ni-da.” In fast native speech, it may compress to gam-sam-ni-da, as Migaku notes.

Common mispronunciations

• “Kamsahamnida” (hard ‘k’): Korean starts with a soft, unaspirated ‘g’ — like ‘g’ in “go” not ‘k’ in “kite”.
• “Gamsahabnida”: Over-pronouncing the ㅂ as ‘b’ instead of the assimilated ‘m’.
• “Gomawoyo” with a hard ‘g’: similar issue — make it soft.

Audio examples

Although we can’t embed audio here, Busuu and Tandem both offer recordings of each phrase. Slow down, break the syllables, and practice the ‘ham-ni-da’ blend. Repetition with a mirror helps you see the mouth shape — lips together for the ‘m’ sound.

The catch: pronunciation accuracy matters more in Korean than in English because small changes shift meanings. Nail the sounds, and locals will compliment your Korean.

How do you respond when someone says thank you in Korean?

Common replies to thank you

The most frequent response to is (anieyo), meaning “it’s nothing” or “you’re welcome.” HiLokal lists it as the default polite reply. Another option is (cheonmaneyo), which is more formal and translates closer to “you’re welcome.” However, is less common in daily speech; Koreans mostly use .

• (anieyo) — polite, all-purpose “don’t mention it.”
• (cheonmaneyo) — formal “you’re welcome” (use with very formal situations).
• (gwaenchana) — informal “it’s okay” (use with close friends).

Formal versus informal responses

Match the response to the speech level. If someone says formally, reply with or . If a friend says , you can say . Tandem advises against mixing levels — replying to a formal thank-you with would be too casual.

What this means: The reply system is simpler than the thanks system — just match the level. Foreigners make fewer mistakes here, but forgetting altogether (silence) is the real faux pas.

How to say thank you in Korean: Step-by-step guide

Step 1: Know your relationship

Before speaking, assess the person’s age relative to yours, your social rank (boss, colleague, stranger), and the formality of the setting. Tandem calls this “the most important first step” for any Korean learner.

Step 2: Choose the right speech level

Use this decision tree:

• Elder/boss/stranger → or
• Acquaintance/colleague same age →
• Close friend/family/younger →
• Deep gratitude or special occasion →

Step 3: Nail the pronunciation

Practice each phrase slowly. : break it as gam-sa-ham-ni-da. : go-ma-wo-yo. : go-ma-wo. Tandem and Busuu both stress that the soft ‘g’ and the ‘ham-ni-da’ assimilation are the trickiest parts for English speakers.

Step 4: Add a slight bow (optional but appreciated)

HiLokal notes that a small bow of the head while saying shows extra respect. In informal settings with friends, a nod is enough.

Step 5: Learn the reply

If someone thanks you, say (polite) or (informal). Silence can be perceived as awkward. Practice the back-and-forth until it feels natural.
