Thank You in Korean: Formal, Informal & Replies Guide

Anyone learning Korean quickly bumps into a small puzzle: there isn’t just one way to say “thank you.” Use the wrong version with an elder or a boss, and what was meant as gratitude can land as a breach of etiquette. This guide walks through the three main politeness levels of Korean gratitude, clears up the common spelling confusion between gamsahamnida and kamsahamnida, and explains how to reply when someone thanks you. By the end, you will know exactly which phrase fits each situation.

Common formal expression: (gamsahamnida) ·
Common informal expression: (gomawo) ·
Standard reply to thank you: (cheonmaneyo) ·
Politeness levels: 3 (formal, polite informal, casual)

Three key expressions, one pattern: Korean gratitude shifts with social hierarchy the same way verb endings shift with formality levels.

The implication: picking the wrong level risks sounding rude in a culture that places heavy weight on age and hierarchy. When in doubt, the formal option is always safer.

How do you politely say thank you in Korean?

What is the formal way?

The standard formal expression is (gamsahamnida). This phrase works across nearly every formal situation: addressing a supervisor at work, thanking a stranger who holds a door, or expressing gratitude to an elder at a family gathering. As language educator 90 Day Korean explains, it is the go-to phrase when you are unsure. An alternative formal form is (gomapseumnida), which carries the same politeness level and can be used interchangeably.

What is the informal way?

For close friends or people your own age, (gomawo) is the casual option. This version drops the formal ending entirely and is reserved for relaxed settings. According to wikiHow, it is appropriate with younger siblings, childhood friends, and anyone you would address with casual speech. Between formal and casual sits (gomawoyo) — a polite version that works with acquaintances or coworkers you know reasonably well. The –yo ending softens the phrase without elevating it to the full formal register.

How to pronounce ?

The spelling is but the sound shifts in connected speech. Preply points out that the ㅂ character in the verb stem softens to an “m” sound before the following ㄴ consonant. The result is closer to gamsahamnida than gamsahabnida. The word has four syllables: gam-sa-ham-ni-da, with even stress across each syllable, though a slight emphasis lands on the first syllable according to GetChingu.

The trade-off: formal safety removes ambiguity but can feel stiff among friends. Learning when to drop to the polite intermediate level takes the most practice.

Is it Gamsahamnida or Kamsahamnida?

What is the correct spelling?

The standard Romanization of is gamsahamnida with an initial “g.” This follows the Revised Romanization of Korean system, which maps the consonant ㄱ to “g” even though its actual sound sits closer to an unaspirated “k.” Language guides such as 90 Day Korean consistently use the “g” spelling in their official materials.

Why do people say kamsahamnida?

The pronunciation of the initial consonant in Korean does not perfectly match English categories. The ㄱ character is voiceless and unaspirated, which means it does not have the puff of air that English “k” carries but also lacks the vibration of English “g.” To English ears, the sound sits between both letters, which is why kamsahamnida is a common mishearing among beginners. The Preply pronunciation guide confirms that the sound is technically closer to a soft “g” without the full aspiration of an English “k.”

How to avoid common mistakes

Three patterns trip up learners:

• Dropping the middle syllable: is four syllables, not three. Never shorten it to “kamsamida.”
• Using the aspirated “k”: Practicing with a soft, unaspirated initial sound gets closer to the Korean ㄱ. Try touching the back of your tongue to your soft palate without releasing a burst of air.
• Confusing formality levels in writing: In text messages, it is common to see the informal spelling “ㄱㅅ” (from ‘s first letters) among close friends, but this shorthand should never appear in formal written communication.

The catch: even native speakers sometimes hear Romanization debates differently because regional and individual pronunciation varies. The safest bet is to match the written “g” spelling while aiming for the softer Korean sound.

What is gomawoyo in Korean?

What does gomawoyo mean?

(gomawoyo) is the polite informal version of “thank you.” It sits between the very casual and the formal . iTranslate describes it as a useful intermediate tier for everyday situations that require politeness without full formality — for example, thanking a coworker you share lunch with or a neighbor you know by name.

How is it different from gomawo?

The only difference is the polite ending –yo. (gomawo) drops that ending entirely and is strictly casual. Tandem warns that should never appear in a business setting or toward someone older — it carries a bluntness that can feel disrespectful. Compare the two:

• (gomawo): casual, among close friends and younger people
• (gomawoyo): polite, for acquaintances and comfortable work relationships

When to use gomawoyo vs

The deciding factor is the relationship. If the person is clearly older or holds a higher rank, is the default. If you have a peer-level relationship and would use casual speech in other exchanges, is natural. GetChingu notes that is always appropriate for strangers, while signals a closer, more comfortable dynamic.

What this means: learners who master gain access to a middle register that native speakers use frequently. It avoids the coldness of always using formal speech with friends and the rudeness of dropping to casual with new acquaintances.

When should I use “kamsamida”?

What is the difference between kamsamida and kamsahamnida?

“Kamsamida” is a mispronunciation that drops the middle syllable –ham–. The correct full form is (gamsahamnida). The error often arises because the middle syllable is unstressed and can blur in fast speech, leading learners to hear only three syllables instead of four. No reputable Korean language guide lists “kamsamida” as a valid form.

Is kamsamida correct?

No. The recognized formal expressions are and . “Kamsamida” does not appear in standard Korean textbooks, official language testing materials, or established language guides. If you see “kamsamida” in online forums or subtitles, it is either a typographical error or a deliberate abbreviation used in very informal chat contexts — but it should never be used in speech or writing.

What other expressions are used?

Beyond the core phrases, Korean speakers sometimes borrow the English word in a joking tone. (ttaengkyu) is a phonetic borrowing from English “thank you.” St. Augustine University Explore describes it as joking or very casual rather than a standard expression of gratitude. It might appear among close friends in a playful context but should not be taken seriously.

The pattern: every Korean gratitude expression falls into one of three clear tiers. If a phrase does not map to formal, polite informal, or casual, it is either borrowed slang or a learner mistake.

What do Koreans reply to “thank you”?

What does cheonmaneyo mean?

The standard reply to is (cheonmaneyo), which translates roughly to “you’re welcome.” Busuu notes that in practice, this phrase is used less frequently than English speakers might expect. Korean speakers often respond with a simple nod or a brief acknowledgment rather than a direct verbal equivalent.

How to say ‘you’re welcome’ in Korean?

Two replies cover most situations:

• (cheonmaneyo) – the textbook word-for-word translation, appropriate in formal settings
• (anieyo) – literally “it’s not” or “not at all,” common in polite informal contexts

Other common replies

In everyday conversation, Koreans often skip a verbal reply entirely. A slight head bow, a hand gesture, or simply saying (ne, “yes”) is enough. Busuu explains that a deeper bow (about 45 degrees) is reserved for very formal settings or when thanking someone significantly higher in the social hierarchy. Among friends, a quick nod or smile replaces the bow.

Why this matters: expecting a verbal “you’re welcome” every time can make a learner sound like a textbook. Observing how native speakers downplay the response — often with silence or a simple nod — is a more natural approach.

Pronunciation guide and cultural etiquette

Mastering the sounds of Korean gratitude requires attention to one key rule: the consonant shift in connected speech changes how written syllables are spoken.

Bowing etiquette

Verbal thanks in Korea almost always pair with a physical gesture. Busuu outlines two levels: a slight head bow for thanking older people in casual settings, and a deeper bow of about 45 degrees for formal situations or toward people much higher in rank. When combined with , the bow signals sincerity beyond the words alone.

Step-by-step: How to choose the right phrase

1. Identify the person’s age and status. If they are older or hold a higher position, default to .
2. If the person is a peer or younger acquaintance, consider if you want politeness without full formality.
3. For close friends, intimate family, or children, is appropriate.
4. When in doubt, use . As Hilokal advises, it is safe in almost any context.

The trade-off: always choosing formal speech removes social risk but may create emotional distance. Koreans who are close friends or family use casual language naturally, and using formal speech with them can feel cold.

Clarity: What we know and what remains unclear

“Learning when to switch from to is one of the first signals that a learner understands Korean social dynamics.”

Tandem Language Exchange

“Even a slight head bow changes the tone of your spoken thank you. In Korea, the gesture is part of the gratitude.”
