There is something disarming about a language that bows before it speaks.

Korean does not merely encode information. It encodes relationships. Every verb ending is a social contract – a declaration of how you see the person standing in front of you. In English, “please sit down” works for your boss and your dog. In Korean, you’d better know the difference between 앉으세요 and 앉아, or you will insult one and confuse the other.

I have been collecting notes on Korean for a few years now. What follows is a distillation of those notes, organized not as a textbook would but as a learner actually encounters the language: in gyms, in novels, in text messages, and in the strange space between what is said and what is meant.

The Architecture of Hangul

King Sejong the Great (세종대왕) invented Hangul in 1443, and the story is almost too good to be true. The consonant shapes are modeled after the physical position of the tongue and mouth when you pronounce them:

• ㄱ (g/k): the back of the tongue rising toward the soft palate
• ㄴ (n): the tongue touching the upper gum ridge
• ㅁ (m): the shape of closed lips
• ㅅ (s): the shape of a tooth
• ㅇ (ng/silent): the shape of the throat

Vowels are built from three elements: a dot (representing the sun/heaven), a horizontal line (the earth), and a vertical line (a person standing). From these three primitives, the entire vowel system unfolds:

This is a writing system designed by committee – but the good kind, the kind where the committee included phonologists. The result is that Korean is arguably the most rationally designed script in active use anywhere on Earth.

Pronunciation: The Rules They Don’t Teach First

Two rules I picked up early that cleared up a lot of confusion:

1. ㅅ before ㅣ or ㅑ/ㅕ/ㅛ/ㅠ becomes “sh”

The consonant ㅅ is normally an “s,” but place it before any “i” or “y” vowel and it palatalizes to “sh.” This is why 시 sounds like “shi” and 신문 (newspaper) is “shin-mun,” not “sin-mun.” The word 시작 (beginning) is “shi-jak,” and 식당 (restaurant) is “shik-dang.”

2. The silent 받침

When ㄹ sits in the 받침 (bottom consonant position), it behaves differently than you’d expect. Korean syllable blocks stack consonants and vowels into squares, and the bottom slot – the 받침 – follows its own rules of liaison and assimilation. The consonant at the bottom of one syllable bleeds into the top of the next, creating pronunciation chains that make spoken Korean sound nothing like its spelling suggests.

For example:

• 독립 (independence) is pronounced “dong-nip” not “dok-lip”
• 한국어 (Korean language) is pronounced “han-gu-geo” – the ㄱ 받침 links to the next syllable’s vowel

Grammar: Hierarchy in the Verb

Korean has seven speech levels, though modern usage mostly collapses these into four. The critical insight is that the verb ending changes based on your relationship to the listener – not the subject, the listener:

The same verb 가다 (to go) is four different social acts depending on the ending. Get it wrong and you’ve made a statement about the relationship, not about where you’re going.

Conjugation in Practice

Unlike European languages with their tables of person and number, Korean verbs don’t conjugate for who is doing the action. They conjugate for how you feel about the person you’re talking to. The subject is often dropped entirely. Context carries it.

Here is 먹다 (to eat) across several constructions:

Notice how the stem 먹 stays constant while the endings do all the work. This is the agglutinative nature of Korean: you stack suffixes like LEGO bricks.

The Particles: Small Words, Heavy Lifting

Korean particles are postpositions – they attach after the noun, not before it. And they do everything.

The distinction between 은/는 (topic) and 이/가 (subject) is one of the deepest rabbit holes in Korean linguistics. Roughly: 은/는 sets the frame (“as for X…”), while 이/가 identifies (“it is X that…”). The sentence 제가 학생이에요 emphasizes that I am the student (maybe someone asked “who’s the student?”), while 저는 학생이에요 simply states the fact about me.

At the Gym: 헬스장에서

Some of the most useful Korean I’ve picked up comes from the gym. The phrasebook doesn’t prepare you for wanting to ask someone if they’re done with the squat rack:

And the vocabulary that comes with the culture:

• 헬창 – literally an abbreviation meaning something like “health fiend.” Used as a playful, almost affectionate compliment among gym-goers, though it sounds crude to outsiders. Think “gym rat” but with more edge.
• 빵빵하다 – describes big, pumped muscles. 근육이 빵빵! (“Muscles are poppin’!”)
• 오운완 (abbreviation of 오늘도 운동 완료했다) – “Finished my workout for today.” The hashtag of Korean fitness Instagram. Sometimes abbreviated further to just ㅇㅇㅇ, because even abbreviations get abbreviated.

The counter system reveals itself here too: 끼 is the counter for meals (하루에 몇 끼?), 세트 borrows the English “set,” and 체지방 (body fat) and 체중 (body weight) share the hanja character 체 (body, 體).

Reading Korean Literature: 선화 by 김이

The jump from textbook Korean to literary Korean is a canyon. I tried reading 선화 by 김이, published by 은행나무, and the opening pages alone were a vocabulary tsunami. But the prose was beautiful:

나는 타인의 흉터를 빤히 쳐다보는 버릇이 있었다.

“I had a habit of staring intently at other people’s scars.”

누구든 상처가 있다. 상처에서 흐르던 피가 굳고 딱지가 내려앉고, 딱지가 떨어진 자리에 솟은 새살이 바로 상처를 반추하게 하는 흉터였다.

“Everyone carries wounds. The blood that flowed from wounds dries, scabs settle, and the new flesh that rises where scabs have fallen – that is the scar that makes you ruminate on the wound.”

세상에 나만 흉터가 있는 게 아니었으니까.

“Because I wasn’t the only one in the world with scars.”

The vocabulary of wounds and healing in Korean is evocative:

수고하세요: The Farewell That Means “Work Hard”

I wrote about this in Shtetl Length, but it deserves elaboration here.

수고하세요 is a casual farewell rooted in Korean work culture. It literally means something like “please labor/exert yourself,” but in practice it functions as “good work, see you later” or “keep it up.” The upper politeness register manifests as 수고하셨어요 or 수고하셨습니다, used when:

1. A colleague has finished a full day of work: “Great job today + goodbye”
2. Someone (like a cashier) has done effort on your behalf: “Thank you for your effort”

As the customer, you could say 수고하셨습니다 as a gesture of gratitude – acknowledging the work the other person has done.

The grammar is revealing:

• 수고 (苦勞): labor, exertion, toil
• 하세요: polite imperative of 하다 (to do) – “please do”
• 하셨어요: past tense honorific – “you did (honorably)”
• 하셨습니다: past tense formal honorific – the most deferential form

So the farewell literally commands someone to work hard, and the thank-you literally praises them for having worked hard. Working hard is as common a social invocation in Korean culture as invoking God in Latin cultures, or saying “take care” in English. Except 수고하세요 is more specific – it does not wish you wellness, it wishes you productive suffering.

The Korean Keyboard: 두벌식

Learning to type in Korean is its own adventure. The standard Korean keyboard layout (두벌식, “two-set”) splits consonants to the left hand and vowels to the right:

ㅂ ㅈ ㄷ ㄱ ㅅ  ㅛ ㅕ ㅑ ㅐ ㅔ
 ㅁ ㄴ ㅇ ㄹ ㅎ  ㅗ ㅓ ㅏ ㅣ
  ㅋ ㅌ ㅊ ㅍ   ㅠ ㅜ ㅡ

Hold Shift for tense consonants (ㅃ ㅉ ㄸ ㄲ ㅆ) and compound vowels (ㅒ ㅖ). The layout is phonetically organized: consonants on the left, vowels on the right. Your hands alternate with almost every keystroke, which makes Korean typing surprisingly rhythmic once you internalize it.

My early keyboard practice files are pure gibberish – mashing keys to build muscle memory. The word 산화 (oxidation) sits at the bottom of one such file, a lone recognizable word in a sea of random jamo. Progress, I suppose, is measured in the ratio of intelligible words to noise.

What Korean Teaches You About Language

Every language you learn restructures how you think. Spanish taught me that objects can have gender. Portuguese taught me that the subjunctive is not optional. French taught me that spelling and pronunciation exist in separate universes. But Korean taught me something more fundamental: that grammar can encode social relationships, that the verb is not just an action but a posture.

The language forces you to decide, before you open your mouth, who you are in relation to the person you’re speaking to. There is no neutral register. Every sentence is a tiny act of social positioning. And once you internalize this, you start noticing how English accomplishes the same thing through different mechanisms – tone, word choice, the presence or absence of “please” – all the implicit hierarchy that Korean makes explicit.

한국어를 배우는 것은 끝이 없는 여행입니다. 하지만, 그 여행이 제일 재미있는 부분이에요.

Learning Korean is a journey without end. But the journey is the best part.
