7 Korean Phrases That Don’t Translate to English

You're bundled up in your warmest coat, watching snowflakes drift past your window with a steaming mug in your hands. Your Korean friend texts you a single word—포근하다—and suddenly you're scrambling through translation apps, only to find they don't quite capture what she means. “Cozy? Warm? Comfortable?” None of these feel exactly right. Welcome to the beautiful frustration of Korean untranslatable words, where single phrases carry emotions and cultural nuances that English simply can't match.

As the cold weather settles in, there's no better time to explore these linguistic gems that reveal how Koreans experience comfort, connection, and warmth in ways uniquely their own. Let's dive into seven Korean phrases that will forever change how you see the language—and maybe even how you see the world.

1. 눈치 (nunchi) – The Art of Reading the Room

눈치 (nunchi) literally translates to “eye measure,” but its meaning runs far deeper than any simple English equivalent. It's the subtle art of gauging other people's moods, reading between the lines, and understanding unspoken social dynamics—all without anyone saying a word.

Think of it as emotional intelligence meets social awareness, Korean style. When someone says “눈치가 빠르다” (nunchi-ga ppareuda), they're complimenting someone who quickly picks up on social cues. Conversely, “눈치가 없다” (nunchi-ga eopda) describes someone who's oblivious to the atmosphere—perhaps talking loudly when everyone else is quiet, or not noticing when it's time to leave.

Practical example:

• When your Korean colleague keeps glancing at the clock during your presentation, someone with good 눈치 would wrap things up quickly
• Noticing your host yawning and saying “I should get going” before they have to hint it's bedtime
• Sensing when your friend needs space versus when they need company, without them explicitly saying so

In Korean culture, 눈치 is essential for maintaining social harmony. It's why direct confrontation is often avoided—people expect others to pick up on subtle signals instead. This concept is so important that parents often teach their children to develop good 눈치 from a young age.

2. 정 (jeong) – A Bond Beyond Love

정 (jeong) might be one of the most discussed untranslatable Korean words, and for good reason. It's often explained as a deep emotional connection, attachment, or affection that develops over time—but that barely scratches the surface.

정 is the feeling you get with someone you've shared countless meals with, someone whose quirks annoy you but whose absence would leave a hole in your life. It's deeper than friendship, more complex than love, and can exist even between people who sometimes drive each other crazy. You can have 정 with your neighborhood ahjumma who scolds you but always gives you extra banchan, or with a coworker you've worked alongside for years.

Cultural context:

The phrase “정이 들었어” (jeong-i deureosseo) means “I've developed jeong for you/this.” Koreans might say this about a beat-up old car they can't bear to sell, a restaurant they've frequented for decades, or a person who's become irreplaceable in their life. There's even “미운 정” (miun jeong)—affection for someone despite finding them frustrating or difficult.

During cold winter months, 정 is what keeps communities warm. It's the neighbor who brings you homemade kimchi, the friend who knows exactly when you need company, the bonds that make Korean society so interconnected.

3. 애교 (aegyo) – Charming Cuteness with Purpose

애교 (aegyo) is often translated as “cuteness” or “charm,” but it's actually a deliberate display of endearing behavior—think puppy-dog eyes, a higher-pitched voice, playful gestures, or exaggerated pouts designed to be adorable.

While this might sound childish to Western ears, 애교 is a recognized social skill in Korea. It's used to lighten the mood, get out of trouble, or simply make someone smile. Both children and adults deploy 애교, though it's particularly associated with women and K-pop idols who've turned it into an art form.

When Koreans use 애교:

• Asking for a favor from a friend: “오빠~” (oppa~) said in a drawn-out, sweet voice
• Apologizing for a small mistake in a charming way rather than seriously
• Cheering someone up when they're having a bad day
• Creating a playful, affectionate atmosphere in relationships

The phrase “애교가 많다” (aegyo-ga manta) means someone has a lot of aegyo—they're naturally charming and know how to be endearing. Understanding these cultural nuances is part of what makes language learning so fascinating.

4. 한 (han) – Collective Sorrow and Resilience

한 (han) is perhaps the most profound and complex concept on this list. It's a collective feeling of deep sorrow, grief, and unresolved resentment that comes from historical injustice, suffering, or unfulfilled dreams. But it's not just sadness—it's intertwined with endurance, resilience, and the strength to carry on despite hardship.

Rooted in Korea's tumultuous history of invasions, colonization, and war, 한 is considered a fundamental emotion in Korean culture. It appears in traditional music (pansori), literature, and even modern K-dramas where characters endure hardship with quiet dignity.

Understanding 한 in context:

한 isn't something you express casually in daily conversation. Instead, it's a philosophical concept that helps explain Korean emotional depth, artistic expression, and cultural resilience. You might hear it discussed in relation to historical events, in analysis of Korean cinema, or when talking about the emotional depth in Korean performing arts.

The related phrase “한이 맺히다” (han-i maethida) means to harbor deep resentment or sorrow—a feeling of injustice that sits heavy in your heart. Understanding 한 gives you insight into why Korean storytelling often features themes of endurance, delayed justice, and emotional catharsis.

5. 답답하다 (dapdaphada) – Frustrated Stuffiness of the Heart

답답하다 (dapdaphada) is usually translated as “frustrated” or “stuffy,” but neither captures its full meaning. It describes that suffocating feeling when things aren't moving forward, when you're stuck in a situation with no clear solution, or when someone just doesn't get what you're trying to explain.

The word can describe both physical sensations—like a stuffy room or tight chest—and emotional ones. When someone lacks 눈치 and you have to spell everything out for them, you might feel 답답하다. When winter air feels heavy and you need to open a window, that's also 답답하다.

Common situations that are 답답하다:

• Explaining something obvious multiple times to someone who still doesn't understand
• Being in a situation where you want to help but can't
• Watching someone make poor decisions and being unable to intervene
• Feeling emotionally suffocated in a relationship or situation
• Physical stuffiness from poor ventilation or chest congestion

You might say “가슴이 답답해” (gaseum-i dapdaphae) when your heart feels heavy and constricted, or “답답해 죽겠어” (dapdaphae jukgesseo)—literally “I'm so frustrated I could die”—when someone's lack of understanding is driving you up the wall.

6. 보고 싶다 (bogo sipda) – Missing Someone Beyond Words

보고 싶다 (bogo sipda) is typically translated as “I miss you,” but the literal meaning reveals something deeper: “I want to see you.” This isn't passive longing—it's an active desire for someone's presence.

During cold winter months when gathering becomes more precious, Koreans use this phrase to express the specific ache of wanting to be with someone. It's more immediate and visceral than the English “I miss you”—it's about wanting to physically see their face, share space with them, experience their presence.

The layers of 보고 싶다:

You can use this phrase for people (“엄마 보고 싶어” – “I miss Mom”), places (“고향이 보고 싶다” – “I miss my hometown”), and even foods or experiences. The intensity can be adjusted: “많이 보고 싶어” (mani bogo sipeo) means “I miss you a lot,” while “너무 보고 싶어” (neomu bogo sipeo) expresses overwhelming longing.

What makes this phrase special is its specificity—it's not just remembering someone fondly, but actively wanting to bridge the distance between you. It's the perfect phrase to text a friend on a cold evening when you wish they were there to share a warm meal with you.

7. 수고하셨습니다 (sugohasyeotseumnida) – Acknowledging Effort and Hard Work

수고하셨습니다 (sugohasyeotseumnida) is commonly translated as “good job” or “thank you for your hard work,” but it's so much more nuanced. It's an acknowledgment of someone's effort, regardless of outcome—a recognition that they tried, that they put in work, that their labor is seen and appreciated.

This phrase is everywhere in Korean daily life. Coworkers say it to each other at the end of the day. Customers say it to service workers. Team members say it after finishing a project. It creates a culture of mutual recognition where effort itself is valued.

When to use 수고하셨습니다:

• To coworkers leaving the office: “오늘도 수고하셨습니다” (oneuldo sugohasyeotseumnida) – “Thank you for your hard work today”
• To delivery drivers, cashiers, or service workers completing their task
• After collaborating on a project, regardless of success
• To acknowledge someone's effort even if things didn't work out perfectly

The related phrase “수고했어” (sugohaesseo) is the casual version used with friends and younger people. There's also “수고 많으셨어요” (sugo maneusyeosseoyo) for when someone put in exceptional effort.

What makes this uniquely Korean is the cultural value it represents—that hard work and effort deserve recognition independent of results. It builds workplace camaraderie and social connection in a way that English's task-focused “good job” doesn't quite capture.
