So, you're wondering what language do they speak in Korea? On the surface, it’s a simple answer. They speak Korean. But honestly, if you’ve ever sat in a bustling cafe in Seoul or hiked the rugged trails of Jeju Island, you’ve probably noticed that "Korean" sounds remarkably different depending on who’s talking.
It is a fascinating, complex beast of a language. It’s got a history that reads like a political thriller and a writing system that is basically the gold standard for linguistic design.
The Standard: Seoul and the Gyeonggi Dialect
Most people who learn the language through apps or textbooks are learning the Gyeonggi dialect. This is the "Standard Korean" (표준어, pyojuneo). It’s what you hear on the nightly news and in most K-dramas. It is generally described as being polite, somewhat melodic, and—compared to the regional accents—fairly soft.
In the 21st century, the Seoul dialect has become the dominant force. Because the capital is such a massive cultural and economic hub, younger people from all over the country are moving there and adopting the Seoul way of speaking. It’s kinda like how a "neutral" accent becomes the default in many countries.
The Soul of the Provinces: Satoori
But don't be fooled. Step outside the capital and you'll run into satoori (사투리). These are the regional dialects that give the Korean peninsula its flavor.
Gyeongsang-do (The Rough and Tumble)
If you go to Busan or Daegu, the language changes instantly. People often say Gyeongsang speakers sound like they are fighting, even when they’re just asking for the salt. It’s got a much stronger pitch accent and a "manly" or aggressive reputation. Instead of the standard ending ~ni? for questions, you’ll hear them use ~na? or ~no?. It’s punchy. It’s fast. It’s distinct.

Jeolla-do (The Soulful Flow)
Over in the southwest, the Jeolla dialect is known for being expressive and a bit "salty" in a good way. They have this famous filler word, geoshigi (거시기). It basically means "that thing" or "whatshisname." You use it when you can't remember a word. A Jeolla speaker can hold a whole conversation using geoshigi five times in a sentence, and everyone knows exactly what they mean.
Jeju-do (The Foreign Island)
Then there is Jeju Island. Honestly, Jeju satoori is so different that some linguists consider it a separate language entirely. Because it's an island, the dialect preserved ancient words and grammatical structures that died out on the mainland centuries ago. If a grandmother in a rural Jeju village starts speaking to you in her native tongue, even a native Seoulite might just blink and smile, having no idea what she said.
Hangul: The World’s Most Scientific Script
You can’t talk about what language do they speak in Korea without talking about Hangul.
Before the mid-1400s, Korea used Chinese characters (Hanja). The problem? Chinese is incredibly hard to learn, and the grammar is totally different from Korean. This meant that only the rich and powerful could read or write. King Sejong the Great, who is basically a superhero in Korean history, decided this was nonsense.
In 1443, he created Hangul. It’s a phonetic alphabet designed to be so simple that "a wise man can learn it in a morning, and a fool can learn it in ten days." The shapes of the consonants are actually modeled after the shape your mouth and tongue make when you say them.

- Logic: Words are built in syllable blocks, not a long string of letters.
- Accessibility: It skyrocketed literacy rates.
- Identity: It’s a huge point of national pride. Today, both North and South Korea use it, though they call it different names (Hangul in the South, Chosongul in the North).
The North-South Divide: A Growing Gap
Here is where it gets heavy. Since the peninsula was split in 1945, the language has started to drift apart. It’s been over 70 years of zero communication between the general publics.
In South Korea, the language is dynamic and open. It is absolutely packed with English loanwords. They call this Konglish. If you want a laptop, you ask for a noteu-buk. If you’re talking about a cell phone, it’s a haendeupon (hand phone).
In North Korea, the government has actively tried to "purify" the language. They’ve scrubbed out foreign loanwords and replaced them with native Korean inventions.
| Item | South Korean (Loanword) | North Korean (Native/New) |
|---|---|---|
| Ice Cream | aiseu-keulim | eoreum-gwaja (ice snack) |
| Juice | juseu | danmul (sweet water) |
| Shampoo | syampu | meorimul-binu (hair water soap) |
While they can still understand each other—it's roughly 60-70% the same in everyday conversation—the specialized terms for technology, medicine, and law are now wildly different. Defectors from the North often have to take language classes in the South just to navigate a grocery store or a doctor's office.
The Role of Hanja (Chinese Characters)
You might wonder if those old Chinese characters are gone. Not quite. While North Korea banned them entirely, South Korea still uses them in specific ways.

You won't see Hanja in a text message or a novel, but you’ll see them in:
- Newspaper headlines: To save space (one character can represent a whole word).
- Legal documents: To ensure there is no ambiguity between words that sound the same but have different meanings.
- Calendars and menus: Often for "Big," "Medium," and "Small."
- Names: Almost every Korean person has a name that corresponds to specific Hanja characters with a unique meaning.
What You Need to Know if You’re Visiting
If you're planning a trip, don't sweat the dialects too much. Everyone understands the standard Seoul dialect because of TV and education.
What's more important is honorifics. Korean is a hierarchical language. How you speak depends entirely on your relationship with the person you're talking to. You use different verb endings for your boss, your grandmother, and your best friend.
Actionable Insight for Travelers:
- Learn the "Yo" rule: If you're a tourist, almost every sentence you say should end in ~yo. It’s the standard polite ending. It’s safe. It won't get you in trouble.
- Body language matters: A small bow when saying Annyeonghaseyo (Hello) goes further than perfect pronunciation.
- Konglish is your friend: If you don't know the Korean word for "Bus," "Taxi," "Coffee," or "Computer," just say the English word with a Korean accent. Chances are, they'll know exactly what you want.
Understanding what language do they speak in Korea is really about understanding the people—proud of their history, incredibly adaptive to the modern world, and deeply connected to their regional roots. Whether you're listening to the sharp accent of a Busan fishmonger or the polished tones of a Seoul news anchor, you're hearing a language that has survived against all odds.
Next Steps for Deepening Your Knowledge:
- Check out the National Institute of Korean Language online resources to see how they are currently managing the evolution of the language.
- If you're interested in the North-South linguistic divide, look into the Gyeoreomal Keunsajeon project—it's a joint effort (though often paused) to create a unified dictionary for both Koreas.
