If you stepped off a plane in Pyongyang tomorrow, you wouldn’t need a specialized translator if you already speak Korean. You’d hear the same rhythmic flow of vowels and the familiar "annyeong" that echoes through the streets of Seoul. But within ten minutes of trying to buy a snack or asking for directions, things would get weird.
You’d realize quickly that while what language do north koreans speak is technically "Korean," the version they use is like a time capsule that has been buried, dug up, and aggressively polished with a very specific political sandpaper.
The Myth of Two Different Languages
Let’s get the big one out of the way. North and South Koreans speak the same language. It’s called Chosŏn-mal in the North and Hangung-mal in the South.
They use the same alphabet.
In the North, they call it Chosŏn-gŭl. In the South, it’s Hangul. It’s the same 15th-century phonetic masterpiece created by King Sejong the Great. If you can read a menu in a K-Town BBQ joint in New York, you can read a propaganda poster in a Kaesong subway station.
But seventy years of total isolation does something to a tongue. Think of it like British English and American English, but if the British had spent the last century trying to systematically delete every word that sounded too "American" or "French" and replaced them with "Pure British" alternatives.
Actually, it’s more intense than that.
Munhwaŏ: The "Cultured Language"
In 1966, Kim Il Sung decided the Seoul dialect was too "flabby." He didn't like the way it sounded—too many foreign influences, too much "bourgeois" Western flavor. So, he established Munhwaŏ, or "Cultured Language."
This is the official standard for what North Koreans speak today. It’s based on the Pyongyang dialect, but it’s been curated.
It’s sharp. It’s forceful.
When you hear a North Korean news anchor, that's Munhwaŏ in its most extreme form. It sounds like every sentence is being marched across a parade ground. It’s not just an accent; it’s a performance of revolutionary zeal.
The Great Vocabulary Divide
The real shock for defectors moving south—or for anyone looking at the linguistic split in 2026—isn't the grammar. It’s the words.
South Korea is a linguistic sponge. They love English loanwords (Konglish). If a South Korean wants "juice," they say juseu. If they want "ice cream," they say aiseu-keurim.
North Korea? Not so much.
They have a policy of "language purification." They take foreign concepts and try to "Korean-ize" them. It leads to some pretty creative, and honestly, quite logical descriptions:
- Ice Cream: Oureum-bolsong-ee (literally "icy frosting") or sometimes oreum-gwaja ("ice candy").
- Doughnut: Garakji-ppang ("ring bread").
- Bulb: Bul-al ("fire egg"—though this one is a bit of a linguistic legend that gets debated).
- Vegetable: In the South, it's yachae (from Chinese). In the North, it's namsae (an older, native Korean word).
Then you have the "false friends." These are the dangerous ones.
In the North, the word dongmu means "comrade" or "friend." It’s everywhere. In the South, if you call someone dongmu, people will look at you like you just walked out of a Cold War spy movie. The word has been completely scrubbed from Southern casual conversation because of its communist associations.
Even weirder? The "Octopus/Squid" flip. In the South, nakji is a small octopus and ojingeo is a squid. In certain regions of the North, the meanings are literally reversed. Imagine trying to order dinner and getting a completely different multi-limbed sea creature.
Why the Accent Sounds "Old"
Many South Koreans describe the North Korean accent as sounding "quaint" or "vintage."
It’s basically 1950s Korean.
While the South evolved with global pop culture, the North stayed still. They kept the high-pitched, staccato intonations. They didn't adopt the softer, more melodic "Seoul glide" that you hear in K-Dramas.
There's also the matter of the "Initial Sound Rule."
In the South, they don't like starting words with "n" or "r" sounds if they can help it. The surname "Lee" is written and pronounced I (ee) in the South. In the North, it’s Ri. The word for "woman" is yeoja in Seoul, but nyeoja in Pyongyang.
It makes the Northern speech sound "harder" to the ear.
The Social Hierarchy of Speech
Korean is a language of "levels." How you talk to your boss is totally different from how you talk to your toddler.

In the South, these levels have softened a bit in casual settings. In the North, they have been weaponized for the state. There are special honorifics used only for the Kim family. You don't just use high-level grammar; you use specific, "deified" vocabulary that you would never apply to a normal human being.
Interestingly, North Koreans often use the "super-polite" verb endings (hasipseo-che) much more frequently in daily life than South Koreans do. It’s a culture of intense formality and constant social positioning.
Can They Still Understand Each Other?
If you put a teenager from Pyongyang and a teenager from Seoul in a room, they could communicate.
They’d get the gist.
But they’d hit walls. The Southerner would use slang like "jonda" (cool) or mention "WiFi," and the Northerner would be lost. The Northerner would use ideological terms or old-fashioned idioms, and the Southerner would think they sounded like a grandfather from the countryside.
Studies on defectors show that the vocabulary gap is now about 30% for everyday words. For technical or medical terms? It’s closer to 60%.
A North Korean doctor and a South Korean doctor would actually struggle to perform surgery together because their names for anatomy and equipment have diverged so much.
Breaking Down the Dialects
It’s not just one "North Korean" language. The country is mountainous, and people don't move around much. This has preserved regional dialects that are actually quite distinct:

- Pyongan Dialect: The basis of the "Cultured Language." It's what you hear in the capital.
- Hamgyong Dialect: Spoken in the northeast (where most defectors come from). It’s known for being very "tough" and "strong," with a very different pitch accent.
- Hwanghae Dialect: Similar to the speech in regions just across the border in the South.
What This Means for the Future
Language is a living thing. You can't freeze it, even in a place as controlled as North Korea.
Despite the government's best efforts, "Southernisms" are leaking in. USB drives filled with K-Dramas find their way across the border. Young North Koreans are starting to pick up Southern intonations or "cool" ways of speaking in secret.
The state hates this. They’ve actually passed laws—the "Pyongyang Cultural Language Protection Act"—to crack down on anyone caught using South Korean styles of speech. They see it as a "vicious cancer" threatening their ideology.
Honestly, that’s the most fascinating part about what language do north koreans speak. It’s not just about communication. It’s a battlefield. Every time a North Korean kid accidentally says "oppa" (a Southern way for a girl to address an older male) instead of the state-sanctioned "dongji," they are technically committing a political act.
How to Lean Into the Differences
If you're interested in the nuances of the Korean language, don't just stick to the standard Seoul textbooks.
- Watch North Korean News: You can find clips of KCTV online. Listen to the "Staccato" rhythm. Notice how the pitch rises sharply at the end of sentences.
- Look for "Defector YouTube": There are many creators in the South who grew up in the North. They often do "dialect challenges" where they compare words for things like "refrigerator" or "makeup."
- Study the "Purified" Words: Learning North Korean neologisms is a great way to understand the "pure" Korean roots of words that have been replaced by English in the South.
Understanding the linguistic divide gives you a window into the North Korean mind that politics alone can't provide. It shows a people trying to hold onto a sense of "Koreanness" while the rest of the world moves at light speed.
If you're learning the language, keep a list of these "false friends." It might just save you from a very awkward conversation one day.
Next Steps for Your Linguistic Journey:
Research the Pyongyang Cultural Language Protection Act to see how the North Korean government is currently trying to "filter" South Korean slang out of the younger generation's vocabulary. You can also look up the "Univoca" app, which was designed specifically to help North Korean defectors translate South Korean "Konglish" into words they actually understand.
