8 Korean Experts Reveal the Biggest Mistakes Students Make When Learning Korean

Imagine this: You’ve just stepped off the plane after coming to Korea to ramp up your Korean skills in a short span of time. You have access to Korean speakers everywhere, and you have as much time as you need.

Challenge: How do you go about learning Korean in the most efficient way possible?

90 day korean

Time to learn Korean!

It may seem like an obvious answer: study hard and get lots of practice of course! Right? But if you followed the advice of most, it probably wouldn’t take you as far as you’d hoped.

The internet is filled with lots of misguided advice on language learning. A lot of the mistakes you’re making are most likely blind ones that Koreans are too kind to point out. Sometimes you just need to cut straight through the clutter and go straight to the source in order to get genuine advice.

With this in mind, we got in touch with some of the world’s leading Korean scholars, speakers, authors, bloggers and television stars and asked them the question:

What are the most common mistakes students make when learning Korean? (OR what are the biggest misconceptions people have about the Korean language)?”

We simply wanted to know which blunders students should avoid so they can cut down their learning curve and learn Korean in the most efficient manner possible.

Time to bring in the experts:



“The most common mistake I see from those who are learning Korean is the improper conjugation of noun modifying verbs and adjectives. Adjectives that modify a noun, without reference to tense, should end with ㄴ where as verbs should end with 는. Some people confuse this as the past-tense verbal modification of a noun would which to ㄴ as well. Consequently, a lot of people wind up conjugating their verbs, on accident, like adjectives and conjugating their adjectives like nouns. It is not a problem of understanding – Koreans will not correct you on this. However, it is a very evident error and speakers who do not properly conjugate will be viewed as not having good Korean.

For example, I have heard many people use the word 필요하다 the wrong way. They would say 필요하는 정보 instead of 필요한 정보. Much less often do I hear the case of conjugating a verb like an adjective such as 원한 정보 instead of 원하는 정보. However, it is this type of small error that I hear the most often and tends to make speakers sound like they are struggling with the language, when they’re really not having much difficulty. Many advanced speakers also make this mistake. I believe to a Korean it would sound much the same as dropping and misusing “the”, “a”, “an” etc. does to us in English.”

“One of the biggest mistakes most people make is formality levels. Most learners use very formal Korean (ex: -입니까? / 입니다) when they first start learning, while no one in Korea really speaks like that on a regular basis. This is because Korean teachers want students to learn the most respectful levels first, which is always safer than being too casual of course. :)”

“I think there are 3 common mistakes that Korean learners make. One is word order – most beginners are fine constructing short, simple sentences, but as sentences get longer the word order becomes more important. Another is properly using particles – specifically the topic marker and subject marker, but also knowing what particles to use with each grammar form. And above all, the most important mistake is using politeness levels – knowing when to use casual speech, when to not, and when to use honorifics. Fortunately, with practice and good lessons, anyone can pass these hurdles.”

“Thinking that if they go to Korea for a couple years to teach English, they will master Korean, when in fact teaching English in Korea and learning Korean to a high level are mutually incompatible objectives. English language education is the enemy if one really wants to master Korean. Second common mistake: thinking that Chinese characters are irrelevant to mastering Korean to a high level.”

Why to Follow Dr. King

Ross King received his PhD in Linguistics from Harvard University and his BA from Yale University (Japanese and Korean) before taking on his current positions as a Professor and Head of the Asian Studies Department at the University of British Columbia and founder and Dean emeritus of the Korean Language Village at Concordia Language Villages.

“Since we make many graphics with simple vocabulary words, one of the biggest misconceptions we see involves the use of the romanization of Korean words. People often ask us to include it within our posts. While it can be helpful at times (and we usually include the romanization in all of our graphics), we try to stress often that the pronunciation of Korean words would be much better by learning how to read the Hangul alphabet and becoming familiar with it. But a lot of people are intimidated by it.”

Why to Follow Dom & Hyo

“On the first day of every Korean elementary class, I ask questions regarding students’ perception of Korean. Most students assume that Korean people use Chinese characters for writing. They are not aware of the existence of the Korean writing system, Hankul, which is a scientific alphabet based on the phonological analysis of Korean sound patterns. Once they learn the Korean alphabet, they are amazed by how easy it is to read.

Why to Follow Dr. Daniel

Dr. Jiyoung Daniel (B.A., PhD in Linguistics) is a Korean Professor at the University of North Georgia, where she teaches all different levels of Korean in addition to specialized classes.

“I think the most common mistakes students make come early in learning the Korean language. We naturally take what we know about our mother tongue or what we’ve been taught about other languages and apply it across the board. Korean, as well as some other Asian languages, are unique in that the tactics going into learning them are quite different from other language families. Easy concepts like learning conjugation tables (I am, you are, she is, etc.) or numbers are simply not the same in Korean as in other languages. However, if students can wrap their minds around these new grammar concepts, they will have a much easier route in mastering the Korean language.”

Why to Follow Brian Van Hise

One of the most widespread misunderstandings with respect to Hangul would be that Hangul is phonetic, i.e. it matches the sounds that are represented. Certainly Hangul is more phonetic than English orthography is. However, it is much less phonetic compared to Spanish or German spelling. For example, 독립, which means independence, is pronounced /동닙/. This is because the current Hangul orthography is based on the principle that morphemes, the smallest meaning-bearing units, should retain their shape. Then is it hard to learn Hangul orthography? It could be. However, actually the current principle makes reading much easier.”

Why to Follow Kyubyong Park

So that brings us back to the imaginary scenario where we’re first hopping off the plane in Korea. 24 hours before you boarded the plane, you probably had a picture of how things would pan out in your head.

But once you stepped off that plane and you were a month into your studies, reality sunk in.

With these tips from the experts, you can now prepare yourself and gain a competitive advantage. Factor in the most common mistakes as you go about your studies and speak Korean like the pros from 비정상 회담.

However, be prepared to face certain obstacles on your Korean language learning journey. Doctor Ross King warned that “teaching English in Korea and learning Korean to a high level are mutually incompatible objectives.”

Perhaps that’s why Tyler Rasch – subjectively the best Korean speaker out of the group of foreign men from the hit TV show 비정상 회담.  — advises that you come in with clear expectations about Korean practice in Korea.

As Tyler advises:

“A quick comment on learning Korean in Korea. It’s probably the best way to do it. However, the difficulty is maintaining motivation and persevering through the largest obstacle to learning – Koreans’ emphatic and persistent use of English. Mostly, they will use it for one of two reasons. As many folks tend to notice, Koreans often insist on speaking English with foreigners in order to practice (note there used to be articles in Korean newspapers in the late nineties insisting on Koreans trying to practice with foreigners, that culture still remains). However, stronger and more difficult to overcome is the second reason for their persistent English use – politesse. They consider speaking English to foreigners to be – and often justify their persistence of English when criticized for overuse as – an attempt to be considerate for the interlocutor given that most foreigners will not understand Korean. So, it can be very difficult to get around persistent English speakers politely. However, I would recommend being equally persistent with Korean, lots of smiling, and perhaps the occasional direct comment about wanting to learn Korean – not about their overuse of English.”

Coming from a man who learned Korean in Korea himself, we think we’ll take his advice!
