Korean in South Korea, North Korea and the diaspora
Korean is the official language of South Korea and North Korea, and about 80 million people speak it as their first language. Larger Korean-speaking communities also live in China, the United States, Japan and Central Asia. Online courses almost always teach the standard Korean of South Korea, which is based on the speech of Seoul. North and South Korean differ mainly in vocabulary.
Most learners name one of five goals.
- They want to follow Korean dramas, films and music in the original.
- They plan an exchange semester or a degree at a Korean university.
- They want to spend a year in South Korea on a working holiday visa, which South Korea offers to young people from countries such as Australia, Canada, New Zealand and the UK.
- They work with Korean companies in electronics, cars, shipbuilding or chemicals.
- They have family or friends in Korea.
Online lessons suit Korean well, because local classes outside university towns are rare. The South Korean government promotes the language worldwide through the King Sejong Institute Foundation, which runs Sejong Institutes and online courses. In this way South Korea strengthens its cultural reach and attracts students and skilled workers.
A large part of Korean vocabulary comes from Chinese. If you already know Chinese or Japanese, you will recognise many word roots, such as hakgyo (school) or daehak (university).
The Hangul alphabet with 24 basic letters
Hangul is the Korean script. King Sejong commissioned it and proclaimed it in 1446. Hangul is an alphabet with 14 basic consonants and 10 basic vowels. Many learners can read it after a few days, because the letters follow a clear system.
The letters do not run in a line as in English. They are stacked into syllable blocks. Each block starts with a consonant, followed by a vowel and sometimes a final consonant. This final consonant is called batchim.
| Syllable block | Parts | Pronunciation | Role in the word |
|---|---|---|---|
| 한 | ㅎ + ㅏ + ㄴ | han | first syllable of Hangul |
| 글 | ㄱ + ㅡ + ㄹ | geul | script |
| 사 | ㅅ + ㅏ | sa | first syllable of saram (person) |
| 랑 | ㄹ + ㅏ + ㅇ | rang | second syllable of sarang (love) |
The shapes follow a logic. The basic consonants picture the position of tongue, lips and throat, and further consonants add extra strokes. The vowels are built from a vertical line, a horizontal line and a dot, which today is written as a short stroke.
Learn the whole of Hangul in the first week of your course and then drop romanisation. Romanised Korean renders the sounds only roughly, and in South Korea you rarely see it on signs or menus.
Three kinds of consonants and sound rules in speech
Standard Korean has no tones like Chinese. The biggest hurdle for English speakers lies in the consonants. For many sounds Korean distinguishes three kinds, where English has only two.
| Kind | Example | How to produce it |
|---|---|---|
| plain | ㄱ (g/k), ㄷ (d/t), ㅂ (b/p) | relaxed, with a light puff of air |
| aspirated | ㅋ (k), ㅌ (t), ㅍ (p) | with a strong puff of air |
| tense | ㄲ (kk), ㄸ (tt), ㅃ (pp) | with a tight throat and no puff |
Among the vowels, ㅓ (eo) and ㅗ (o) cause trouble, because both can sound like an o to English ears. The ㅡ (eu) resembles the oo in good said with spread lips.
Spoken Korean follows sound rules. A final consonant often moves into the next syllable when that syllable starts with a vowel. Other consonants adapt to their neighbours. Gamsahamnida (thank you) is spelled with the syllable hab, but you say ham. If you read only what is written, you will sound choppy.
Strong online courses record your speech and play it next to a native speaker's version. That way you hear the difference between plain, aspirated and tense sounds that English does not mark.
Speech levels, particles and verb endings in Korean
In a Korean sentence the verb comes last. Small endings on the noun, called particles, mark its role: eun or neun marks the topic, i or ga the subject, eul or reul the object. The right form depends on whether the word ends in a vowel or a consonant.
Verbs take endings for tense, politeness and sentence type, and these endings stack up. The key decision in every sentence is the speech level. It depends on the age, rank and closeness of the people talking.
| Speech level | Ending | Example for to go | Typical use |
|---|---|---|---|
| formal polite | -ㅂ니다 | gamnida | news, announcements, presentations |
| informal polite | -요 | gayo | daily life with strangers and colleagues |
| intimate (banmal) | stem without -요 | ga | friends, family, younger people |
| honorific | -시- in the verb | gaseyo | actions of elders and superiors |
Courses usually start with the informal polite -yo form, because it fits most everyday situations. You hear banmal, the intimate form, all the time in dramas. With strangers and older people, however, it sounds disrespectful.
Korean also has two number systems. Native Korean numbers count hours, age and objects, while Sino-Korean numbers cover minutes, prices and dates.
Learners who ignore speech levels early on tend to switch between polite and intimate speech without noticing. Native speakers notice at once, and it comes across as rude.
Korean in Category IV with 2,200 classroom hours
The Foreign Service Institute (FSI), the language school of the US State Department, places Korean in its hardest group, Category IV, with Japanese, Mandarin and Arabic. To reach level 3 on the ILR scale, a US government scale for confident professional use of a language, the FSI calculates 88 course weeks and 2,200 classroom hours. The figures apply to native English speakers in full-time classes of 23 hours a week.
The effort is unevenly spread. The script comes very quickly. Grammar with particles and endings becomes dense from intermediate level on, and the vocabulary has almost nothing in common with English, apart from loanwords such as keompyuteo (computer).
With three hours of class a week alongside a job, you collect about 130 classroom hours a year. That is usually enough for simple everyday conversation and basic reading after one year. For a degree taught in Korean, where universities usually ask for at least level 3 of the official TOPIK exam, plan for several years or an intensive phase.
6 types of online Korean courses and their costs
Online Korean courses differ in how much you speak and how thoroughly they practise pronunciation and speech levels. The prices are rough guide values for 2026 and depend on the provider and teacher.
| Course type | Suits | Limit | Guide price 2026 |
|---|---|---|---|
| Live one-to-one lessons by video | pronunciation, speech levels, own pace | little structure without a syllabus | approx. $15-45 per hour |
| Live group class | fixed times, textbook progression | little speaking time per person | approx. $10-25 per hour |
| Sejong Institute or university course | structured progression by level | fixed term dates | free to approx. $300 |
| App | daily Hangul and vocabulary | almost no free speaking | free to approx. $15 per month |
| AI tutor | speaking practice without appointments | may mix up speech levels | approx. $10-30 per month |
| TOPIK preparation course | exam format, writing tasks | narrowly focused on the test | approx. $150-500 per course |
The TOPIK is South Korea's official six-level Korean exam. An AI tutor is a program that talks with you, scores your pronunciation with speech recognition and adapts exercises to your mistakes. For work there is business Korean with formal speech levels, emails and meetings.
- ✓Native-speaker teachers are easy to reach online.
- ✓Dramas and music supply daily listening practice at natural speed.
- ✓Recordings let you replay the three kinds of consonants as often as you need.
- ✗Korea is UTC+9 all year, which is 13 to 17 hours ahead of most of North America.
- ✗Without a teacher, many learners copy the intimate speech level from dramas.
- ✗Without fixed lessons, many self-learners lose their routine.
TOPIK I and TOPIK II with score thresholds for six levels
The TOPIK (Test of Proficiency in Korean) is South Korea's official Korean exam. It is run by the National Institute for International Education (NIIED), an agency of the South Korean Ministry of Education. NIIED also manages the government's Global Korea Scholarship, and Korean universities use the TOPIK to admit international students.
The exam has two parts. TOPIK I tests listening and reading and awards levels 1 and 2. TOPIK II tests listening, reading and writing and awards levels 3 to 6. Your level follows from the total score of the paper-based test.
| Exam | Level | Score (paper-based) | Stage |
|---|---|---|---|
| TOPIK I | 1 | 80 of 200 or more | beginner |
| TOPIK I | 2 | 140 of 200 or more | beginner |
| TOPIK II | 3 | 120 of 300 or more | intermediate |
| TOPIK II | 4 | 150 of 300 or more | intermediate |
| TOPIK II | 5 | 190 of 300 or more | advanced |
| TOPIK II | 6 | 230 of 300 or more | advanced |
A TOPIK score is valid for two years from the date the results are announced. For 2026 the Ministry of Education announced six paper-based sessions, five of them also abroad, according to Korea JoongAng Daily. There are also sessions of the internet-based TOPIK (IBT), which you take on computer at a test centre and which uses its own score scale. The IBT is so far available only in Korea and a limited number of countries. A separate speaking test, TOPIK Speaking, is offered only in Korea in 2026.
Korean universities usually require at least level 3 for degrees taught in Korean, and many require level 4 for graduation. The TOPIK does not use the CEFR, the Common European Framework of Reference with its levels A1 to C2, so there is no official conversion.
Check on topik.go.kr whether your test site offers the paper or the computer version, and practise with mock tests in the matching format. Register early, because places abroad are limited.
7 questions for an online Korean course before you book
Ask these seven questions before you pay for an online Korean course.
- Does the course teach all of Hangul in the first week and then drop romanisation?
- Does the teacher practise the three kinds of consonants and the sound rules with you, rather than only testing vocabulary?
- Does the course explain from the start which speech level fits which situation?
- Is the syllabus tied to levels 1 to 6 of the TOPIK, the official Korean exam, with goals for every unit?
- Do you speak for more than half of each live lesson?
- Can you book a trial lesson, and do prepaid lessons expire?
- Does the provider explain how it stores recordings and voice data, for example under the GDPR, the EU's data protection law?
Be careful when a provider guarantees a TOPIK level within a short time or insists on a full year paid upfront. Your TOPIK result depends on your own study time.
Learning Korean with dramas and music without copying mistakes
Many learners come to Korean through dramas, films and music from South Korea. This material is a big advantage, because it provides daily listening practice at natural speed. It also has three quirks that a course should balance.
1 Lots of intimate speech
Characters in dramas often use banmal, the intimate speech level. For daily life with strangers, use the polite -yo form.
2 Regional dialects
Many dramas feature dialects, for example from Busan and the Gyeongsang region. Learn the standard Korean of Seoul first.
3 Subtitles replace listening
With English subtitles you read more than you hear. Watch familiar episodes a second time with Korean subtitles or none at all.
One proven exercise is shadowing. You hear a short line from a scene and repeat it right away at the same speed, copying stress and melody. This trains pronunciation and sound rules at the same time.
Frequently asked questions about online Korean courses
How long does it take to learn the Korean alphabet Hangul?
Many learners can read the Korean alphabet Hangul after a few days, because it has only 14 basic consonants and 10 basic vowels. The letters follow a clear system and are stacked into syllable blocks. Fluent, fast reading then takes a few weeks of practice.
How long does it take to learn Korean online to a professional level?
Learning Korean to a professional level takes about 2,200 classroom hours of full-time study, according to the US Foreign Service Institute. Korean sits in its hardest group, Category IV, with Japanese and Mandarin. With a few hours a week, plan for several years.
How many points do you need for each TOPIK level?
TOPIK levels in the paper-based test depend on the total score. In TOPIK I you need 80 of 200 points for level 1 and 140 for level 2. In TOPIK II you need, out of 300 points, 120 for level 3, 150 for level 4, 190 for level 5 and 230 for level 6.
How long is a TOPIK score valid?
A TOPIK score is valid for two years from the day the results are announced. After that, universities, authorities and scholarship providers usually no longer accept it. Time your exam to match your application.
Which TOPIK level do Korean universities require for degrees taught in Korean?
Korean universities usually require at least TOPIK level 3 for degrees taught in Korean. Many set level 4 as a graduation requirement. The exact rule is in each university's admission requirements.
Can you take the TOPIK exam online from home?
No, you cannot take the TOPIK exam from home. Besides the paper test there is the internet-based TOPIK (IBT), but you sit it on computer at a test centre. The IBT is so far available only in Korea and a limited number of countries.
How much does an online Korean course cost?
An online Korean course with a private tutor costs roughly 15 to 45 US dollars per hour in 2026, depending on the teacher and platform. Group classes are usually cheaper per hour. Apps and AI tutors cost about 10 to 30 dollars a month, and many have a free basic version.
