Learn Hangul
The Korean Alphabet
24 letters. Logical design. You can read Korean within hours.
King Sejong created Hangul in 1443 so that anyone could learn to read - no matter their background. It was designed to be simple, and it is.

Why Hangul is unusually systematic
A small alphabet with a deliberately designed structure
King Sejong created the new Korean alphabet in 1443. Hunminjeongeum, the work that presented and explained the writing system, was promulgated in 1446. The project was intended to make reading and writing Korean much more accessible than relying on Classical Chinese writing.
Modern Hangul uses 24 basic letters: 14 consonants and 10 vowels. Those letters combine into square-looking syllable blocks, so you learn a compact alphabet and a set of combination rules rather than memorizing thousands of independent characters.
The original design used five basic consonant shapes—ㄱ, ㄴ, ㅁ, ㅅ, ㅇ—linked to articulatory organs or positions, with related consonants developed from those shapes. The traditional vowel design was built from three symbolic elements representing heaven, earth, and a person; the modern letterforms preserve that systematic visual logic.
That structure makes Hangul approachable, but reading comfortably still takes practice. Many beginners can learn the letters and start decoding simple syllable blocks in a few focused sessions; faster, automatic reading develops through repeated exposure.
The 5 original base consonant shapes
Learn the design logic before the related consonants
The Hunminjeongeum describes five foundational consonant shapes: ㄱ, ㄴ, ㅁ, ㅅ, and ㅇ. They are associated with places or organs of articulation, and several other consonant letters were formed by modifying these base shapes.
One of the five original base shapes, associated with the back of the tongue. Its sound varies by position and is only approximately represented by English g/k.
One of the five original base shapes, associated with the tongue touching the upper gum area. Usually similar to English n.
One of the five original base shapes, representing the mouth/lips. Usually similar to English m.
One of the five original base shapes, traditionally associated with the teeth. Its pronunciation changes before some vowels, so English s is only an approximation.
One of the five original base shapes. It is silent at the start of a syllable and has an ng sound in final position.
The remaining basic consonants
Related shapes, added strokes, and distinct sound contrasts
The other modern basic consonants fit the same visual system, but it is more accurate than saying every letter is simply “a basic consonant plus one stroke.” For example, ㄴ relates visually to ㄷ and ㅌ, ㄱ to ㅋ, ㅁ to ㅂ and ㅍ, and ㅅ to ㅈ and ㅊ. Learn the sound contrasts by listening as well as by memorizing the shapes.
The doubled tense consonants ㄲ, ㄸ, ㅃ, ㅆ, and ㅉ are an additional set built from basic consonant letters; they are not part of the 14 basic consonants counted here.
An unaspirated stop whose sound depends on position and context. Romanization d/t is a guide, not an English sound match.
An unaspirated bilabial stop. It can sound closer to English b or p depending on position and context.
An unaspirated affricate. Compare it directly with aspirated ㅊ and tense ㅉ rather than relying on English j alone.
The aspirated counterpart in the ㅈ/ㅊ contrast. Listen for the stronger burst of air compared with ㅈ.
Aspirated k-like consonant. Compare ㄱ, ㅋ, and ㄲ as a three-way Korean contrast.
Aspirated t-like consonant. Compare ㄷ, ㅌ, and ㄸ by listening to Korean examples.
Aspirated p-like consonant. Compare ㅂ, ㅍ, and ㅃ rather than mapping them directly to English letters.
Usually h-like, but it also interacts with neighboring consonants and can affect aspiration in connected speech.
Often a light flap between vowels and more l-like in final position. Neither English r nor l is an exact match in every context.
The 10 basic vowels
Built from vertical and horizontal lines
Korean vowels are constructed from combinations of a vertical line (ㅣ), a horizontal line (ㅡ), and a short stroke. The short stroke's position (left/right or above/below) determines the letter.
Vertical vowels (ㅏ, ㅓ, ㅑ, ㅕ, ㅣ) are written to the right of the consonant. Horizontal vowels (ㅗ, ㅜ, ㅛ, ㅠ, ㅡ) are written below the consonant.
An open a-like vowel, commonly approximated by the vowel in “father.” Listen to Korean examples for the target sound.
Romanized eo. It has no exact English equivalent across accents, so learn it from Korean audio rather than reading “eo” literally.
A rounded o vowel. Keep it distinct from ㅜ and learn the Korean target from audio.
A rounded u-like vowel, often approximated by “oo” in English.
No close English equivalent. Keep the lips relatively unrounded and learn the sound from Korean audio.
An i vowel, close to “ee” in many English words.
The y-glide counterpart of ㅏ.
The y-glide counterpart of ㅓ; avoid reading the romanization as two English vowels.
The y-glide counterpart of ㅗ.
The y-glide counterpart of ㅜ.
How syllable blocks work
The key insight that makes everything click
Instead of placing every letter along one horizontal line, Hangul arranges letters into syllable blocks. Each written block represents one syllable while still being made from individual consonant and vowel letters.
The block layout changes with the vowel shape and whether there is a final consonant (받침). Start by recognizing the initial consonant + vowel structure, then add final consonants.
Practice
Read real Korean words
Use the letters in actual words
Once you know the basic letters and block structure, start reading short real words. Some words will not sound exactly like letter-by-letter romanization because Korean has regular sound-change rules; the goal here is first to recognize the written blocks.
Practice
Common mistakes to avoid
These trip up almost every beginner. Knowing them upfront saves weeks of confusion.
Relying on romanization
Romanization is useful as a temporary label, but Korean sounds do not map 1:1 to English letters. For example, ㄷ is written d/t in Revised Romanization because its realization changes by position and context. Pair Hangul with Korean audio instead of treating the Latin letters as pronunciation instructions.
Thinking Hangul has thousands of letters
Modern Hangul has 24 basic letters. They combine into many possible syllable blocks, but learners do not memorize every block as an independent character; they learn the letters and block-building rules.
Treating compound vowels as simple English sound sums
Compound vowel spellings are systematically related to basic vowels, but modern pronunciation does not always equal a neat sum of two English-like sounds. Learn the spelling pattern, then confirm the actual Korean pronunciation with audio.
Never writing the letters yourself
You do not need long handwriting drills to type Korean, but brief handwriting practice can reinforce stroke direction, letter recognition, and the structure of syllable blocks.

Frequently asked questions
How long does it take to learn Hangul?
Many beginners can learn the 24 basic letters and begin decoding simple syllable blocks in a few focused study sessions. Reading comfortably and automatically takes longer because you also need practice with batchim, compound vowels, sound changes, and real vocabulary. Treat “learn Hangul in a day” as a starting milestone, not a fluency promise.
Is Hangul an alphabet or a syllabary?
Hangul is an alphabetic writing system: its consonant and vowel letters represent smaller sound units. The letters are arranged visually into syllable blocks, which is why the writing can look syllabic even though the underlying units are alphabetic. It is also often described as featural because parts of the letter design encode systematic phonetic relationships.
Do I need to learn Hangul before studying Korean?
Learn Hangul very early, but you do not have to postpone every spoken phrase until you finish it. A good beginner approach is to learn the alphabet alongside basic greetings and listening, then phase out romanization quickly so pronunciation, spelling, dictionary use, and grammar study are based on Korean text.
How does Duolingo teach Hangul now?
Duolingo's July 2026 Korean update added a dedicated Hangeul tab, alphabet teaching sessions on the path, and optional sentence transliteration that learners can turn on or off. Letter-level teaching still helps many learners: syllable-first practice can leave the 24-letter system unclear, and romanization is a weak guide to Korean sounds.
What about double consonants and compound vowels?
The doubled consonants ㄲ, ㄸ, ㅃ, ㅆ, and ㅉ are tense (fortis) consonants that contrast with the plain and aspirated series. Do not learn them as simply “more force”; listen to minimal contrasts and timing. Compound vowels such as ㅘ and ㅝ have systematic spellings, but their modern pronunciation should still be learned from Korean audio rather than English letter-by-letter approximations.
