This cheat sheet covers the Hangul alphabet, the Korean writing system used to read and write Korean. Students need it because Hangul is built from letters that combine into syllable blocks, not from letters written in a straight line like English. A clear reference helps students recognize consonants, vowels, and final sounds quickly while practicing pronunciation.
Key Facts
- Hangul has 14 basic consonants: ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅊ, ㅋ, ㅌ, ㅍ, and ㅎ.
- Hangul has 10 basic vowels: ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, and ㅣ.
- A Korean syllable block is built as consonant plus vowel, or consonant plus vowel plus final consonant.
- The letter ㅇ is silent at the beginning of a syllable, as in 아, but sounds like ng at the end, as in 강.
- Horizontal vowels such as ㅗ, ㅛ, ㅜ, ㅠ, and ㅡ are usually placed under the first consonant in a syllable block.
- Vertical vowels such as ㅏ, ㅑ, ㅓ, ㅕ, and ㅣ are usually placed to the right of the first consonant in a syllable block.
- A final consonant at the bottom of a syllable block is called 받침, and it often changes how the syllable is pronounced.
- Romanization is a pronunciation guide, but reading Hangul directly is more accurate than relying on English letters.
Vocabulary
- Hangul
- Hangul is the Korean alphabet made of letters that combine into square syllable blocks.
- Consonant
- A consonant is a speech sound made by partly or fully blocking airflow, such as ㄱ, ㄴ, or ㅁ.
- Vowel
- A vowel is a speech sound made with open airflow, such as ㅏ, ㅓ, or ㅣ.
- Syllable block
- A syllable block is one written Korean unit that contains at least one consonant and one vowel.
- Batchim
- Batchim is the final consonant written at the bottom of a Korean syllable block.
- Romanization
- Romanization is the use of Latin letters to show an approximate pronunciation of Korean words.
Common Mistakes to Avoid
- Reading Hangul letters as if they always match English sounds is wrong because Korean sounds do not map perfectly to English letters.
- Forgetting that ㅇ is silent at the beginning is wrong because 아 is read a, not nga.
- Writing vowels in the wrong position is wrong because vertical vowels go to the right of the first consonant while horizontal vowels go below it.
- Ignoring batchim is wrong because a final consonant can change both the sound and meaning of a word.
- Depending only on romanization is wrong because romanized spellings can hide important Korean sound differences.

Understanding Hangul Alphabet & Pronunciation
The shape of a block gives useful clues before you know the word. Start by finding the first consonant, then see whether the vowel sits beside it or below it. Read the parts in that order.
For example, the block 한 contains ㅎ, ㅏ, and ㄴ. Its sound is close to han. A block is one spoken beat, so do not try to pause between its letters.
Reading one block at a time helps your eyes and voice stay together. As words become longer, scan from block to block rather than treating the whole word as a picture.
Korean consonants do not always match one fixed English sound. ㄱ can sound closer to g or k depending on its position and nearby sounds. ㄷ, ㅂ, and ㅈ work in similar ways.
Korean also has plain, tense, and aspirated consonants. Tense consonants are written as doubled forms such as ㄲ or ㅆ.
They are produced with a tighter, sharper start. Aspirated consonants such as ㅋ, ㅌ, ㅍ, and ㅊ have a noticeable puff of air. Hold a hand in front of your mouth when practicing.
You can feel more air for an aspirated sound. This physical check is often more useful than trying to copy an English spelling.
Final consonants need extra attention because Korean usually stops them cleanly. At the end of a block, several different letters may be heard as a short k, t, p, n, m, ng, or l type sound. The sound is often unreleased, meaning the mouth closes but does not add a strong burst.
This can feel unfamiliar to English speakers. Pronunciation can change again when the next block begins with a vowel. A final sound may move smoothly into that next block.
Other neighboring sounds can influence each other. These changes are regular patterns, not random exceptions, so listen for them in whole words rather than practicing every block alone.
Vowels deserve slow practice because some pairs are difficult for English speakers to hear. The sounds written with ㅓ and ㅗ, or ㅡ and ㅜ, use different tongue and lip positions. Watch whether your lips round, spread, or stay relaxed.
Record yourself saying short pairs, then compare your sound with a reliable Korean audio source. Romanized spellings can help identify a word at first, but they can hide these differences. English readers may give a romanized vowel the wrong sound without noticing.
In class, focus on reading the actual blocks, listening closely, and repeating short phrases with natural rhythm. Accuracy grows through many brief readings, especially with names, signs, song titles, menus, and simple messages.
