The quick answer

Hangul is an alphabet arranged in syllable blocks. Each block starts with a consonant position, includes a vowel, and may end with one or more final consonants.

Start with a sound, not a whole word

A Korean word can contain several square-looking blocks. Each block represents a syllable, not a whole word or a picture. The word 한글 has two blocks: 한 and 글. Looking for the letters inside a block makes a long word much less intimidating. Read the blocks from left to right, just as you read English words.

Build your first block

Choose ㄱ and add ㅏ. You get 가. The upright vowel goes to the right of the first consonant. Now choose ㄴ and add ㅗ. You get 노. This vowel sits below the consonant. The layout changes to make one balanced block, but you still read the starting consonant before its vowel. Our Hangul studio lets you try these combinations without needing a Korean keyboard.

Give a vowel a place to start

A syllable needs a starting consonant position even when you hear no consonant there. The letter ㅇ fills that position silently: ㅇ + ㅏ = 아. At the bottom of a block, however, ㅇ represents an “ng” sound. This is a good reminder that the position of a letter matters. An English spelling is only a rough guide to the Korean sound.

Add a final consonant

In 한, ㅎ starts the block, ㅏ supplies the vowel, and ㄴ sits underneath. That last position is called 받침, commonly written batchim in English. Do not add an extra vowel after the final consonant. Some final sounds change when connected to the next syllable, so begin with clear examples before trying to predict every pronunciation.

Try it without looking

Build 가, then 아, then 하 in the studio. Say each one and notice which letter changes. Next, compare 고 with 구. Finish by looking at 한글 and finding the vowel in each block. This small task gives you a reusable reading strategy. Modern Hangul uses 19 initial consonants and 21 vowels. A syllable can use one of 27 final consonant forms (받침), whose ending sounds generally reduce to seven groups; the sound may change when the next syllable begins. You can explore the forms in the studio.

Keep these examples handy

Expression or step	Reading or meaning	How to use it
ㄱ + ㅏ	가	ga / ka, approximately
ㄴ + ㅗ	노	no
ㅇ + ㅏ	아	a
ㅎ + ㅏ + ㄴ	한	han

Your questions, answered

Is each Korean block a word?

No. A block represents a syllable. A word may contain one or several syllable blocks.

Is ㅇ always silent?

No. It is silent at the beginning of a syllable, but sounds like “ng” in the final position.
