Curious Facts / Culture
Why does Hangeul group letters into blocks?
Look inside a familiar block to find its consonants and vowels.
Take 가 and 간 apart
The block 가 contains ㄱ and ㅏ. Adding the final consonant ㄴ within the same syllable gives 간. A syllable does not always have a final consonant.
A whole block and the letters inside it are different units. Hangeul letters represent sounds and are grouped into syllable blocks when written.
A position can be filled without a consonant sound
In 우유, the initial ㅇ in both 우 and 유 has no consonant sound. It fills the initial position before the vowel. This does not mean that ㅇ is silent in the final position too.

Scope of this fact
- This explains the basic structure of modern Hangeul, not total character counts or comparisons of writing-system superiority.
- The 가 and 간 diagram uses original examples. The silent-ㅇ explanation concerns its initial position in 우유, not final ㅇ.
