Hangul groups letters into syllable blocks
Hangul was created in 1443; its guidebook, Hunminjeongeum, appeared in 1446. Earlier systems—Idu, Gugyeol, and Hyangchal—adapted Chinese characters to write Korean sounds or grammar. Hangul letters form syllable blocks.
Fonts may shift letters within the block.
Neutral syllable; the word sets the tone.
