Hangul Syllable Sseunh

An initial consonant, vowel and final cluster make the block.

Hangul calls these alphabetic parts jamo.

Created in 1443 under King Sejong, Hangul made Korean easier to write; its 1446 guide, Hunminjeongeum, explained the rules. Before Hangul, Idu and Hyangchal adapted Chinese characters for Korean. In Joseon, Hangul appeared in letters and books while classical Chinese remained official. Korean nationalists began standardizing spelling in the late 19th century. The dates 1443 and 1446 concern Hangul and its guide, not this block's first use.
