Hangul syllable Kebs

It is one Hangul syllable block, not a full message.

Hangul is the writing system for Korean: consonant and vowel letters are arranged into square syllable blocks. This Hangul block represents one syllable, but a syllable does not necessarily make a complete word.

Hangul’s first official record dates to December 1443. In 1446, Hunminjeongeum, a book, explained the script’s purpose: it was designed for broad use. Joseon adopted Hangul as its official script in 1894; under Japanese rule, its use was banned in 1910 while study continued. Phags-pa, an older square-form script, was considered during Hangul’s creation.
