Hangul syllable Pyaj

It joins a consonant, a vowel, and a closing consonant in one block.

The parts are Hangul’s building-block letters, called jamo. Here ㅍ is a p with a strong puff of air, ㅑ sounds like “ya,” and final ㅈ closes like an unreleased t. The block supplies a syllable sound; the surrounding Korean word supplies its meaning.

Why does 퍚 form a block?

It follows Hangul’s rule of arranging letters into one block per syllable.

Hangul is the Korean alphabet. Its development and explanation span 1443–1446, creating a writing system shaped around Korean speech and intended to make reading and writing more accessible than reliance on Chinese characters. The accompanying explanatory book, Hunminjeongeum, introduced the letters and showed how they form syllables.
