Hangul syllable Calb

찳 is one Hangul syllable block, not an emoji. Its component letters, called jamo, are ᄎ (initial ㅊ), ᅡ (vowel ㅏ), and ᆲ (compound final ㄹㅂ). Together they form one block; ㄹㅂ sits at the bottom, not as a second syllable. “Calb” is the Unicode label for this pattern, not a translation.

Hangul was designed to write Korean more directly: Chinese characters did not fit Korean speech well, and the new script was intended to be easier to learn. A 1443 record names Hunminjeongeum; its explanatory guide, also called Hunminjeongeum, was published in 1446 and describes how the letters build syllables.

The system’s name, Hangeul, became common in the early 1910s and was widely used by 1928. That names the writing system’s later public history; it does not give this block a special period meaning.

How do I type 찳?

Use a Korean IME and enter the components in order. A Korean IME (input method) combines ㅊ, ㅏ, ㄹ, then ㅂ into 찳. The equivalent decomposed jamo sequence is 찳; Unicode’s NFC normalization form can combine those letters into the precomposed block.

Why does 찳 look different in fonts?

Hangul fonts vary the layout inside the same square cell. A font can shift a component’s placement, shape, and size, especially in the crowded final cluster. That changes the block’s appearance, not its letters or identity.
