Hangul syllable Jjuss

It is a Korean syllable, usually read in the context of a word.

The block is built from ㅉ + ㅜ + ㅆ. In a Korean word, the surrounding syllables supply the word's meaning; alone, 쭜 usually reads as a fragment rather than a complete message.

Use a Korean IME and enter its three jamo in order.

Switch a Korean keyboard or input method editor (IME) to Hangul, then enter ㅉ, ㅜ, and ㅆ in order.

Unicode's three-part breakdown is ᄍ + ᅮ + ᆻ: an initial consonant, vowel, and final consonant. A Korean IME combines these jamo (Hangul letters) into one syllable block; if they remain three separate characters, the input method left the syllable uncomposed.

When did Hangul begin, and why?

Hangul was developed in the 15th century to write Korean more directly.

Hangul's earliest documentary trail reaches late 1443, when the script was developed. The 1446 Hunminjeongeum manuscript, a document introducing the new alphabet, records its presentation, explanations, and examples. The script was designed to represent Korean more directly and help people without education in Chinese characters read and write.

Before Hangul, Korean writing used Chinese characters and methods that adapted them to Korean, including Idu, Gugyeol, and Hyangchal. A proposed influence from the square-shaped Phags-pa script remains debated, not established parentage. During Hangul's early centuries, elites often regarded it as an inferior vernacular script, while women, commoners, religious translators, and popular fiction used it. By the late 19th and early 20th centuries, it was increasingly presented as a national script, and the name Hangul became widespread.
