Hangul Syllable Cils

It is one Korean syllable block built from three Hangul parts.

칤 combines ㅊ as its starting consonant, ㅣ as its vowel, and ㄽ as its final cluster. The letters used to build Hangul syllable blocks are called jamo; the final consonant cluster, or batchim, sits at the bottom. “Cils” is Unicode’s technical label for this combination, not a Korean word.

Before Hangul, Korean writers adapted Chinese characters to write Korean words and grammar in methods such as Idu, Hyangchal, and Gugyeol. Hangul was designed to write Korean directly. A late 1443 record announces the new 28-letter script; the 1446 Hunminjeongeum, a book explaining its design, describes how letters form syllable blocks.

How do I type 칤?

Use Korean keyboard software to enter its parts. Enter ㅊ, ㅣ, ㄹ, then ㅅ in a Korean input method editor (IME); it combines them into 칤. If a program requires Unicode’s conjoining jamo sequence, use ᄎ + ᅵ + ᆳ.

A text field may show 칤 as separate jamo instead of one precomposed block. Unicode normalization treats that sequence and 칤 as canonically equivalent, although software may store or display the parts differently.

Why does 칤 look different?

The same syllable can have different proportions across fonts. Fonts fit the starting consonant, vowel, and final cluster into a square cell, so their shapes and spacing vary. The extra ㅅ in ㄽ belongs to the final cluster; it is part of the syllable, not punctuation.
