Hangul Syllable Cwegg

It is a Hangul syllable, not a word with its own definition. Its Unicode decomposition is ᄎ + ᅰ + ᆩ: an initial consonant, a vowel, and a final consonant. Korean keyboard labels may show the corresponding compatibility forms ㅊ, ㅞ, and ㄲ. Those letters explain how the syllable is assembled; the surrounding Korean word or name supplies its meaning.

Where does its syllable structure come from?

It follows Hangul’s regular syllable-building system. Hangul, the Korean alphabet, was developed in the fifteenth century to represent Korean speech with its own letters arranged into syllable blocks. Earlier formal writing relied heavily on Classical Chinese and Idu, a way of using Chinese characters to write Korean. A unified spelling proposal in 1933 became a basis for modern Korean spelling. Those dates describe the writing system and its spelling standard.

How can I type 췎?

A Korean IME joins the letters as you type. An IME is input software that composes Hangul letters into syllables. Enter initial ㅊ, form the vowel ㅞ from ㅜ + ㅔ, then add final ㄲ. Some input paths leave the jamo separate; Unicode’s NFC normalization, a rule for joining equivalent text sequences, can turn 췎 into 췎.
