What 촁 means
It preserves a historical Korean reading of 妻 (“wife”).
An early-15th-century Korean word list for interpreting Chinese gives 妻 a reading entry written 쳐(촁). This records a Hangul syllable used to read a Chinese character; it does not establish 촁 as a standalone modern Korean word.
Hangul, the Korean alphabet, appears in historical records in 1443; detailed rules for its letters were published in 1446 to make Korean writing easier to learn and use. In modern Korean, 妻 is read as 처. 촁 is useful when reading or transcribing the older spelling.
Why is 촁 written as a block?
It combines three Hangul letters in one square syllable cell.
Its decomposed letters are ᄎ + ᅨ + ᆼ: ㅊ starts the syllable, ㅖ is its vowel, and ㅇ ends it. A Korean input method joins these parts into the precomposed block 촁.
Hangul syllables fit square cells. A font may shift or reshape the letters within that cell, but the character remains 촁.
A historical or linguistic spelling, useful when working with the older Korean record.
In a modern Korean sentence, don't assume 촁 means “wife”; the reading is 처.
