What 찲 means
CALM names the parts; it does not translate the block.
Hangul blocks group letters called jamo, the building pieces of the alphabet. For 찲, the Unicode labels are C + A + LM; in familiar compatibility-jamo form, that is ㅊ + ㅏ + ㄻ. The block supplies a syllable, while any word containing it supplies the meaning.
Hangeul, the Korean alphabet, was developed in 1443–1446 to make Korean easier to write. A unified spelling proposal from 1933 helped shape modern Korean spelling.
A Hangul writing unit; the word around it supplies the meaning.
Do not read CALM as the English mood word; it labels the Hangul parts.

2Can 찲 split into jamo?
Yes. Unicode can represent the same syllable as three canonical jamo, 찲, and normalization can recompose them as 찲. The familiar compatibility sequence ㅊ + ㅏ + ㄻ is a different encoded sequence.
Will 찲 look different in another font?
Yes. A font supplies the glyph drawing, so stroke details can differ while the text remains the same character.
