裂痕
liè hén · HSK 7
crack
裂 split + 痕 scar-mark = the scar a split leaves behind: a crack
裂 means to split or rend; 痕 is a mark, trace, or scar (the 痕 in 伤痕 wound-scar). Together: the lingering mark left by a split — a crack or fissure.
裂 — 列 (liè, phonetic) + 衣 (clothing)
A semantic-phonetic compound: 衣 'clothing' gives the meaning and 列 supplies the sound. The original sense was tearing or splitting cloth, which broadened to 'split, crack, rupture' in general. The 衣 component is written split around 列 rather than on the side.
