破損
はそん · hason · JLPT N1 · noun
damage
🔨 破 = break + 損 = loss, so 破損 = break + loss = damage
Both kanji appear in 破損 for physical harm to objects. 破 covers tearing or cracking, and 損 covers loss or harm, so the pair means something broken and reduced in value.
破 — stone 石 + skin/hide 皮
破 is a semantic-phonetic compound: 石 (stone) gives the meaning 'to break, smash,' since stones were used to crack things, while 皮 (pí) supplies the sound. The original sense of breaking stone broadened to mean 'broken,' 'damaged,' or 'to defeat.'
