损伤 (sǔn shāng) is a formal verb meaning 'to damage, harm, or injure', often applied to body parts, structures, or abstract things like reputation. It differs from 损坏 (damage to objects) and 损害 (harm to interests/rights), and is more physical than 伤害 (hurt feelings/health). It is not used for financial loss (损失, 亏损).
