愈合

• Pinyin: yù hé
• Hanzi breakdown: 愈 = 俞 (a character linked to healing/recovery — originally associated with medical restoration); 合 = 亼 + 口 (assembly + opening — to close, to come together)

Meaning

To heal; to close over; to mend. Used specifically of wounds, cuts, or fractures — both physical and, metaphorically, psychological or social.

Primarily a medical/biological term for wound healing. Common phrases: 伤口愈合 (wound healing), 骨折愈合 (fracture healing), 愈合过程 (healing process). Used metaphorically for the healing of historical trauma, social divisions, or emotional wounds. More specific than 恢复 (recovery) or 好转 (improvement) in medical contexts.

Examples

2. 战后数十年，官方推动和解，但族群隔阂与集体创伤始终没有真正愈合。 Decades after the war, the government promoted reconciliation, but ethnic divides and collective trauma never truly healed.
3. 医生叮嘱伤口保持干燥清洁，因为潮湿会滋生细菌，延缓创面愈合并增加感染风险。 The doctor told the patient to keep the wound dry and clean, because moisture can breed bacteria, delay wound healing, and raise the risk of infection.
