恢复 vs 还原 (restore)

• Pinyin: huīfù / huányuán
• Formation: 恢复 + Noun (general recovery) / 还原 + Noun (exact restoration)
• Hanzi breakdown: 恢 = 忄(heart) + 灰 (ash) — heart rising from ashes; 复 = 彳(step) + 复 (return); 还 = 辶 (walk) + 不 (not); 原 = 厂 (cliff) + 泉 (spring) — the source spring

Meaning

恢复 (huīfù) and 还原 (huányuán) both mean 'to restore' or 'to return to an original state,' but they differ in scope. 恢复 covers general recovery of functions, conditions, or states, while 还原 specifically means returning something to its exact original form or composition.

恢复 is the more common and versatile word, used for recovering health (恢复健康), resuming operations (恢复营业), restoring order (恢复秩序), or getting back to a previous state. It does not require returning to the precise original condition — partial recovery counts. 还原 is more precise and technical: it implies faithfully reproducing or reverting to the exact original state. In chemistry, 还原 means 'reduction' (the opposite of oxidation). In computing and design, 还原 means 'undo' or 'revert to original.' In cultural contexts, 还原历史真相 means 'to restore the true face of history.' 还原 carries a sense of authenticity and exactness that 恢复 does not.

Examples

1. 手术后他花了三个月才恢复健康。 It took him three months to recover his health after the surgery.
2. 这部纪录片试图还原那段被遗忘的历史。 This documentary attempts to faithfully restore that forgotten period of history.
3. 受台风影响中断的航班已全面恢复。 Flights disrupted by the typhoon have fully resumed.

Origin & History

恢复 combines 恢 (expand, restore — originally meaning 'great' or 'vast') and 复 (to return, to repeat). 还原 combines 还 (to return) and 原 (original, source), literally 'return to the origin.' 还原 has been borrowed into scientific terminology as 'chemical reduction.'
