• Pinyin (with tone marks): fǎnfù
• Part of Speech: Adverb / Verb
• HSK Level: HSK 4
• Concise Definition: To do something repeatedly; to relapse, fluctuate, or go back and forth.
• In a Nutshell: `反复` isn't just about doing something again. It carries the feeling of a process that isn't linear. Think of a wave moving up and down, a decision you keep reconsidering, or an illness that gets better and then worse again. It describes a cycle of repetition that often involves a change in direction or state, a “back and forth” motion, whether in action, thought, or health.

• 反 (fǎn): The core meaning is “to reverse,” “to turn over,” or “opposite.” Imagine flipping a pancake—that's a `反` action. It implies a change in direction.
• 复 (fù): This character means “to repeat,” “to return,” or “to restore.” It signifies going back to a previous state or doing something again.

By combining “turn over” (`反`) and “repeat” (`复`), the word `反复` vividly paints a picture of a non-linear process. It's not just repeating, it's “reversing and repeating,” creating the sense of going back and forth, like pacing a room while thinking or a fever that breaks and then returns.

In many Western cultures, “going back and forth” on a decision can be seen as indecisiveness. However, the process of `反复思考` (fǎnfù sīkǎo - to think over and over) is often viewed in Chinese culture as a sign of prudence, thoroughness, and responsibility. Before making a significant decision—whether in business, family, or personal life—it's considered wise to examine the issue from all angles, even if it means revisiting the same points multiple times. This connects to the cultural value of caution and stability. Rushing into a decision is seen as reckless. The act of `反复` is a tool for mitigating risk. For example, an engineer who `反复检查` (fǎnfù jiǎnchá - repeatedly checks) her work is seen as diligent and reliable. This contrasts with a “move fast and break things” mentality, highlighting a cultural preference for getting it right through careful, repeated consideration rather than correcting mistakes later.

`反复` is an incredibly common word used in various contexts, with its connotation shifting from positive to negative depending on the situation.

The most common point of confusion for learners is the difference between `反复` and `重复 (chóngfù)`.

• `反复 (fǎnfù)`: Implies a complex, back-and-forth, or fluctuating process. It often involves thought, change of state, or variation in the repetition.
  • Correct: `病情反复` (bìngqíng fǎnfù) - The illness relapsed.
  • Correct: `反复思考` (fǎnfù sīkǎo) - To think things over and over.
• `重复 (chóngfù)`: Implies simple, direct, mechanical repetition. You are doing the exact same thing again.
  • Correct: `重复这句话` (chóngfù zhè jù huà) - Repeat this sentence.
  • Correct: `这个动作重复十次` (zhège dòngzuò chóngfù shí cì) - Repeat this movement ten times.

Common Mistake: Using `重复` for a relapse.

• Incorrect: `他的病重复了。` (Tā de bìng chóngfù le.)
• Correct: `他的病反复了。` (Tā de bìng fǎnfù le.)
  • Why: An illness isn't a mechanical action you can “repeat.” It's a condition that fluctuates, making `反复` the correct choice.

Common Mistake: Using `反复` as a verb to mean “to repeat an object.”

• Incorrect: `请你反复你的话。` (Qǐng nǐ fǎnfù nǐ de huà.)
• Correct: `请你重复你的话。` (Qǐng nǐ chóngfù nǐ de huà.)
  • Why: When asking someone to say the exact same words again, `重复` is the right verb. `反复` would be used as an adverb, like `他反复地说着同样的话` (He kept saying the same thing over and over).

• 重复 (chóngfù) - The closest synonym, but refers to simple, mechanical repetition without the “back-and-forth” nuance.
• 再三 (zàisān) - An adverb meaning “again and again,” often used to emphasize repeated exhortations, requests, or warnings. (e.g., `我再三告诉他要注意安全` - I told him again and again to be careful).
• 一再 (yīzài) - An adverb also meaning “repeatedly,” similar to `再三` but often implying that the repeated action is contrary to expectations or wishes.
• 纠结 (jiūjié) - To be entangled or conflicted. This is the feeling one often has when `反复思考` (thinking back and forth).
• 波动 (bōdòng) - To fluctuate or undulate. A condition that `反复` (relapses) often shows `波动` (fluctuations).
• 思考 (sīkǎo) - To think or ponder. It is frequently paired with `反复` to mean “to think over repeatedly.”
• 检查 (jiǎnchá) - To check or inspect. Paired with `反复` to mean “to check thoroughly and repeatedly.”
