次 vs 回 (cì vs huí): two verbal classifiers for occurrences
次 and 回 both mean “time(s)” as an occurrence, but they differ in register: 次 is neutral and used in both formal and written contexts, while 回 is more colloquial and appears mainly in spoken or informal Chinese. The choice depends on style and genre, with 次 being the safer default for general use.
次 and 回 are both classifiers used to count the number of times an action occurs. 次 is the standard, neutral classifier; it is appropriate in all styles, from casual speech to formal writing. 回 is more colloquial and tends to be used in spoken narratives or informal contexts. While they are often interchangeable in everyday conversation, fixed expressions and formal registers strongly prefer 次.
When to use each
Use 次 as the default classifier for occurrences. It is neutral in register and works in both formal and informal contexts. It appears in fixed phrases like 第一次 (first time), 每次 (every time), and 多次 (many times). In writing and official language, 次 is the expected choice.
次 is purely a classifier and carries no extra semantic nuance. It is the most frequent and versatile word for counting occurrences.
Use 回 primarily in spoken or informal contexts when counting times. It is common in casual conversation, such as 有一回 (once) and 好几回 (several times). It can also appear in set expressions like 这回事 (this time) and 头一回 (the first time), but these are more colloquial.
回 originally means 'to return,' and as a classifier it retains a slight sense of 'turn' or 'occasion.' This nuance makes it feel more narrative or conversational than 次.

Examples
- 次这是我第一次来北京。Zhè shì wǒ dì yī cì lái běi jīng.This is my first time coming to Beijing.Fixed expression 第一次 always uses 次.
- 次我去过三次上海。Wǒ qù guò sān cì shàng hǎi.I have been to Shanghai three times.Neutral counting — 次 is natural.
- 回有一回，我在路上遇到他。Yǒu yì huí, wǒ zài lù shang yù dào tā.One time, I ran into him on the road.Colloquial narrative — 回 fits the informal spoken style.
- 回他来过好几回了。Tā lái guò hǎo jǐ huí le.He has come several times already.Casual speech — 回 sounds natural; 次 would be slightly formal.
- 次他多次提醒我注意安全。Tā duō cì tí xǐng wǒ zhù yì ān quán.He reminded me many times to pay attention to safety.Formal context — 次 is appropriate; 回 would be too informal.
- 回这回事可不一样。Zhè huí shì kě bù yí yàng.This time it's different.Everyday expression — 回 is idiomatic here.
Common mistakes
- Using 回 in formal writing (e.g., 我们第三回见面 instead of 第三次见面).
- Overusing 次 in casual spoken contexts where 回 sounds more natural (though not incorrect, it may sound stiff).
- Confusing 回 as a classifier with the verb 回 meaning 'to return' (e.g., 回一次 is 'return once', not 'one time').
- Using 回 in fixed phrases like 第一次 or 每次 — these always require 次.
FAQ
- When do I use 次 vs 回?
- Use 次 as the neutral, all-purpose classifier for occurrences; it works in any context. Use 回 for an informal, conversational tone, especially when telling stories or chatting with friends. In writing, default to 次.
- Are 次 and 回 always interchangeable?
- Not always. In set phrases like 第一次, 每次, 多次, only 次 is used. In informal speech, they are often interchangeable, but 回 sounds more casual and may feel out of place in formal writing.
- Can I use 回 in place of 次 in expressions like 第一次?
- No. 第一次 is a fixed expression; 第一回 is not standard for 'first time.' The same applies to 每次 and 多次.
- What is the nuance difference between 次 and 回?
- 次 is purely a classifier with no extra meaning. 回 originally means 'to return,' so when used as a classifier it can imply a separate 'occasion' or 'turn,' making it feel more vivid and colloquial.
