🧐 再 zài vs. 又 yòu – What’s the Difference?

Both 再 (zài) and 又 (yòu) can mean “again” in Chinese, but they’re not the same. When should you use 再? When should you use 又? 

Let’s make it easy to understand!

🔍  Breakdown

• 再 (zài) – again (in the future)

• Use 再 when something will happen again later. 
• It’s about the future or something that hasn’t happened yet.

• 又 (yòu) – again (already happened)

• Use 又 when something has already happened again. 

• It’s about the past or something happening now.

💬  Easy Examples

✅ 再 (zài) – Again, but later

• 明天我再来。Míngtiān wǒ zài lái. 👉🏼 I’ll come again tomorrow.

• 请再说一遍。Qǐng zài shuō yí biàn. 👉🏼 Please say it again.

✅ 又 (yòu) – Again, and it already happened

• 他又迟到了。Tā yòu chídào le. 👉🏼He was late again.

• 你怎么又来了？Nǐ zěnme yòu lái le? 👉🏼 Why did you come again?

💡  What’s the Big Difference?

📌 再 is for later. You’re talking about something that will happen again in the future.

📌 又 is for now or before. Something already happened or is happening again.

⚠️  Common Mistakes (Watch Out!)

❌ 我明天又来。

Wǒ míngtiān yòu lái. (Wrong!)

✅ 我明天再来。

Wǒ míngtiān zài lái. (I’ll come again tomorrow.)

❌ 他再迟到了。

Tā zài chídào le. (Wrong!)

✅ 他又迟到了。

Tā yòu chídào le. (He was late again.)
