Both 单独 (dāndú) and 独自 (dúzì) can mean “alone” or “by oneself.”
But there’s a small difference that can make your Chinese sound more natural.
Let’s look at how people actually use them!
🔹 1. 单独 (dāndú) — Alone / Separately / Privately
单独 often emphasizes doing something separately from other people or things.
It can mean alone, separately, or privately, depending on the situation.
✅ Examples
① 老师想单独跟你聊聊。
The teacher wants to talk to you privately.
② 这份文件不用发到群里,单独发给我就好。
You don’t need to send this file to the group. Just send it to me privately.
③ 我想要一个单独的房间。
I’d like a room of my own.
💡 Remember:
单独 doesn’t always mean being completely alone.
For example, when a teacher talks to you 单独, there are still two people in the conversation. The point is that other people aren’t included.

🔹 2. 独自 (dúzì) — Alone / By Oneself
独自 emphasizes doing or experiencing something without anyone accompanying you.
It can also describe completing something without other people’s help.
✅ Examples
① 她第一次独自坐飞机。
This is her first time flying alone.
② 他独自完成了这项工作。
He completed the task on his own.
③ 搬到上海以后,她开始独自生活。
After moving to Shanghai, she started living on her own.
💡 Remember:
独自 focuses on doing something without company or help.
It doesn’t necessarily mean feeling lonely!

🔍 3. What’s the Difference?
Here’s a simple way to remember them:
单独 → Separately / Privately
Focus: Doing something apart from others.
独自 → Alone / By Oneself
Focus: Doing something without company or help.
Can They Be Used Interchangeably?
Sometimes, yes!
Compare:
他单独去了北京。
He went to Beijing separately / on his own.
他独自去了北京。
He went to Beijing alone.
Both are correct.
However, 单独 can suggest that he went separately from other people, while 独自 more clearly emphasizes that nobody accompanied him.
The difference isn’t always strict. Context matters!

✏️ 4. One Useful Grammar Difference
Both words can appear before verbs.
单独 + Verb
-
单独讨论 — discuss separately
-
单独处理 — handle separately
独自 + Verb
-
独自旅行 — travel alone
-
独自生活 — live alone
But there’s another useful pattern:
单独的 + Noun
✅ 单独的房间 — a separate room
❌ 独自的房间
Why?
单独 can describe something as separate or individual.
独自 mainly describes how someone does something, so it isn’t normally used directly before a noun with 的.
💬 5. What About 一个人 (yí ge rén)?
Here’s something useful for everyday conversations!
Chinese speakers often use 一个人 to mean “alone.”
Compare:
我喜欢独自旅行。
I enjoy traveling alone.
我喜欢一个人旅行。
I like traveling by myself.
Both are perfectly natural.
独自 is used in both spoken and written Chinese, but 一个人 often sounds more casual in everyday conversation.

📝 6. Quick Practice!
Choose the word that best fits each sentence.
① 别把这两份文件放在一起,请 ______ 保存。
Don’t keep these two files together. Please save them separately.
A. 单独
B. 独自
② 没人陪她,她决定 ______ 去旅行。
Nobody could go with her, so she decided to travel alone.
A. 单独
B. 独自
✅ Answers
① A. 单独 (dāndú)
The files need to be saved separately.
② B. 独自 (dúzì)
She’s traveling without anyone accompanying her.
单独 is also possible in the second sentence, but 独自 emphasizes traveling without company more clearly.
🎯 Final Takeaway
Next time you want to say “alone” in Chinese, remember:
🔹 单独 (dāndú) — alone, separately, or privately.
🔹 独自 (dúzì) — alone or by oneself, without company or help.
🔹 一个人 (yí ge rén) — a common, natural way to say “alone” in conversation.
The words sometimes overlap, but their emphasis can be different.
Now it’s your turn! 😊
