• Pinyin (with tone marks): dāndú
• Part of Speech: Adverb / Adjective
• HSK Level: HSK 4
• Concise Definition: To do something alone or to describe something as being separate from others.
• In a Nutshell: 单独 (dāndú) is all about separation and individuality. Think of it as putting a bubble around an action or an object. When you do something 单独, you do it without others. A 单独 room is a room that is separate, not shared. It emphasizes the state of being apart from the group, often for privacy, focus, or independence.

• 单 (dān): This character means “single,” “one,” or “individual.” Think of a single sheet of paper (传单 - chuándān, a flyer) or an odd number. It establishes the “one-ness” of the concept.
• 独 (dú): This character means “solitary” or “alone.” The left part, 犭, is the “animal” radical, and it can evoke the image of a lone wolf or a solitary creature. It carries the feeling of being the only one.
• Together, 单独 (dāndú) literally combines “single” and “solitary,” creating a powerful and clear term that means to be alone, by oneself, or separate from the pack.

In a traditionally collectivist culture like China's, the concept of doing things 单独 (dāndú) can have a different resonance than “alone” in the West. While Western cultures often prize individualism, Chinese culture has historically emphasized group harmony and collective activity. A useful comparison is the idea of eating a meal. In America, seeing someone eating alone at a restaurant is common and unremarkable. In China, while becoming more common, it might historically have been seen as a sign of loneliness or social isolation. An observer might wonder, “Why are they by themselves? Don't they have friends or family to eat with?” This is changing rapidly with modernization and the influence of the “One-Child Policy.” The generation of 独生子女 (dúshēngzǐnǚ - single children) grew up as the sole focus of their families, fostering a greater sense of independence and comfort with being 单独. The 独 (dú) in 独生子女 is the very same character as in 单独, highlighting a deep cultural connection. Today, 单独 (dāndú) is often used neutrally to mean “privately” or “independently,” but it's helpful to remember its slightly more “separate-from-the-group” cultural undertones.

单独 (dāndú) is a versatile word used in both formal and informal contexts. It's generally neutral, but its connotation can change based on the situation.

• As an Adverb (Describing an Action): This is its most common usage. It's placed before the verb to indicate an action is performed alone or privately.
  • “I need to talk to you alone.” - This implies privacy and seriousness.
  • “He completed the project by himself.” - This implies capability and independence.
• As an Adjective (Describing a Noun): When used with 的 (de), it describes something as being “separate” or “individual.”
  • “This is a separate room.” (e.g., a private hotel room)
  • “We need a separate invoice.” (e.g., in a business context)
• Formality: It's slightly more formal than the colloquial `一个人 (yī gè rén)`. You would use 单独 when asking for a private meeting with your boss, but you might use `一个人` to tell a friend you went to the movies by yourself.

• Example 1:
  • 老板想单独跟你谈谈。
  • Pinyin: Lǎobǎn xiǎng dāndú gēn nǐ tántan.
  • English: The boss wants to talk with you alone (privately).
  • Analysis: This is a classic example of 单独 implying privacy. It's not just “one person” talking to you; it's a conversation specifically set apart from others.
• Example 2:
  • 这个任务太难了，我一个人完不成，不能单独做。
  • Pinyin: Zhège rènwù tài nán le, wǒ yīgè rén wánbùchéng, bùnéng dāndú zuò.

  • 我们需要一个单独的房间开会。
  • Pinyin: Wǒmen xūyào yīgè dāndú de fángjiān kāihuì.
  • English: We need a separate room for the meeting.
  • Analysis: As an adjective with 的 (de), 单独 describes the room as being private and set apart from the main area.
• Example 4:
  • 旅行时，我更喜欢单独行动，这样更自由。
  • Pinyin: Lǚxíng shí, wǒ gèng xǐhuān dāndú xíngdòng, zhèyàng gèng zìyóu.
  • English: When traveling, I prefer to go about alone; it's more freeing this way.
  • Analysis: This example shows a positive connotation, where being 单独 is associated with freedom and independence.

  • Pinyin: Jiézhàng shí, qǐng gěi wǒmen dāndú de zhàngdān.

  • Analysis: A very practical use in daily life. It means you don't want a shared bill for the group.
• Example 6:
  • 她决定单独抚养这个孩子。
  • Pinyin: Tā juédìng dāndú fǔyǎng zhège háizi.
  • English: She decided to raise this child alone.
  • Analysis: This usage carries significant weight, implying she is doing it without a partner.

  • Pinyin: Nǐ yīnggāi xuéhuì dāndú jiějué wèntí.
  • English: You should learn to solve problems by yourself.
  • Analysis: This use of 单独 is about self-reliance and personal capability.
• Example 9:
  • 为了安全，晚上不要单独出门。
  • Pinyin: Wèile ānquán, wǎnshàng búyào dāndú chūmén.
  • English: For safety reasons, don't go out alone at night.
  • Analysis: Here, being 单独 has a negative connotation related to vulnerability.
• Example 10:
  • 每个参赛者都会被单独评估。
  • Pinyin: Měi gè cānsài zhě dōu huì bèi dāndú pínggū.
  • English: Each contestant will be evaluated individually.
  • Analysis: A formal usage showing that the evaluation is separate for each person, not as a group.

The most common point of confusion for learners is the difference between 单独 (dāndú) and 一个人 (yī gè rén).

• 单独 (dāndú): Focuses on the state of being separate, private, or apart from a group. It answers the question “How?” (e.g., How did you talk to him? 单独). It feels more deliberate and is slightly more formal.
• 一个人 (yī gè rén): Is a literal, factual description of quantity. It means “one person.” It answers the question “Who?” or “How many people?” (e.g., Who went? 我一个人 - Just me). It's more common in casual, everyday speech.

Common Mistake: Using 单独 where 一个人 is more natural.

• Incorrect: 我单独去看了电影。(Wǒ dāndú qù kànle diànyǐng.)
• Why it's awkward: While not grammatically wrong, it's overly formal for a casual activity. It sounds like you're making a point of having gone separately from a group.
• Correct and Natural: 我一个人去看了电影。(Wǒ yī gè rén qù kànle diànyǐng. - I went to the movies by myself.)

“False Friend” Note: 单独 is not the same as “lonely.” The Chinese word for “lonely” is 孤独 (gūdú), which carries a distinctly negative and sad emotion. You can be 单独 and feel happy, but you cannot be 孤独 and feel happy.

• 一个人 (yī gè rén) - The most direct comparison. A more colloquial and factual way to say “one person” or “by oneself.”
• 独自 (dúzì) - A close synonym to `单独`, often used in writing. It can carry a slightly more literary or emotional sense of “all by oneself.”
• 孤独 (gūdú) - Antonym in feeling. This means “lonely” or “lonesome” and is explicitly negative.
• 独立 (dúlì) - “Independent.” This is a character trait or a political status (e.g., an independent country). Being able to act `单独` is a sign of being `独立`.
• 单身 (dānshēn) - “Single” (in a romantic sense), unmarried. Shares the character `单`.
• 唯一 (wéiyī) - “The only one,” “sole.” This emphasizes uniqueness, while `单独` emphasizes separateness.
• 分开 (fēnkāi) - (Verb) “To separate.” You `分开` from the group in order to be `单独`.
