• Summary: Discover the meaning of 定义 (dìngyì), the essential Chinese word for “definition” and the verb “to define.” This guide explores how this HSK 5 term is used in academic, legal, and philosophical contexts. Learn the crucial difference between 定义 (dìngyì) and the more common word for “meaning,” 意思 (yìsi), through practical examples and cultural insights, helping you communicate with greater precision in Mandarin Chinese.

• Pinyin (with tone marks): dìngyì
• Part of Speech: Noun, Verb
• HSK Level: HSK 5
• Concise Definition: (Noun) A formal statement of the exact meaning of a word or concept; (Verb) To state or describe the exact meaning of a word or concept.
• In a Nutshell: 定义 (dìngyì) is the direct equivalent of the English word “definition.” It's a formal and precise term used when you need to be exact. Think of dictionary entries, legal contracts, scientific papers, or serious philosophical discussions. It functions as both the *act* of defining something (a verb) and the *result* of that action—the definition itself (a noun).

• 定 (dìng): This character means “to fix,” “to settle,” or “to decide.” It often implies stability and certainty. Picture “fixing” something in place so it doesn't move.
• 义 (yì): This character can mean “righteousness” or “justice,” but in many contexts, it simply means “meaning” or “significance.”
• Together, 定 (dìng) and 义 (yì) literally combine to mean “to fix the meaning.” This perfectly captures the essence of creating a clear, stable, and unambiguous definition for a concept.

While “definition” might seem like a universal, culture-free concept, its importance in Chinese thought is noteworthy. The idea of precise definitions is central to the ancient Confucian concept of “正名” (zhèngmíng), or the “Rectification of Names.” Confucius believed that social harmony and order could only be achieved if words aligned perfectly with reality. A ruler must act like a ruler, a father like a father, and so on. This required a clear 定义 (dìngyì) for every role and concept in society. If words become unclear, actions become confused, and society falls into chaos. In contrast to the Western Socratic method, which often uses definitions as a starting point for a dialectical search for universal truth, the Confucian use of 定义 (dìngyì) is more pragmatic and socially oriented. It's about creating a stable framework for ethical behavior and social order. This underlying value can still be seen today in the emphasis on clarity and precision in formal, legal, and educational contexts in China.

定义 (dìngyì) is used when precision and formality are required. It's not typically a word for casual, everyday chatter.

• Academic and Educational Contexts: This is the most common environment for 定义. It's used constantly in textbooks, lectures, and research papers.
  • e.g., “请给这个科学术语下个定义。” (Please give a definition for this scientific term.)
• Legal and Business Contracts: Precision is paramount in law and business, making 定义 essential for specifying terms, obligations, and scope.
  • e.g., “合同的第一部分定义了所有关键术语。” (The first part of the contract defines all key terms.)
• Formal or Philosophical Discussions: When discussing abstract concepts like love, success, or freedom, using 定义 elevates the conversation from a casual chat to a more serious analysis.
  • e.g., “每个人对‘成功’的定义都不同。” (Everyone's definition of 'success' is different.)

• Example 1:
  • 词典里有这个词的准确定义。
  • Pinyin: Cídiǎn lǐ yǒu zhège cí de zhǔnquè dìngyì.
  • English: The dictionary has an accurate definition of this word.

• Example 2:
  • 你能帮我定义一下“人工智能”吗？
  • Pinyin: Nǐ néng bāng wǒ dìngyì yíxià “réngōng zhìnéng” ma?
  • English: Can you help me define “artificial intelligence”?
  • Analysis: Here, 定义 is used as a verb. The particle “一下 (yíxià)” softens the request, making it polite.
• Example 3:
  • 根据法律定义，这属于商业欺诈。
  • Pinyin: Gēnjù fǎlǜ dìngyì, zhè shǔyú shāngyè qīzhà.
  • English: According to the legal definition, this constitutes commercial fraud.
  • Analysis: This highlights the use of 定义 in a formal, legal context where precision is critical.

  • Pinyin: Lǎoshī yāoqiú wǒmen gěi měi ge guānjiàn gàiniàn xià dìngyì.
  • English: The teacher required us to provide a definition for every key concept.
  • Analysis: The phrase “给…下定义 (gěi…xià dìngyì)” is a common pattern meaning “to give a definition for…” or “to define…”.

  • 幸福很难被定义，因为它对每个人来说都不同。
  • Pinyin: Xìngfú hěn nán bèi dìngyì, yīnwèi tā duì měi ge rén láishuō dōu bùtóng.
  • English: Happiness is hard to be defined, because it's different for everyone.
  • Analysis: This sentence uses 定义 in a passive structure with “被 (bèi)” to talk about an abstract concept that resists a single, universal definition.
• Example 6:
  • 我们首先需要定义项目的范围。
  • Pinyin: Wǒmen shǒuxiān xūyào dìngyì xiàngmù de fànwéi.
  • English: We first need to define the scope of the project.

  • Pinyin: Zhè běn jiàokēshū duì quánqiúhuà de dìngyì fēicháng qīngxī.
  • English: This textbook's definition of globalization is very clear.
  • Analysis: Demonstrates how 定义 (noun) is often paired with adjectives like “清晰 (qīngxī)” (clear) or “模糊 (móhu)” (vague).

  • 你如何定义你自己的成功？
  • Pinyin: Nǐ rúhé dìngyì nǐ zìjǐ de chénggōng?
  • English: How do you define your own success?
  • Analysis: A common philosophical or interview question. Using 定义 here asks for a thoughtful, well-structured answer, not just a casual thought.
• Example 10:
  • 这个术语没有一个普遍接受的定义。
  • Pinyin: Zhège shùyǔ méiyǒu yí ge pǔbiàn jiēshòu de dìngyì.
  • English: This technical term does not have a universally accepted definition.
  • Analysis: A phrase often heard in academic discussions where concepts are contested or evolving.

The most common mistake for learners is confusing 定义 (dìngyì) with 意思 (yìsi). While both relate to meaning, they are not interchangeable.

• 定义 (dìngyì): A formal, precise, often technical “definition.” It's objective and aims for clarity. Think of a dictionary or a legal document.
• 意思 (yìsi): The general, everyday “meaning” of something. It can be a word's meaning, the meaning of a gesture, or someone's intention. It's much broader and more casual.

Rule of Thumb: If you could say “dictionary definition” in English, use 定义. If you would just say “meaning,” you probably want 意思. Incorrect Usage:

• Wrong: 你这句话的定义是什么？ (Nǐ zhè jù huà de dìngyì shì shénme?)
• Why it's wrong: This sentence sounds overly formal and strange, like asking for a dictionary entry for a casual sentence.
• Correct: 你这句话是什么意思？ (Nǐ zhè jù huà shì shénme yìsi?)
• English: What do you mean by that sentence?

Correct Usage:

• Correct: “熵”的科学定义是什么？ ( “Shāng” de kēxué dìngyì shì shénme?)
• English: What is the scientific definition of “entropy”?
• Why it's right: Here, you are asking for a formal, scientific definition, so 定义 is the perfect word.

• 意思 (yìsi) - The general, common word for “meaning.” Far more frequent in casual conversation than 定义.
• 解释 (jiěshì) - Explanation; to explain. An explanation often follows or expands upon a definition.
• 概念 (gàiniàn) - Concept; idea. This is often the thing that requires a 定义.
• 术语 (shùyǔ) - Terminology; technical term. Words that require a precise 定义, especially in specialized fields.
• 规定 (guīdìng) - Regulation; rule; to stipulate. A type of official definition that establishes a rule or standard.
• 界定 (jièdìng) - To define; to delimit. Very similar to 定义, but often carries a stronger sense of setting boundaries or limits.
• 阐述 (chǎnshù) - To elaborate; to expound upon. To give a more detailed account that goes far beyond a simple 定义.
• 正名 (zhèngmíng) - Rectification of names. A core Confucian philosophical concept that underscores the cultural importance of clear definitions for social roles.
