• Summary: 世界 (shìjiè) is the most common Chinese word for “world.” Composed of the characters 世 (shì - generation, era) and 界 (jiè - boundary, realm), it encompasses everything from the physical planet Earth to abstract concepts like “the world of music” or a person's inner world. As a foundational HSK 2 term, understanding the versatile meaning of 世界 is essential for any beginner learning Mandarin to discuss global topics, personal experiences, and specific domains.

• Pinyin (with tone marks): shìjiè
• Part of Speech: Noun
• HSK Level: HSK 2
• Concise Definition: The world, the Earth; a field, sphere, or domain.
• In a Nutshell: 世界 is the go-to Chinese word for “world.” It's incredibly versatile and can be used in almost any context where you would use “world” in English. Think of it as the container for all of humanity, culture, and existence, as well as a way to describe a specific area of interest, like the “fashion world” or the “animal world.”

• 世 (shì): This character originally referred to a period of thirty years, or one generation. It has since expanded to mean an era, an age, or life itself. It represents the dimension of time.
• 界 (jiè): This character means a boundary, border, or realm. The top part 田 (tián) means “field,” and the bottom part gives a sense of division. It represents the dimension of space.

By combining 世 (time/era) and 界 (space/boundary), the word 世界 creates a complete and philosophical concept: the “world” is everything that exists within the boundaries of space and time.

• In Chinese thought, 世界 is a comprehensive term that captures the totality of human experience. It is a key component in modern concepts like 世界观 (shìjièguān), or “worldview,” which is a person's fundamental cognitive orientation encompassing their knowledge and point of view.
• It's interesting to compare 世界 (shìjiè) with a more traditional, historical Chinese concept: 天下 (tiānxià), which translates to “all under heaven.” While 天下 historically implied a Sino-centric world order with China at the center, 世界 is a more modern, neutral, and globalized term that views the world as a community of nations. The shift from using 天下 to 世界 in many contexts reflects China's changing role and perception of its place on the global stage.

• The Physical Planet: Used to refer to the Earth and everything on it.
  • e.g., 世界地图 (shìjiè dìtú) - world map
  • e.g., 世界人口 (shìjiè rénkǒu) - world population
• A Specific Field or Domain: Similar to English, it can define a particular area of activity or interest.
  • e.g., 动物世界 (dòngwù shìjiè) - the animal world
  • e.g., 音乐世界 (yīnyuè shìjiè) - the world of music
• A Personal or Abstract Realm: It can describe a personal, emotional, or psychological space.
  • e.g., 在我的世界里… (zài wǒ de shìjiè lǐ…) - In my world…
  • e.g., 二人世界 (èr rén shìjiè) - “a two-person world,” a common phrase referring to the private, intimate time a couple spends together.

The term is generally neutral and used in both formal and informal settings.

  • 他的世界观非常积极。
  • Pinyin: Tā de shìjièguān fēicháng jījí.

• 世界 (shìjiè) vs. 地球 (dìqiú): This is the most common point of confusion for learners.
  • 世界 (shìjiè): Refers to “the world” in a broad sense, including humanity, cultures, societies, and abstract domains. It's about experience and existence. (e.g., the world of politics, the end of the world).
  • 地球 (dìqiú): Refers specifically to the planet Earth as a physical, astronomical, or geographical object. It's the “globe.” (e.g., The Earth revolves around the Sun.)
• Common Mistake Example:
  • Incorrect: 宇航员从太空看到了美丽的世界。 (Yǔhángyuán cóng tàikōng kàn dào le měilì de shìjiè.)
  • Reasoning: While not entirely wrong, it's less precise. An astronaut sees the physical planet.
  • Correct: 宇航员从太空看到了美丽的地球。 (Yǔhángyuán cóng tàikōng kàn dào le měilì de dìqiú.)
  • Explanation: You would use 地球 when talking about the planet as a blue sphere seen from space. You would use 世界 to talk about the people on that planet.

• 地球 (dìqiú) - The planet Earth; the globe. More scientific and physical than 世界.
• 天下 (tiānxià) - “All under heaven.” A traditional, historical term for the world, often with a China-centric perspective.
• 人间 (rénjiān) - The human world, the mortal realm. Often used with a poetic or philosophical flavor, contrasting with heaven or the divine.
• 宇宙 (yǔzhòu) - The universe, the cosmos. A much larger scope than 世界.
• 全球 (quánqiú) - Global, worldwide. Often used in technical, economic, or political contexts, like 全球变暖 (quánqiú biànnuǎn) - global warming.
• 国际 (guójì) - International. Refers to relations between nations.
• 世界观 (shìjièguān) - Worldview, outlook, ideology.
• 世纪 (shìjì) - Century. Uses the same character 世 (shì), linking the concept of “world” with “time.”
• 界 (jiè) - As a standalone word, it means boundary, circle, or kingdom (e.g., 动物界 - animal kingdom).
