void

Compared meaning: containing nothing (adjective).

比较义项：空的，不含任何东西（形容词）。

• empty

  The most general and common word for containing nothing; used for any space, container, or place, with no special formality or specific context.

  语气最普通、最常用的“空的”，可以用来形容任何空间、容器或场所，没有特殊的正式程度或使用场合限制。

  He found the fridge completely empty and had to order takeout.

  他发现冰箱里空空如也，只好叫外卖。

• vacant

  Specifically describes a place, seat, position, or building that is unoccupied though meant to be used; not used for containers like boxes or fridges.

  专指本该有人使用却无人占用的场所，例如座位、职位或建筑物；不用来形容箱子、冰箱等容器。

  The manager position has been vacant since she resigned last spring.

  经理这个职位自从她上个春天辞职后就一直空缺。

• void 本词

  A formal, often literary word for something totally and utterly empty, emphasizing completeness; frequently appears in the phrase 'void of' or in legal use for something invalid.

  语气正式、偏文学化，强调“彻底空无”，常出现在“void of”（完全没有……）这一搭配中，也用于法律语境表示“无效”。

  The desert stretched for miles, utterly void of any trees or shade.

  那片沙漠绵延数英里，完全没有一棵树，也没有一丝树荫。

• blank

  Describes surfaces meant to carry writing, images, or information—paper, forms, screens—that have nothing on them; not used for physical spaces or rooms.

  专门形容纸张、表格、屏幕等本应写有文字、图像或信息却空无一物的表面；不用来形容房间等实际空间。

  She stared at the blank page, unable to think of how to begin.

  她盯着空白的一页，不知道该如何下笔。

All four can mean 'empty'. Empty is the most general, for any space. Vacant means a seat or job is unoccupied. Void is formal, stressing complete emptiness. Blank describes surfaces for writing, like paper. Not covered: vacant/blank as 'showing no expression', void as 'legally invalid'.

这四个词都能表示“空的”，但语气和适用场合不同：empty最通用，可以形容任何空间或容器；vacant专用于座位、职位、房屋等本该有人使用却无人占用的场合；void语气正式，强调“彻底空无”，常见于“void of”这类搭配，也可指法律上“无效”；blank专指纸张、表格、屏幕等本应写有内容却空白的表面。这里不比较vacant和blank表示“茫然的”（vacant stare、a blank look）的引申义，也不比较void表示“无效”（null and void）的法律义。

Compared meaning: an empty space with nothing in it (noun).

比较义项：真空／空无一物的空间（名词）。

• vacuum

  Vacuum is the precise scientific term for a space with no air or matter at all, used for physical phenomena like outer space or sealed containers; it is neutral, technical language, never emotional.

  vacuum 是科学意义上的精确说法，指完全没有空气或物质的空间，用于描述外太空或密封容器等物理现象；语气中性、专业，从不用来形容情感。

  The container was sealed tightly to create a vacuum with no air inside.

  这个容器被密封起来，制造出一个没有空气的真空。

• void 本词

  Void is a more literary word for a vast, empty space, often used figuratively for silence, darkness, or emotional emptiness rather than the strict scientific absence of matter.

  void 是较为文学化的词，形容广阔而空荡的空间，常用来比喻寂静、黑暗或内心的空虚，而不是强调科学意义上物质的缺失。

  Losing her felt like staring into an endless, empty void.

  失去她的感觉，就像凝视着一片无边无际的空虚。

Vacuum and void both mean an empty space with nothing in it. Vacuum is the neutral scientific term for emptiness, like outer space. Void is more literary, often figurative for a vast emptiness. It does not compare vacuum as a verb, or void as 'invalid'.

这两个词都可以指“空无一物的空间”，但语域和用法不同：vacuum 是科学、中性的说法，强调完全没有空气或物质；void 更文学化，常用来比喻浩瀚、令人不安的空虚，或内心的空虚感。这里不比较 vacuum 作动词“用吸尘器打扫”的用法，也不比较 void 作形容词“（合同等）无效的”的用法。
