apart

Compared meaning: not connected to other things (adjective).

比较义项：分离的，不与其他事物相连（形容词）。

• apart 本词

  Apart is usually used after a verb (stand, live, grow apart) to stress the physical distance between two things or people, often with 'far' or a measurement.

  apart通常用在动词之后（如stand、live、grow apart），强调两者之间的物理距离，常与“far”或具体的距离搭配使用。

  The two houses stood far apart from each other.

  这两栋房子彼此相距很远。

• separate

  Separate emphasizes that two things are distinct or not combined, often used as an attributive adjective before a noun, with no idea of distance or loneliness.

  separate强调两者是不同的、未合并在一起的，常作定语放在名词前，不含“距离远”或“孤独”的含义。

  The kids have separate bedrooms so they don't argue at night.

  孩子们有各自独立的卧室，这样晚上就不会吵架。

• isolated

  Isolated highlights being cut off from other people or places, often implying loneliness, remoteness, or lack of contact, more than simple physical separation.

  isolated强调与他人或外界隔绝，常带有孤独、偏远或缺乏联系的意味，而不只是单纯的物理分隔。

  The small village felt isolated during the heavy snowstorm.

  在那场大暴风雪中，这个小村庄感觉自己被孤立了。

• detached

  Detached often describes choosing to stay uninvolved or emotionally distant from a situation, rather than simply being physically apart, though it can also describe a physically separate building.

  detached常用来描述在某件事情上主动保持不参与、情感上疏离，而不仅仅是物理上的分开，不过它也可以指物理上独立的建筑物。

  He remained detached during the argument, refusing to take sides.

  在那场争吵中，他始终保持超然的态度，拒绝选边站队。

Apart, separate, isolated, and detached all mean not connected, but focus differs. Apart usually follows a verb, stressing physical distance. Separate stresses being distinct, not combined. Isolated stresses being cut off from others, often with loneliness. Detached stresses choosing to stay uninvolved or emotionally distant.

这四个词都可以表示“彼此分开、不相连”，但侧重点不同：apart强调两者之间的物理距离，常放在动词之后；separate强调各自独立、不合并在一起，可作定语；isolated强调因缺乏联系而产生的孤立感，常带孤独或偏远的意味；detached强调主动保持不参与、情感上的疏离，也可指物理上独立的建筑物。这里不比较apart在“apart from”（除……之外）中的用法，也不比较separate作动词表示“（使）分开”的用法，以及isolated表示“个别的，孤立的（事件）”的用法。
