threshold

Compared meaning: an entrance or opening for a door (noun).

比较义项：门口，建筑物的入口（名词）。

• doorway

  Doorway literally names the empty space or frame in a wall where a door sits; it's concrete and physical, often used for someone standing, waiting, or filling that space.

  doorway 直接指墙上装门的那个空间或框架，具体而实在，常用来描述有人站在、等在或占满那个空间。

  His broad shoulders filled the doorway as he walked into the room.

  他宽阔的肩膀走进房间时几乎填满了整个门口。

• threshold 本词

  Threshold refers to the entrance as the point someone crosses into a space; it's more formal and often implies hesitation, ceremony, or the moment of entering.

  threshold 指的是入口作为一个人跨入某个空间的那个点，语气更正式，常带有迟疑、仪式感或“进入那一刻”的意味。

  She hesitated, then finally crossed the threshold into her new home.

  她犹豫了一下，然后终于跨过门槛，走进了她的新家。

Doorway and threshold both name a building's entrance. Doorway is concrete: the space or frame in a wall where a door sits. Threshold is formal, often implying hesitation or ceremony when entering. Threshold's underfoot-strip and 'beginning' senses are not compared here.

这两个词在“入口、门口”这个意义上很接近，容易混淆，但 threshold 更强调“跨进去的那个点”，常带有郑重、正式或稍带迟疑的意味；doorway 则单纯指墙上装门的那块空间，用法更直白具体。这里不比较 threshold 的“门槛”（脚下的那条横木）和“开端、起点”（如新时代的开端）这两个义项。
