• hall

  The most general, neutral word for an entrance room or passage in any building, from a school to a private house; not necessarily large or formal.

  hall 是最普通、中性的词，指任何建筑物入口处的房间或通道，从学校到私人住宅都可以，不一定宽敞或正式。

  Take off your shoes and leave them in the hall by the front door.

  把鞋子脱掉，放在前门旁边的门厅里。

• foyer

  A more formal, elegant word for an entrance hall in a public building such as a theater or hotel, often a space where people gather before or after an event.

  foyer 是更正式、优雅的词，指剧院、酒店等公共场所的入口大厅，常是活动前后人们聚集的空间。

  幕间休息时，大家都走到门厅（foyer）去喝点东西。

Hall, lobby, and foyer all name an entrance room. Hall is the most general, used everywhere. Lobby suggests a large, formal reception area, as in hotels. Foyer, from French, sounds more elegant, often in theaters. Other meanings are not compared here.

这三个词都指建筑物入口处的厅堂，但语域和典型语境不同：hall 最普通中性，学校、住宅等各种建筑的门厅都可以用；lobby 强调宽敞正式，常见于酒店、写字楼、公寓楼的接待区；foyer 源自法语，语气更文雅，常指剧院、酒店等公共场所供人聚集、休息的门厅。这里不比较 hall 表示“大厅、礼堂”（如 town hall）的意思，也不比较 lobby 作动词表示“游说”的意思。
