语域：neutral 常见场景：school、workplace staffroom 多用于英式英语，通常指学校等场所中供教职员工休息或备课的房间；美式英语中更常说 teachers' lounge。该词属于中性词，正式和日常场合都可使用。
staffroom 在英式英语读 /ˈstɑːfruːm/，美式读 /ˈstæfruːm/。room、broom、groom 都含 /ruːm/ 音，彼此押韵；它们与 staffroom 后半部分同音，但 staffroom 重音在第一个音节，所以不是完整押韵。classroom、bedroom、bathroom 也以 -room 结尾，拼写相似，但重音在前半部分，读音与 staffroom 并不相同，注意别按拼写类推。
