客厅的英文是 "living room"。其中，"living" 这个词来源于拉丁语 "vita"，意思是"生活"，而 "room" 来源于古英语 "rum"，意思是"房间"。因此，"living room" 的意思就是"用来生活的房间"。
以下是一些英文例句：
The living room is the heart of the home.
We always have family meals in the living room.
I like to relax in the living room after a long day at work.
The living room is where we entertain our guests.
Can you please clean the living room before the party?
