Chair means single sofa?

chair means sofa in American language, it is a single sofa, a classic that our American foreign teacher said: Your chair is not chair, it isn't soft, it only is a 't complain , sit tamely!Our TA translator: Your seat is not a sofa, it's not soft, it's just a chair.

Don't complain, sit down.

So chair means sofa, but single sofa is generally written as armchair (armchair).

Note: Generally sit in a chair, not sit on, because foreigners think that they are sitting in the sofa, not sitting on the sofa.

The multi-person sofa is a couch or sofa

I don't think a chair is a chair, a sofa is a sofa, a sofa is a couch, but some chairs belong to a couch, but I don't think a sofa belongs to a chair

Yes, when I was in a foreign teacher's class, an American taught her, and she said that the chair is a chair and a single sofa, and the sofa is a long sofa.

Chair means sofa in the American language, and it is a single sofa.

Since such an authoritative book says so, it is correct.

I don't think, the chair is the chair, the sofa is the sofa, the sofa is the couch, but some of the chairs belong to the couch, but I don't think the sofa belongs to the chair
