For all intents and purposes, in daily life in North America, the meaning is the same. If you say the words couch or sofa most people in English speaking countries will envision the same thing. And, lets face it, culture usually sets the standard for the meaning of words. When culture changes, the meanings of words tend to change. However, technically (or should I say linguistically) couch and sofa are different. The origin of the word sofa is Arabic and refers to a bench type of furniture raised slightly from the floor. This bench usually had a back and arms. The word couch is French in origin, from a word that meant to lie down. A couch was originally more like a bed, a raised seat without back or arms. But today they are basically the same thing. By the way, in England they don't really use the word couch. They prefer sofa or settee.
None No idea.
There really isn't much of a difference between the two, other than the name. Suggested answer: There is one difference between a couch and a chair, usually. Most often, if a chair looked like a couch of the same design, a chair would have one cushion (usually) and a couch would have more. Also, almost always, a couch is much longer than a chair, depending on the general appearance of each.
It's between the table and the couch/sofa.
