When we want to request some one to do something we say:
Could you do ....? or Can you do ..... ?
So, please tell me when we say Could you ...? When we say Can you ...?
and the common reply for Can you ...? and Could you ....? are what?
Using "could" sounds more polite, but that doesn't mean that by using "can" you'll sound impolite. I'd observe how others speak. A lot depends on the context. Who are you talking to? What are you asking this person to do? There's also the tone of your voice.Originally Posted by Dinhtuong
