Hello,

Would it be possible to give me some direction in how to use the vietnamese modal verbs: "can", "nen", "phai", "co the"? for need to, have to, should, must, will? Like ex. I shall/ must ( ex.my mother is ill) make breakfast, so I might have to make Chau.What do I need to buy, and where should I go.
Is it right, that giving somebody an advice, you use "nen"? Can you also use nen, when you explain to other, what you intend to do?
I know, this is not very clearly asked of me, but you might understand.
Cam on rat nhieu!
