First of all, I thank u for answering my first question.
And second comes:
We use "must" for possibilities -strong ones.
Lets say, I saw my friend buy a bus ticket and I want to express a future possibility for him. What if I say:
- He must go on holiday nowadays.
I am not sure if there is such usage for must, can it be mixed with "neccessity function" of must.
He must be going on holiday.
(Nowadays doesn't work here as it refers to a general period of now, not the future- you could use 'soon', etc.)
