Hi, I'm a bit confused by this word... looked up in dictionary and saw the few examples there @ lingvo but still not sure exactly what it means. My friend seems to use it all the time.

I'll ask a question about something and he might respond

вроде да

or вроде something else (sorry my memory is not great so I can't remember the other examples)

so what it exactly does it mean in this context?

#1 guess: probably or likely

#2 guess: almost definitely or most likely

#3 guess: definitely

or does it mean something else?

I am thinking it means #1... but it seems this is an important word so any insight appreciated. thanks

If it does mean #1, could I use it interchangeably with the word наверно ?
