na pewno – certainly
also
z pewnością,
oczywiście,
naturalniebyć może,
może would mean (maybe) be careful here because
może być means (it will do)
być może,
może,
możliwe,
prawdopodobnie also mean (perhaps)
Could someone also clear up usage of "może", "może być" and "możliwy"?
Most common use for these are:
może = (maybe or perhaps)
być może = (maybe or perhaps)
może być = (it will do)
możliwie = (possibly, conceivably) but also in a phrase like możliwie jak najwcześniej/najszybciej (at your earliest convenience)
ni ch**a - no way
much nicer way of saying this is
nie ma mowy,
nie da rady,
niemożliwe but your way works too and there is no way someone could mistaken it for something else. You could also say
nie ma mocnych meaning it's impossible.
