Language / -ski/-ska, -scy/ski, -wicz - Polish surnames help [185]

I think it's not good at all. Polska is noun. But it can makes some problems because we say sth like this: polska broń ( polish gun) polska granica ( polish border) polski prezydent ( polish president) Polska is definitely noun. It depends on the case, but dont be scared xd in hungarian there are 29 cases ;/
