why was 'sunset' disallowed when 'zachód słońca' means sunset
Of course Polish word for West is deeply connected to the sunset, but just the word zachód, does not mean exactly "sunset". just "set".
In Ukranian, it's захід zakhid, so I could have gotten this one right even without knowing it.
Does this mean the cardinal direction west or does it the west as in the western world?
It can mean both, same as in English.
