It's there a difference between bor and lever?
Leva refers to being alive.
Bo refers to residing somewhere.
Would you be directing this to one person or multiple since it uses "ni"?
One person if you are very polite and a little old fashioned. Otherwise more than one person
Why is "Var ligger du?" incorrect? From an English point of view are you not asking where they are located or is "bor" more general or larger area? Cheers
This sounds like you are asking someone (or his ghost) which graveyard he is lying in.
