The World.
"from Latin mundanus, from mundus, world."
It's widely (mistaken use...) used as the meaning of normal, earthly, to distinct regular person from a gifted/special one...
why is it a mistake... since
time has changed the meaning of this word ... misunderstanding the meaning of WORLD or
EARTH as Regular or Not Special .... making us a "Regular" and everything else is : Special in a
good way... or a better than the "mundane" one...
Mundane means the world... and the world is everything but "Regular" the world/
earth(and all the rest...) is incredible... we haven't even started to understand it ... let
alone tag it as something less than anything... etc.
