Take extraterrestrial, it means out of or beyon earth (terra meaning earth) and it has the same prefix as extraordinary. Yay!
Me: no, it means out of the ordinary because the Latin prefix means out of or beyond, learn your shit.
people use extraordinary as something thats amazing or special in some way. but if there's ordinary and extraordinary. EXTRA-ORDINARY. if somethings extra ordinary then its just more ordinary than other things. how does that make is special in any way other than the fact that its more plain and boring than everything else.
I shall now use mathematics to prove my theory.
x must always equal to x
there is no such way that x=x+1
unless x happens to be infinity then infinity +1 would still equal to infinity because nobody bothers to count that high.
therefore extraordinary does not make sense unless it is used on a very ordinary but not ordinary subject
