Question

How do you define "right"??

Answer 1

Right .. here we go ..

First, I ll answer you with a question .. it is that which "right" do you really mean?
Or is it that they are all the same one and are actually equal?!

Well, right as a word, means the opposite of the left direction .. 
There is always the right choice and then come the choices that are left and from here it started to be right and left directions ..
As in the discussion about correct and wrong .. right is what is correct ..

Answer 2

The opposite of wrong and left! dah!
