In addition to these kinds of "natural" binarity, antonym pairs arise in cases in which a larger contrast set exists: For instance black/white belong to the larger set of achromatic colors black/grey/white, and happy/Sad also contrast with angry, *aid, And surprised. Nevertheless, we oppose black/white and happy/sad as if there were DO other possibilities.It seems that when people. want to contrast things, they like to have just one other item to contrast it with. This raises the question of why we consider black the opposite of white instead of grey, and why sad is the opposite of happy rather than angry. You Might answer that black is the opposite of white because it is more different from white than grey is, but that answer does not work so well for the happy/sad/angry problem. since sad and angry are both' very different from happy.
