1. facing. 2. incompatible, irreconcilable, unlike, differing. Opposite, contrary, reverse imply that two things differ from each other in such a way as to indicate a definite kind of relationship. Opposite suggests symmetrical antithesis in position, action, or character: opposite ends of a pole, sides of a road, views. Contrary sometimes adds to opposite the idea of conflict or antagonism: contrary statements, beliefs. Reverse suggests something that faces or moves in the opposite direction: the reverse side of a coin; a reverse gear.
