1. The most exciting attractions are between two opposites that never met. 2. All colors are the friends of their neighbours and the lovers of their opposites. 3. Force and mind are opposites; morality ends were a gin begins. 4. Most people think that success and failure are opposites, but they both are products of the same process. 5. I'm smart, your not. I'm tall, your not. We're different in many ways, but somehow we're still friends.

Polar opposites are individuals or concepts that present contradictory or conflicting approaches to a theory or plan. A similar term is diametrical opposites, being at two extremes or contrary positions.
When two opposites are combined, their sum is zero. This is because one value cancels out the other; for example, when adding +5 and -5, the result is 0. This principle holds true for any pair of opposites, regardless of their magnitude.
Two integers are considered opposites if they are equal in absolute value but have different signs. For example, 5 and -5 are opposites because they are the same distance from zero on the number line, but one is positive and the other is negative. When added together, opposites always yield a sum of zero, illustrating their relationship.
If you mean the word itself, your question is an example. If you mean two opposite things, then "up and down are opposites"
