difference

n. unusual quality, distinction; disagreement; remainder (Mathematics)

Difference is the contrary of equality, in particular of objects. Differences can only be stated on the basis of a comparison or categorization. Since a complete comparison of objects or things is seldom possible in practice, only relevant or defining attributes are used for stating equality or difference. Similar objects are only different with respect to attributes of minor discriminative value.
