inconsistency, variation, diversity, imbalance, inequality, divergence, contrast, contrariety. Difference, discrepancy, disparity, dissimilarity imply perceivable unlikeness, variation, or diversity. Difference refers to a lack of identity or a degree of unlikeness: a difference of opinion; a difference of six inches.
Discrepancy usually refers to an inconsistency between things that should agree, balance, or harmonize: a discrepancy between the statements of two witnesses.
Disparity implies inequality, often where a greater equality might reasonably be expected: a great disparity between the ages of husband and wife.
Dissimilarity indicates an essential lack of resemblance between things in some respect comparable: a dissimilarity between social customs in Asia and America. 6.
