Derived from Latin in- (negation) + con- (intensifying prefix) + sistere (to stand). The root sistere evolved into consistency, meaning "steadfastness" or "logical harmony." Adding in- flips the meaning to "lack of harmony" or "contradiction." The word reflects a logical opposition: standing together (consistency) vs. not standing together (inconsistency).
