Pleonasm

Uncommon card · No. 178405

Pleonasm (; from Ancient Greek πλεονασμός pleonasmós, from πλέον pléon 'to be in excess') is redundancy in linguistic expression, such as "black darkness", "burning fire", or "the man he said". It is a manifestation of tautology by traditional rhetorical criteria. Pleonasm may also be used for emphasis, or because the phrase has become established in a certain form. Tautology and pleonasm are not consistently differentiated in literature.
