An Oxymoron is a combination of contradictory or incongruous words, such as 'Cruel Kindness' or 'Jumbo Shrimp' (Jumbo means 'large' while Shrimp means 'small').

It is a literary figure of speech in which opposite or contradictory words, terms, phrases or ideas are combined to create a rhetorical effect by paradoxical means.

The word 'Oxymoron' is originally derived from the Greek elements: oxy = sharp and moros (moron) = dull (foolish).
