Four differences between parody and satire?
The words parody and satire are often used interchangeably but they are not synonymous.
1. Parody is typically aimed at a specific target
2. Parody uses caricatureA parody exaggerates commonly recognisable traits or features. It creates a visual or verbal caricature that its audience should immediately recognise.
An impressionist might do this by taking a real or imagined catch-phrase - the pound in your pocket was associated with British Prime Minister Harold Wilson, for example. A good parody requires accurate imitation of detail.
3. Satire is more broadly ideological.
Satire assumes some intention or purpose - to make a political point or expose a perceived failing. Jonathan Swift's Gulliver's Travels was aimed at various (long-forgotten) political targets but has endured because its broader themes are universal.
