The statement "Jonathan Swift wrote for the causes of England," is false.
The statement "The English language is based on Greek," is also false.
Jonathan Swift was an Anglo-Irish satirist, essayist, political pamphleteer, poet and cleric who served as Dean of St Patrick's Cathedral, Dublin.
English is a West Germanic language that was first spoken in early medieval England and eventually became a global lingua franca.
The language received its name from the Angles, one of the Germanic tribes that migrated to the area of Great Britain currently known as England.
