Some people might think Antoni Gaudi's name spawned the word Gaudy (or gawdy) because of his outlandish architecture. The word Gaudy means ostentatious or tastelessly ornamental.
Gaudi's architechture is the epitome of Gaudy. It is coincidence that his name is so close to the adjective as gaudy had been in use for a few hundred years before he was born. His Sagrada FamÃlia, is a large Roman Catholic church that began construction in 1882 and is scheduled for completion in 2026 (not a typo).
