- Corneilus Osward Fudge: Cornelius is a common name and comes from the New Testament. Osward is likely a reference to Osward Monsley, the British prime minister who supported Adolf Hitler in WW2. He is also a lot like Neville Chamberlain, who tends to avoid war with Hitler. It shows Rowling’s distaste that the British politicians allow Hitler to get away with his crime like Fudge denied the rumors about Voldemort being back. “Fudge,” as a verb, means to “present or deal with (something) in a vague, noncommittal, or inadequate way, especially to conceal the truth or mislead,” which also sounds a lot like how Fudge ran the ministry.
- Fleur Isabelle Delacour: Fleur is “flower” from French. Isabelle comes from the French word “belle”, meaning beautiful. Delacour means “from the Court”.
- Cedric Diggory: Cedric is often misspelled as “Cerdic”, a sixth-century Saxon king. Diggory may come from “Sir Degare”, an English poem. It might also be a reference from C.S. Lewis’ character Digory Kirke.
- Amos Diggory: Amos is named after a Biblical prophet. In Hebrew, the name is related to the word “burden”, which he needed to carry after his son’s death.
