Gobbledygook or gobbledegook is an English term used to describe nonsensical language, or sound that resembles language but has no meaning, or encrypted text.
The term is also used by plain language advocates to mean that something is being expressed in an overly complicated manner.
This word has been voted as one of the ten English words that were hardest to translate in June 2004 by a British translation company.
In J.K. Rowling's Harry Potter novels, Gobbledygook is the language spoken by goblins.
