"Refurbished" looks and sounds as though, like "disturbed", it is made of an obvious prefix and a root nobody ever heard of, possibly that isn't even real. (Ever seen a brand new shiny car referred to as "furbished"?) Actually furbished is a legitimate word, though it isn't nearly as commonly used as its repetition.

"Disturb" at least has turbine and turbulent using the same root. Is there anything else that uses "furbish"?
