rug (Dutch)

Where does "rug" come from?

The Dutch word "rug" originates from the Proto-Germanic term *hrugjaz, which referred to the back or spine. Over centuries, it evolved through Old and Middle Dutch, appearing as "ruggi" and "rugge" respectively, before simplifying into its modern form. Today, it still primary denotes the backside or ridge, though in slang, it also functions as a shorthand for a thousand-guilder banknote.
