It was the title for the kangaroo rat within the fictional language of the desert Fremen, spoken all through the guide:
Muad’Dib is smart within the methods of the desert. Muad’Dib creates his personal water. Muad’Dib hides from the sun and travels within the cool night time.

Usually, they feed on seeds, roots, stems, leaves and, sometimes, bugs. They can survive with out consuming water for lengthy intervals of time. Most of their hydration comes from the meals they eat, which has a excessive water content material.
Not like the fictional Dune selection, kangaroo rats don’t gather dew on their ears. However their kidneys are not less than 4 occasions extra environment friendly at retaining water and excreting salt than these of people. Just like the desert Fremen clad of their stillsuits, they’re tailored to pay attention their urine. This minimizes water loss and maximizes conservation.

As Muad’Dib discovered from the Fremen, usually the very best protection is an efficient assault.
