Root Explanation

**Shellduck** → The word 'shelduck' is derived from 'shel' (from Old English *sceald*, meaning to cover or shield) and 'duck' (from Old English *duce*, meaning to dive or duck). The term refers to a type of waterfowl that is often found in marshy areas, suggesting a bird that is covered or shielded by its habitat.

Memory Tip

Think of a bird that is 'covered' ('shel') in its natural habitat and 'diving' ('duck') into the water — that's why a shelduck is a type of waterfowl.
