KK: /ˈneɪ.vəs/
A raised or discolored spot on the skin that can be present at birth or develop later. These spots are usually harmless and are often referred to as moles.
The dermatologist examined the naevus to ensure it was not harmful.
Naevus comes from Latin 'naevus' (meaning birthmark or mole). The word refers to a benign skin lesion that is often present at birth or develops shortly after.
Think of a 'birthmark' when you hear 'naevus', as it directly refers to a skin mark that is often present from birth.
