The word 'warthog' is a transparent English compound formed in the 18th century from two native Germanic roots. The first element, 'wart', directly references the prominent, wart-like facial protuberances that are the animal's most distinctive feature. The second element, 'hog', a common term for a swine, classifies it within the pig family. This name is a purely descriptive, zoological label created by European naturalists to categorize the African animal based on its striking physical appearance, rather than having a deep classical etymology.

Structure: wart + hog - wart: From Old English wearte, meaning a small, hard growth on the skin. In this compound, it describes the characteristic fleshy protrusions on the animal's face. - hog: From Old English hogg, meaning a domesticated pig, especially one reared for slaughter. It denotes the animal's type.
