Etymology
The word 'pronghorn' is a transparent English compound, formed in the early 19th century to name the unique North American mammal. The first element, 'prong', refers to the distinctive forked shape of the animal's horns, each of which has a single forward-pointing tine or branch. The second element, 'horn', directly names the anatomical feature. The compound's logic is purely descriptive, literally meaning "forked-horn," which perfectly captures the creature's most defining physical characteristic, distinguishing it from other horned animals like deer or true antelopes.

Examples
The pronghorn is the fastest land mammal in North America.
We spotted a small herd of pronghorns grazing on the prairie.
Unlike deer, a pronghorn's horns are made of a keratin sheath over a bony core and are not shed.
