spearfish

The word "spearfish" is a transparent compound formed from two native English elements. The first element, "spear," originates from the Proto-Germanic speru-, referring to a pole weapon, which itself derives from the Proto-Indo-European root sper-, meaning "spear" or "pole." The second element, "fish," comes from the Proto-Germanic fiskaz, from the PIE root pisk-, meaning "fish." The compound logically names the creature by its most distinctive physical feature—its elongated, spear-like jaw or bill. This naming pattern is typical in English for describing animals based on a salient characteristic, such as "swordfish." The verb form, meaning to fish with a spear, follows the common pattern of zero-derivation from the noun.
