"hub of a cart-wheel," Middle English, from Old English nafa, nafu, from Proto-Germanic *nabo- (source also of Old Saxon naba, Old Norse nöf, Middle Dutch nave, Dutch naaf, Old High German naba, German Nabe), perhaps connected with the root of navel on notion of centrality (compare Latin umbilicus "navel," also "the end of a roller of a scroll;" Greek omphalos "navel," also "the boss of a shield").

pike-like fish, 1765, American English, shortening of garfish (mid-15c.), from fish (n.) + Middle English gare, gore "a spear," from Old English gar "spear," from Proto-Germanic *gaisa- "spear" (source also of Old Norse geirr "spear; point of an anvil," Old Saxon, Old High German ger, German Ger "spear"), from PIE *ghaiso- "a stick, spear" (see goad (n.)). The fish so called for its long sharp snout. Compare Edgar, garlic.
