"very large diurnal raptorial bird of the genus Aquila," mid-14c., from Old French egle, from Old Provençal aigla, from Latin aquila "black eagle," fem. of aquilus "eagle," often explained as "the dark colored" (bird); see aquiline. The native term was erne.
Golf score sense is by 1908 (according to old golf sources, because it "soars higher" than a birdie).

"heavy knife or cutlass," used as a weapon and tool by the Spanish in the Americas, 1590s (in pseudo-Spanish form macheto), from Spanish machete "a chopping knife," probably a diminutive of macho "sledge hammer," alteration of mazo "club," which is probably [Barnhart] a dialectal variant of maza "mallet," from Vulgar Latin *mattea "war club" (see mace (n.1)). An alternative explanation traces macho to Latin marculus "a small hammer," diminutive of marcus "hammer," from a base parallel to that of Latin malleus (see mallet).
