machete (n.)youdaoicibaDictYouDict[machete 词源字典]
1590s (in pseudo-Spanish form macheto), from Spanish machete, 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).[machete etymology, machete origin, 英语词源]
