1540s, "structure of any kind," from Middle French machine "device, contrivance," from Latin machina "machine, engine, military machine; device, trick; instrument" (cf. Spanish maquina, Italian macchina), from Greek makhana, Doric variant of mekhane "device, means," related to mekhos "means, expedient, contrivance," from PIE *maghana- "that which enables," from root *magh- (1) "to be able, have power" (cf. Old Church Slavonic mogo "be able," Old English mæg "I can;" see may (v.)).

Main modern sense of "device made of moving parts for applying mechanical power" (1670s) probably grew out of mid-17c. senses of "apparatus, appliance" and "military siege-tower." In late 19c. slang the word was used for both "penis" and "vagina," one of the few so honored. Political sense is U.S. slang, first recorded 1876. Machine age is attested by 1851:
