shack (n.)[shack 词源字典]: 1878, American English and Canadian English, of unknown origin, perhaps from Mexican Spanish jacal, from Nahuatl (Aztecan) xacalli "wooden hut." Or perhaps a back-formation from dialectal English shackly "shaky, rickety" (1843), a derivative of shack, a dialectal variant of shake (v.). Another theory derives shack from ramshackle.
