英语词汇immunity的起源、历史背景-英语词源词典

词汇	immunity
词源	immunity n. late 14c., "exemption from service or obligation," from Old French immunité "privilege; immunity from attack, inviolability" (14c.) and directly from Latin immunitatem (nominative immunitas) "exemption from performing public service or charge, privilege," from immunis "exempt, free, not paying a share" (see immune (adj.)). Medical sense of "protection from disease" is from 1879, from French or German. Entries linking to immunity immune adj. mid-15c., "free, exempt" (from taxes, tithes, sin, etc.), from Latin immunis "exempt from public service, untaxed; unburdened, not tributary," literally "not paying a share," from assimilated form of in- "not, opposite of" (see in- (1)) + munis "performing services" (compare municipal), from PIE moi-n-es-, suffixed form of root mei- (1) "to change, go, move." Specific modern medical sense of "exempt (from a disease)," typically because of inoculation, is from 1881, a back-formation from immunity. Immune system attested by 1917. updated on October 06, 2016
