| 词根词缀 | 词源： O.E. gemædde (pl.) "out of one's mind" (usually implying also violent excitement), also "foolish," earlier gemæded "rendered insane," pp. of a lost verb *gemædan "to make insane or foolish" (related to gemad "mad"), from P.Gmc. *ga-maid-jan, demonstrative form of *ga-maid-az "changed (for the worse), abnormal" (cf. O.S. gimed "foolish," O.H.G. gimeit "foolish, vain, boastful," Goth. gamaiþs "crippled, wounded," O.N. meiða "to hurt, maim"), from intensive prefix *ga- + PIE *moito-, pp. of base *mei- "to change" (cf. L. mutare "to change," mutuus "done in exchange," migrare "to change one's place of residence;" see mutable). Emerged in M.E. to replace the more usual O.E. word, wod (see wood (adj.)). Sense of "beside oneself with excitement or enthusiasm" is from early 14c. Meaning "beside oneself with anger" is attested from c.1300, but deplored by Rev. John Witherspoon (1781) as an Americanism, and now competes in Amer.Eng. with angry for this sense. Of dogs, "affected with rabies," from 1800.
