mania: [14] Greek maníā meant ‘madness’. It goes back ultimately to Indo-European *mn-, *men- ‘think’, the same source as produced English mind. It reached English via late Latin mania. Of its derivatives, maniac [17] comes from late Greek maniakós, but manic [20] is an English formation. Closely related to maníā was the Greek verb maínesthai ‘be mad’; from it was derived mainás, the name for a fanatical female follower of Dionysus, which English has adopted via Latin as maenad [16]. => maenad, manic, mind
mania (n.)
late 14c., "mental derangement characterized by excitement and delusion," from Late Latin mania "insanity, madness," from Greek mania "madness, frenzy; enthusiasm, inspired frenzy; mad passion, fury," related to mainesthai "to rage, go mad," mantis "seer," menos "passion, spirit," all from PIE *men- (1) "to think, to have one's mind aroused, rage, be furious" (see mind (n.)). Sense of "fad, craze" is 1680s, from French manie in this sense. Sometimes nativized in Middle English as manye. Used since 1500s (in imitation of Greek) as the second element in compounds expressing particular types of madness (such as nymphomania, 1775; kleptomania, 1830; megalomania, 1890).
