Origin
Derived from French 'déranger', which originally meant 'to disturb or disrupt order'. Over time, the meaning evolved from physical disorder to mental disorder, eventually referring to a state of mental derangement or insanity.
Breakdown
de- (away, off) + ranger (to arrange, to put in order). The prefix 'de-' negates or reverses the action of 'ranger', literally meaning 'to put out of arrangement' or 'to disturb order'.
