How do you spell Hannukah?
1830, formed from mania + Greek kleptes "thief," from kleptein "to steal, act secretly," from PIE *klep- "to steal," an extention of root *kel- "to cover, conceal" (see cell; cf. Latin clepere "to steal, listen secretly to," Old Prussian au-klipts "hidden," Old Church Slavonic poklopu "cover, wrapping," Gothic hlifan "to steal," hliftus "thief"). Much-derided 19c. as a fancy term for old-fashioned thievery and an opportunity for the privileged to claim a psychological motive for criminal misbehavior.
There is a popular belief that some of the criminal laws under which the poor are rigorously punished are susceptible of remarkable elasticity when the peccadilloes of the rich are brought under judgment, and that there is some truth in the old adage which declares that "one man may steal a horse where another dare not look over the hedge." This unwholesome distrust is not likely to diminish if, in cases of criminal prosecutions where so-called respectable persons commit theft without sufficiently obvious motive for the act, they have their crime extenuated on the plea of kleptomania, as has recently occurred in several notable instances. ["Kleptomania," "The Lancet," Nov. 16, 1861]
kleptomania klep·to·ma·ni·a (klěp'tə-mā'nē-ə, -mān'yə)
An obsessive impulse to steal regardless of economic need, usually arising from an unconscious symbolic value associated with the stolen item.
A compulsion to steal, usually without either economic need or personal desire.
recurrent compulsion to steal without regard to the value or use of the objects stolen. Although widely known and sometimes used as an attempted legal defense by arrested thieves, genuine kleptomania is a fairly rare mental disorder. A kleptomaniac may hide, give away, or secretly return the stolen items, but he seldom uses them or attempts to profit by their resale. The kleptomaniac usually has the economic means to purchase what he steals and obtains gratification from the theft itself rather than from its object.
