A person who suffers from cleptomania; someone with an irresistible, compulsive urge to steal.
Greek kleptein (to steal) + mania (obsession) + -ac (person). The suffix -ac became common for naming people with specific conditions, following the pattern of 'maniac,' 'pyromaniac,' etc.
People with cleptomania often feel shame and guilty remorse immediately after stealing—their minds are essentially fighting their own hands, which is why it's considered a genuine mental health condition rather than just wickedness.
