What does cleptomaniac mean?
A cleptomaniac is a person who has kleptomania, a recurrent and overpowering urge to steal. The term distinguishes this compulsion from ordinary theft motivated by financial need, greed, or opportunity. A person described this way may steal objects of little practical value, and the behavior is understood in a clinical context rather than simply as evidence of criminal intent. The word is formed from the Greek-based family of kleptomania and is used primarily in formal writing, reporting, literature, and historical discussion. It can sound dated or stigmatizing because it reduces a person's behavior to a label; modern accounts may instead discuss kleptomania as a condition or refer to an individual with kleptomania. The related adjective cleptomanic describes a tendency to steal in this compulsive way. Although the term has a relatively narrow meaning, it is memorable because it captures a motivation fundamentally different from ordinary acquisitive theft.

Etymology of cleptomaniac
The word belongs to a family built on the Greek klēptēs, meaning “thief,” and the suffix -mania, associated with madness or an intense and abnormal impulse. English kleptomania names the condition, while cleptomaniac was formed on this model to designate a person who has that compulsion. The spelling clepto- avoids an awkward vowel sequence, while the alternative spelling kleptomaniac is also encountered.
