pyromania

The word 'pyromania' is a modern scientific compound, constructed in the 19th century from two ancient Greek roots to precisely label a newly identified psychological condition. The first element, 'pyro-', derives from the Greek word 'pyr', meaning fire, a term of Proto-Indo-European origin related to concepts of burning and heat. The second element, '-mania', originates from the Greek 'mania', signifying madness or frenzy. When combined, the term follows a classical model of medical terminology, literally translating to "fire madness." This construction logically describes the condition's core symptom—an irrational, compulsive obsession with fire-setting—by linking the ancient, concrete concept of fire with the abstract concept of pathological obsession.
