"rage, madness, angry mania," late 15c., furour, from Old French fureur (12c.), from Latin furor "a ravaging, rage, madness, passion," which is related to furia "rage, passion, fury" (see fury).
"morbid and uncontrollable sexual desire in women," 1775, in English translation of "Nymphomania, or a Dissertation Concerning the Furor Uterinus" (1771) by French doctor Jean Baptiste Louis de Thesacq de Bienville (1726-1813), coined from Greek nymphē "bride, young wife, young lady" (see nymph) + mania "madness" (see mania). Perhaps influenced by earlier French nymphomanie. Defined as "a female disease characterized by morbid and uncontrollable sexual desire." Compare also nympholepsy.
