Forms

furioso (feminine furiosa, masculine plural furiosos, feminine plural furiosas, metaphonic)[1] 15th-century texts write furiosso and foriozo; letters of 1619 and 1674 have furiozo.[2][3]

Etymology

It is borrowed from Latin furiōsus (“mad, raving, furious”).[2][1][4] The Latin adjective is formed from furia (“rage, madness”) with the suffix -ōsus, and the noun in turn from furō (“to rage”).[5][1]

The same Latin word gave Spanish furioso, Galician furioso, Catalan furiós, Italian furioso and French furieux.[6][7][1]

Earliest recorded meaning

Houaiss dates the word to the 15th century from Cunha's medieval slips, in the spellings furiosso and foriozo.[2] Its first sense was “possessed by fury”, raging.[2]

Semantic evolution

Latin furiosus was also a legal term for a madman, and Bluteau (1712–1728) still glosses doudo furioso “raving madman” with Latin words for frenzy.[5][8] Morais (1813) has the soul “stirred by great passion”, the raving madman who strikes out, and winds, waves and storms of great force.[9] The original Caldas Aulete adds “enthusiastic, passionate about something” (furioso pela boa música) and “great, extraordinary”.[10] In Rio Grande do Sul it is also said of a mad dog and of an excessively strong wind.[11]
