Pronunciation

Forms

rabbioso (feminine rabbiosa, masculine plural rabbiosi, feminine plural rabbiose)[1] Old forms include Old Italian rabioso, Old Italian rabioxo and Old Italian raioso.[2]

Etymology

It is inherited from Latin rabiōsus (“raving, rabid”), from rabiēs (“rage; rabies”) with the suffix -ōsus.[3][4][1][5] The same word is Old Occitan rabios, Spanish rabioso and Portuguese raivoso.[4] Sources differ on how it entered Italian: the GDLI calls it learned, Devoto–Oli derive it from the Italian noun, and Devoto explains it as the Latin word influenced by rabbia, whose double ⟨bb⟩ it shares.[2][6][7]

The Latin noun is related to rabiō (“to rave”), which Nocentini compares with Sanskrit words meaning “violence, impetus” and “impetuous”.[8]

Earliest recorded meaning

DELI's first record is the early 13th-century Canzone del fi' Aldobrandino, in the sense “having rabies”: Fugge ogni uomo da me più pauroso / che non dal can rabbioso (“Every man flees from me more fearfully than from a rabid dog”).[9][10]

Semantic evolution

Dante, in 1300–1313, already used the word in the extended senses “furious” and “immoderate, violent”, and Petrarch in 1374 for a person filled with rage.[9] Dante describes Gianni Schicchi going about rabbioso, mauling others like a rabid beast.[11]

The modern senses keep both lines: the medical one, of an animal or person with rabies, and the figurative ones, angry, quick-tempered, fierce, and of hunger, love or wind, violent and excessive.[3][6][12] In sport it is used for a short, intense effort, such as a cyclist's sprint.[3][6]
