Pronunciation

Forms

rospo m (plural rospi)[1] The oldest form is Old Italian rosco, and forms of the rosco type are well attested in the Venetian dialects;[2][3][4] ròsco is recorded as a dialect form.[2][3][4] The feminine is rospa.[5]

Etymology

Its origin is uncertain.[6][7][8][9] For Nocentini it is inherited from Late Latin ruscus, recorded only once, in the 5th-century Polemius Silvius, a writer born in Gaul.[3] Following Alessio, Nocentini takes this as a Cisalpine word from Proto-Celtic *prosko-, which lost its ⟨p-⟩ and matches Proto-Germanic *frosk- (in German Frosch (“frog”)), from a verb root meaning to jump.[3] Forms of the type Venetian rosco would continue it directly.[3] Medieval Latin bruscus (11th century), with another initial, gave Ladin aoròsc and Romanian broască.[3][10]

DELI starts instead from an onomatopoeic base ⟨rosp-⟩, or from Vulgar Latin *broscus crossed with Latin ruspor (“to search, scratch about”), following Devoto, who also cites Old Milanese brosco.[2][11] DELI leaves open how ⟨-sc-⟩ became ⟨-sp-⟩.[2] Nocentini also explains the ⟨-sp-⟩, which prevails in Italo-Romance, by attraction of ruspare.[3] Nigra derived the word from Old High German frosk (“frog”), according to Körting.[12] Wiktionary suggests Proto-West Germanic *ruspōn (“to croak”), comparing Old High German rospōn (“to croak, rustle”) and Middle Low German rospen (“to croak, belch”).[1]

Nocentini notes that popular belief credited the toad with magical powers and the power of foretelling, which may explain why its name was deformed in so many ways.[3]

Earliest recorded meaning

The first record is the form rosco in Giacomino da Verona, in the second half of the 13th century;[2] rospo appears in the second half of the 14th century in a Latin–Gubbio glossary.[2] The sense is the toad, the tailless amphibian with thick warty skin whose glands give off an irritant milky fluid.[2]

Semantic evolution

The toad was long held to be poisonous;[13][4] Tommaseo's dictionary already notes that it is harmless and useful to farmers because it eats insects, worms and molluscs.[13][4] From before 1571 (Cellini) the word is applied to a very ugly person, and it also came to mean a surly, unsociable one.[2][6][9]

Two idioms are common: ingoiare il rospo “to swallow the toad”, to put up with something unpleasant, and sputare il rospo “to spit out the toad”, to speak out at last about what one has kept hidden.[5][14] In some regions rospo or pesce rospo is the monkfish, also called coda di rospo.[9][8] Ido and Volapük borrowed the word.[1]
