Forms

pazzo (feminine pazza, masculine plural pazzi, feminine plural pazze); also a noun, pazzo m, pazza f[1][2] Old Italian also has paccio, paço and pascio.[3]

Etymology

The origin is disputed, and DELI, GRADIT and Sabatini–Coletti call it uncertain.[4][2][5] Nocentini and Devoto–Oli take it as the short past participle of the verb from Vulgar Latin *pactiāre (“to press, beat”), from Latin pactus (“pressed together”): the madman would be one who has had a knock on the head, as in picchiato and tocco.[6][7] In support Nocentini points to strapazzare “to batter”, from a *extrapactiāre, and to the southern variant paccio, since ⟨-ctj-⟩ gave both ⟨zz⟩ and ⟨cc⟩ in Italo-Romance, as in the pair of verbs with the variant strapacciare.[6] Biadene had already proposed the Vulgar Latin verb, but through a dialect Venetian pazzo (“dirty”) of Treviso and the Val di Fiemme;[6][8] Prati rejected that on grounds of meaning.[6][8]

The older explanation, Salvioni's, is Latin patiēns (“suffering; sick”), and it is accepted by Meyer-Lübke, Körting and Devoto.[9][10][11] DEI thinks the word a half-learned medical term from that participle, which through a medieval spelling Medieval Latin paciens would also explain the southern form and older pàcio “foolish”.[12] Nigra objected that in popular thought a madman is odd and unreasonable rather than ill, and proposed a clipping of pupazzo “puppet”, which Prati and Meyer-Lübke do not accept.[8][9]

Earliest recorded meaning

DELI's first record is the Bolognese Serventese dei Lambertazzi e dei Geremei of about 1280, with the sense “mad”.[4][2] The TLIO's earliest text is the Venetian Proverbia que dicuntur, and its first sense is “without reason because of a mental disorder”.[3]

Semantic evolution

Already at the end of the 13th century, in Simone Pallavillani, the word was used for someone who behaves senselessly, and Boccaccio used it for “foolish”.[4][13] Old Italian also had pazzo d'amore, mad with love, and used the feminine noun for a madwoman.[3] Pazzia “folly” is in Giordano da Pisa before 1311, pazzesco in the 14th century and pazzerello in San Bernardino before 1444.[4][6] The phrase cose da pazzi is probably Neapolitan in origin.[4]

Today the adjective also intensifies (innamorato pazzo), describes reckless spending or speed, and changeable weather.[2][7][14] DEI suggests that English patch “fool” (1549) may be an anglicised pazzo, and German had Pazzo in 1876.[12][15]
