Forms

peto m (plural peti)[1]

Etymology

It is inherited from Latin pēditum (“fart”), formed from the past participle of pēdō (“to break wind”).[2][3][4][1][5] The form is northern: the /d/ between vowels was lost and the diphthong that resulted was reduced to /e/, as in prete.[6] DEI and the GDLI also call it a word of northern origin, and DEI allows for a borrowing from Old French pet, recorded in the 13th century.[7][8] The southern dialects kept the consonant: Neapolitan pérete is the Neapolitan outcome.[3][9] In Italy the Latin verb was replaced by the iterative Vulgar Latin *pēditō.[7]

The Latin word continues in French pet, Occitan pet, Catalan pet, Portuguese peido and Sardinian pidu in Campidanese.[3][9]

De Vaan traces pēdō through Proto-Italic *pezd- to Proto-Indo-European *pesd- (“to fart”), whose descendants include Ancient Greek βδέω (bdéō, “to fart”) and Lithuanian bezdėti.[10] The same verb gave pōdex (“anus”), the source of podice.[10][2] Nocentini sets the root beside Proto-Indo-European *perd-, the source of πέρδομαι (pérdomai), and calls both imitative.[3]

Earliest recorded meaning

The first record is in a poem of Cecco Angiolieri of Siena, from the end of the 13th century, in the same sense as today.[11] DELI's first example is Franco Sacchetti's, before 1400: a man lets off a fart so loud that it seemed a bombard (tirò un peto sì grande che parve una bombarda).[2][8]

Semantic evolution

Old Italian could use a feminine plural le peta, found in the Tuscan Aesop.[12][13] The usual phrases were trarre un peto (Firenzuola) and tirare un peto.[13] The Malmantile has riavere il peto, to get one's strength back, now obsolete.[12]

Derivatives include the verb spetezzare, from the 14th century, taken from Venetian spetezar.[3][9] The Tuscan péra, a tall story, used as a euphemism for a fart, adapts Neapolitan pérete.[3] In Tuscany peto di lupo is a name of the puffball.[14][15]
