Forms

deretano m (plural deretani)[1] Old forms include Old Italian diretano, Old Italian deredano, Old Italian derean and Old Italian dirridanu.[2] DEI notes that the adjective once spread over all of northern Italy, as Old Italian dredan and Old Italian driano.[3]

Etymology

It is inherited from Vulgar Latin *deretrānus, an adjective formed on Late Latin dē retrō (“behind”), which lost its second /r/ by dissimilation from the first.[4][5][6][7][8] GRADIT and Zingarelli describe it as the Late Latin phrase with the suffix -ano, and the TLIO derives it within Italian from Old Italian dereto (“behind”).[9][10][2] The noun “backside” is the old adjective “rear, last” used as a noun, a jocular euphemism.[8][4]

The same adjective is Old French derrain and Old Occitan dereiran, both meaning “last”; modern French dernier comes from a further derivative *deretranarius.[4][11][12] The Latin phrase is de (“from”) and retro (“backwards, behind”), first found in the Vetus Latina, and also gave dietro and French derrière.[1][13]

Earliest recorded meaning

The TLIO's first record is a Venetian translation of the Pamphilus from about 1250, where the adjective means “placed behind, rear”.[2]

Semantic evolution

As an adjective the word meant “at the back”, also “farther away” and “hind” of animals' legs and of the rear half of a body or a ship;[2][14] Dante's thieves turned into serpents stretch out their hind feet (li diretani alle cosce distese).[2][14] The second main sense was “last”, with set phrases such as deretana unzione “extreme unction”, deretano giudizio “Last Judgement” and deretana volontà “last will”.[2] Boccaccio keeps “the last place” for Dioneo in the Decameron.[15][9]

The noun “backside” appears in Ariosto's Orlando furioso of 1516.[8] Tommaseo already marked the adjective as antiquated, and today it survives in literary use while the noun is the common jocular word.[15][9][10]

Timeline

  • c. 1250 – A Venetian translation of the Pamphilus uses deretano “rear”.[2]
  • 1288 – Zingarelli dates the word to this year.[10]
  • 1516 – Ariosto uses it as a noun, “backside”.[8]
