Forms

desio m (plural desii)[1] The variant disio is the form of Dante, and desio the form of Guittone and Petrarch that later usage kept.[2][1] Spellings in the early texts include Old Italian dizio, Old Italian dixio and the southern Old Italian disiu.[3]

Etymology

In DELI's account it is inherited from Vulgar Latin *desēdium, at first “erotic desire”, a neuter beside Latin dēsidia (“idleness, sloth”), which was thought to lead to lust.[4][5] Nocentini starts from *desidium, with the vowel of the Latin noun.[6] The LEI reports Castellani's view that Sicilian disiu comes from the form with short ⟨i⟩, and Old Occitan dezieg and Catalan desig from the form with long ⟨ē⟩.[2] Wiktionary cites the Early Medieval Latin dēsideus (“desire”) of a glossary from Italy.[1]

The Latin noun comes from dēsideō (“to sit idle”), from dē- and sedeō (“to sit”).[4][6] Already in Plautus it could mean debauchery, and Wiktionary allows for the influence of dēsīderium (“desire”).[1][2] Nocentini explains the change of meaning by the old idea that idleness breeds the wish for pleasure.[6] The simple verb is from Proto-Indo-European *sed-eh₁- (“to be seated”).[7]

The same word is Spanish deseo and Portuguese desejo.[6][8] Settegast first proposed this source, against Diez's dissidium.[2] Prati found the reconstructed form without a secure basis in Latin.[9] The TLIO calls the etymology uncertain and also cites a Vulgar Latin *desirium.[3] Devoto derived it from dezire crossed with desiderio.[10]

DEI noted that the word does not have Tuscan phonetics and may come from the south.[8] The TLIO takes it as native in Sicilian and carried to the rest of Italy by the lyric poetry of the 13th century.[3]

Earliest recorded meaning

The first record is in Giacomo da Lentini, of the Sicilian school, before 1250, in the sense “desire”: Amor è uno desio che ven da core (“Love is a desire that comes from the heart”).[4][3][11]

Semantic evolution

In Old Italian desio was above all the impulse of love, and also a natural instinct, a person's complete power over someone (avere in desio qualcuno), and joy or eagerness, as in con gran desio.[3] Dante uses disio for the thing or the person desired: ov'è 'l disio de li occhi miei?[2][12] Petrarch and the later poets kept the word for desire: Sì traviato è 'l folle mi' desio.[11]

Derivatives appeared with the noun: desiare and desioso are in Giacomo da Lentini, desiore in Jacopone, desianza in Cino da Pistoia.[4][8][9] Today desio is literary, and in familiar speech it means a delight, often ironically.[12][13][14]

Timeline

  • Before 1250 – Giacomo da Lentini uses desio, desiare and desioso.[4][3]
  • Before 1294 – Guittone d'Arezzo uses the form desio.[2]
  • About 1319 – Dante uses disio for the desired object or person.[2]

Usage notes

Desio is also the first person singular present of the literary verb desiare “to desire”.[4] In Venetian and Friulian desìo means a great quantity or a ruin, as in far un desìo “to wreak havoc”, a word of unclear origin perhaps taken from the Italian noun.[17] Desio is also a comune of Monza, in Lombardy.[1]
