Pronunciation

  • /supˈpor.re/[1]

Forms

supporre (first-person singular present suppóngo, first-person singular past historic suppósi, past participle suppósto or suppòsto, first-person singular imperfect supponévo, auxiliary avére)[1] Older and literary forms are sopporre, soporre and supponere.[2]

Etymology

It is borrowed from Latin suppōnere (“to put under; to substitute”), a compound of sub (“under”) and pōnō (“to put, place”).[3][4][2][1] The infinitive was refashioned on the native porre, as Devoto notes.[5][6] Nocentini glosses the Latin verb “to place under; to suppose”, also in the sense “to substitute by deceit”.[4] Meyer-Lübke and Körting set the learned verb “to make a hypothesis” beside the inherited Old Italian sopporre (“to subject, put under”); Spanish suponer is the same verb, while French supposer was remade on poser.[7][8][4]

De Vaan derives pōnō from an older Proto-Italic *po-sine/o- (“to put down”), a compound of the verb sinō (“to let, allow”): hence the old perfect ⟨posīvī⟩.[9]

Earliest recorded meaning

DELI's first record of the sense “to imagine that something has happened or may happen in a certain way” is an Old Italian translation of Saint Augustine, perhaps of the 14th century, and it notes earlier records of other senses.[3] GDLI quotes Dante's Convivio: Nulla scienza dimostra lo proprio subietto, ma suppone quello (“No science proves its own subject, but presupposes it”).[2]

Semantic evolution

The older senses, “to put under” and “to replace (one person or thing) with another”, are now archaic.[6][10][11] DEI records supporre in the sense “put under, put in another's place” from the 16th century.[12] The sense “to suppose, conjecture” is well attested from Galileo, before 1642.[3] The noun supposizione is recorded before 1406, in Francesco da Buti.[3]

From the participle came supposta, a suppository (before 1320), and in the 20th century supponente “presumptuous, arrogant” (1973) and supponenza (1980).[4]
