Pronunciation

Forms

osare (first-person singular present òso, first-person singular past historic osài, past participle osàto, auxiliary avére)[1] Old northern Italian had Old Italian olsare, with a hypercorrect /l/ typical of Lombard and Venetian, and Old Italian alsare only in the Veneto and in Ladin.[2] Other old forms are Old Italian ossare in the north and Old Italian ausare in the Veneto and the south.[2][3]

Etymology

It is inherited from Late Latin ausāre (“to dare”), a verb formed on Latin ausus, the past participle of audeō (“to intend; to dare”), or on the noun ausum (“a daring deed”) taken from it.[4][5][2][1] Wiktionary calls it a frequentative and Devoto–Oli an intensive of the Latin verb.[1][6]

The verb belongs to western Romance: French oser (from about 1148), Occitan ausar, Catalan gosar, Spanish osar (late 10th century) and Portuguese ousar.[5][7][2] The /g/ at the start of the Catalan form is unexplained.[8] The base verb itself left only a rare popular Old Italian odere in the 14th century, beside the learned Old Italian audere (before 1276) and the Tuscan form aldere.[9]

De Vaan derives the base verb from avidus (“greedy”): it first meant ‘to want very much’, as Plautus's sōdēs (“if you please”), from ⟨sī audēs⟩, still shows, and then ‘to dare’.[10] Nocentini puts it in the family of avēre (“to desire”), the source of avaro.[5]

Earliest recorded meaning

The LEI's first record is Giacomo da Lentini, about 1250, with an infinitive: ‘to have the courage or the audacity to do something’;[2][11] Zingarelli also dates it before 1250.[2][11] The Venetian Proverbia quae dicuntur super natura feminarum (about 1250) and the Sicilian King Enzo have the form ausar.[2] DELI's first records are Dante (1300–1313) and P. Martelli (before 1301).[4]

Semantic evolution

In Dante's Inferno the poet non osava scender de la strada / per andar par di lui (“did not dare go down from the path to walk beside him”).[12][13] The verb was at first intransitive, with an infinitive; the transitive use with an object, ‘to attempt’, is recorded from the 16th century.[7] Varchi already wrote osarono di with the preposition.[12]

Today it is also used to soften a statement (oserei dire ‘I would venture to say’) and in the reproach come osi? ‘how dare you?’.[14][6][13] The past participle osato is a rare rendering of French osé, which Italian also borrowed as ⟨osé⟩;[13][2] Giovio's a osadas ‘certainly’ is a Spanish loan.[13][2] Tommaseo noted that ardire says more than osare.[12][13]
