Pronunciation

Forms

oser[1] Old French auser (about 980), oser from 1080.[2][3]

Etymology

It is inherited from Late Latin ausāre (“to dare”), formed on “ausus”, the past participle of audeō (“to dare”).[4][5][6][2][1][7] Bloch and Wartburg explain the new verb by the irregularity of “audēre”, whose perfect was “ausus sum”; the regular first-conjugation type was easier.[6] Rey connects “audeō” with avidus (“greedy”) and an original sense “to desire, be willing”, still seen in the polite formula “sī audēs” (shortened to “sōdēs”) “if you please”.[5] The same Latin family gave audace and avide.[8][5]

Cognate with Italian osare, Old Occitan ausar, Spanish osar and Portuguese ousar.[9][8]

Earliest recorded meaning

In the Passion de Clermont (late 10th century) it means “to have the courage to”: il no l'auseren deramar; the Chanson de Roland has ki l'osast querre.[4]

Semantic evolution

Early in the 12th century it also meant “to have the effrontery to”, especially in a challenge or threat (vous ne m'oseriés pas suirre, early 13th century, si tu l'oses!).[4][5] From 1485 it is used as a polite precaution, j'ose dire; the absolute use, “to be bold”, especially in love, is found in 1480.[4][5] With a noun object, oser quelque chose “to venture on”, it dates from 1561.[4] The participle osé meant “bold” in Wace (about 1155); “risky” (1823) and “daring, risqué” (1856; of a remark, Maupassant 1885) are 19th-century.[4][5] In Switzerland oser means “to be allowed to” (1724).[5][1]
