Forms

ousar (first-person singular present ouso, first-person singular preterite ousei, past participle ousado)[1] Houaiss records oussam in the 14th century and ousarrom and houzaua in the 15th.[2] The Crónica Troiana writes oussaua.[3]

Etymology

It is inherited from Vulgar Latin *ausō (“to dare”), written Old Galician-Portuguese ousar in the oldest texts.[2][4][5] The Vulgar Latin verb was formed on ausus, the past participle of audeō (“to dare”);[4][6] Houaiss and Nascentes call it a frequentative.[2][5] Wiktionary notes that a Late Latin form of the verb is found in a single manuscript, of a grammar attributed to Irish circles of the 7th century.[1] A Latin charter of 1068 already uses its past participle.[3]

The same Latin verb is Galician ousar, Spanish osar, Catalan gosar, Occitan ausar, French oser and Italian osare.[7][8] The Spanish verb is recorded from the end of the 10th century.[9]

That verb was derived from avidus (“greedy”), and first meant “to want very much”; the old polite formula sōdēs (“if you please”), from “if you want”, keeps that sense.[10][1]

Earliest recorded meaning

Lorenzo dates the Portuguese verb to the 13th century.[3] In the Cancioneiro da Ajuda it means “to dare” and takes an infinitive either directly or with a or de; the Crónica Troiana says of a fighter that nobody dared to await his blow (nehun nõno oussaua atender).[3]

Semantic evolution

The construction with a before the infinitive was common in the cantigas d'amigo and has since been lost,[3] though Bluteau still quotes ouso a dizer from 17th-century writers.[11] Aurélio marks the use with an indirect object as obsolete.[12] Beside “to dare”, the verb came to mean “to decide on” and “to attempt something new or difficult”.[2][12]
