ausus m (genitive ausūs); fourth declension[1]
Etymology
It is from Latin audeō (“to dare”), formed with the suffix of verbal nouns -tus.[2][3][1]
Earliest recorded meaning
Georges cites the phrase ductu ausuque suo (“under his own leadership and on his own initiative”) from the Bellum Alexandrinum.[4] The TLL treats Petronius as the first author to use it; in the poem on the civil war in the Satyricon he has the plural insolitos ausus, unaccustomed ventures.[3][5]
Semantic evolution
The word means daring and initiative, and in the plural ventures or bold undertakings.[2] After Petronius it is mostly used disapprovingly, often of the audacity of people acting against the law,[3] as in the Theodosian Code's ausu gravi atque damnabili (“with a grave and damnable presumption”).[4] Symmachus and the laws of the emperors Leo and Anthemius also have it.[6][5]
Medieval Latin used it for daring and for a daring deed,[7] in a bad sense for an outrage or for insolence, in a good one for courage and confidence;[8] Walahfrid Strabo already has it in his poem on his garden.[8]
