Forms
astus or āstus m (genitive astūs); fourth declension[1]
Etymology
The origin is uncertain.[2][3][4] Vendryes proposed that it is from Latin astō (“to stand by”), as a u-stem noun Proto-Italic *ad-stu-, from Proto-Indo-European *-sth₂-u- (“a standing by”), comparing the adverb praestō (“at hand”), which appears in some inscriptions as ⟨praestū⟩.[4][1] Ancient grammarians derived it from Ancient Greek ἄστυ (ástu, “town”), since those who live in a town seem shrewd and sharp;[4][3] Ernout and Meillet thought the Greek derivation might reflect a pun modelled on urbānē (“wittily”), but de Vaan notes that the adverb took this sense only after the Old Latin period.[4][3]
Earliest recorded meaning
Plautus has it first; from Plautus to Ovid only the ablative astū is found.[4][5]
Semantic evolution
It means cunning, craft or guile, mostly in the ablative astū, used almost as an adverb, “by craft”, and good or bad in tone.[2][1] Other cases appear after Ovid, and especially in the plural it is a trick or stratagem, as Seneca has Ulysses weaving tricks in his crafty heart.[2] Servius glosses astū as malice and says that we properly call malicious people astūtī.[3] Church Latin glosses it cleverness or cunning.[6]
Timeline
- c. 250–184 BC – Plautus has the ablative astū.[4][5]
- 4 BC–65 AD – Seneca of the tricks of Ulysses.[2][5]
