Forms
aestuōsus (feminine aestuōsa, neuter aestuōsum); first/second-declension adjective[1]
Etymology
It is from Latin aestus (“heat, swell of the sea”) + -ōsus (“full of”).[2][1][3] De Vaan derives aestus, with aestās (“summer”), from Proto-Italic *aissu- and Proto-Indo-European *h₂eidʰ-tu- (“burning, heat”), with the suffix restored in Latin.[4]
Earliest recorded meaning
The TLL and Köbler record it from Plautus on,[3][5] who in the Bacchides calls a courtesan acerrume aestuosa, seething like a flood that swallows whoever she touches.[2][6]
Semantic evolution
Its commonest sense is very hot, sweltering: Cicero travels on an aestuosa et pulverulenta via, a hot and dusty road, Catullus has hot Nicaea, Horace sweltering Calabria and Pliny the Elder a hot south wind.[2][7][8] Columella uses it of an animal that suffers from heat, the pig, and Pliny of food that heats the body.[2][8] Of water it means seething, raging, as in Horace's fretis aestuosis.[2][6] Conte notes that Horace's Syrtis aestuosas is read both as the burning Syrtes of the desert and as their seething shoals.[8] Lewis and Short cite an adverb aestuōsē, hotly, with its comparative in Horace.[7]
