Pronunciation

  • IPA (Classical): [ˈae̯s.tʊs][1]
  • IPA (Ecclesiastical): [ˈɛs.tus][1]

Forms

aestus m (genitive aestūs); fourth declension[1] Pacuvius has the genitive aestī.[2][3]

Etymology

It is inherited from Proto-Italic *aissu-, from Proto-Indo-European *h₂eidʰ-tu- (“burning, heat”), beside aestās (“summer”).[4][2][1] Most handbooks take ⟨-st-⟩ as the regular outcome of ⟨*-dʰt-⟩, but de Vaan expects ⟨-ss-⟩ and thinks the suffix ⟨-tu-⟩ was restored.[4][1] The root is that of aedēs (“temple, house”), cognate with Old Irish áed (“fire”), Ancient Greek αἴθω (aíthō, “to burn”) and Old High German eit (“funeral pyre”).[4][3][5]

Earliest recorded meaning

De Vaan and Köbler date it from Naevius,[4][6] who has sōlis aestū candor cum liquēsceret, “when the white snow melted in the heat of the sun”.[2]

Semantic evolution

Aestus is “heat”, especially of the weather, a hot season, “summer”, and the heat of the body, “fever”.[2][1] It is the blaze of a fire (Virgil: furit aestus ad aurās, “the blaze rages up to the sky”), and the fire of love or rage.[2][1] Lucretius uses it for a spray or exhalation rising from water.[2] Another main line is the heaving of the sea, “surge, swell” (Pacuvius: fervit aestū pelagus), and the ebb and flow of the sea, “the tide” (Plautus: the farther you go out to sea, the more the tide carries you back to port), then a current and figuratively a tide of feeling (Cicero: carried off by a tide of glory).[2][3][1] It is also commotion, and anxiety, disquiet (Cicero: quī tibi aestus … erunt!).[2][1]

Church Latin glosses it “heat, rage, fire, wavering”.[7]
