Pronunciation

  • Classical: [ˈae̯s.tɪ.fɛr][1]
  • Ecclesiastical: [ˈɛs.ti.fer][1]

Forms

aestifer (feminine aestifera, neuter aestiferum); first/second-declension adjective (nominative masculine singular in -er)[1]

Etymology

It is from Latin aestus (“heat”) + -fer (“bearing”).[2][3][1] The noun aestus belongs with aestās (“summer”), which de Vaan traces to Proto-Italic *aiþ- (“fireplace”) and Proto-Indo-European *h₂(e)idʰ- (“burning”).[4]

Earliest recorded meaning

Lucretius uses it first,[5] of fire that gives off light and heat, and of the hot southern region from which the Nile comes.[2][3]

Semantic evolution

Cicero, in his Aratea, calls the constellation Cancer heat-bringing, and Virgil, Seneca and Statius use it of the Dog Star.[2][3] Lucan and Silius Italicus apply it to the hot lands of Libya, and Statius to the Nile.[2][3] Late poets such as Ausonius, Rutilius Namatianus and Martianus Capella still use it of the stars.[3]

In medieval British verse it describes torrid Syene.[6]

Timeline

  • 96–55 BC – Lucretius uses it of fire and of hot regions.[2][5]
  • 81–43 BC – Cicero uses it of the constellation Cancer.[2][5]
  • 70–19 BC – Virgil uses it of the Dog Star.[2][5]
  • 25–101 AD – Silius Italicus uses it of the sun and of Libya.[2][5]

Meanings

Adjective

  1. That brings or causes heat;[2][7] (of a constellation) bringing hot weather.[2][7]
  2. (of places) Hot, sultry, torrid.[2][7][6]

Usage notes

The grammarian Charisius quotes Pliny as arguing that the right form is aestifer, not aestiferus, like other compounds such as aurifer and armiger.[3]
