Latin sāgus

Pronunciation

  • Classical: [prae̯ˈsaː.ɡʊs][1]
  • Ecclesiastical: [preˈs̬aː.ɡus][1]

Forms

praesāgus (feminine praesāga, neuter praesāgum); first/second-declension adjective[1]

Etymology

It is from Latin prae- (“before”) + sāgus (“prophetic, prescient”).[2][1] De Vaan notes that the simple sāgus appears only from Statius on, while the verb praesāgiō (“to foresee”) is found from Plautus; he reconstructs Proto-Italic *sāg-ije/o- (“to seek, perceive”), perhaps from Proto-Indo-European *seh2ǵ-i- (“tracking”).[3]

Earliest recorded meaning

It is first found in Virgil's Aeneid,[4] in the phrase “praesaga mali mens”, a mind foreboding evil, and of the fires of a lightning flash that foretell what is to come.[2][5]

Semantic evolution

It belonged to poetry and post-Augustan prose:[5] it meant either feeling a presentiment, of the heart or mind, or portending and ominous, of signs, words, stars and oracles.[2] Ovid, Lucan, Statius and Silius use it in both senses, and Tacitus speaks of ominous responses.[2] The Vulgate speaks of a dream that foretold the future,[5] and Chalcidius used praesāgus as a noun, a prophet.[6][4]

Medieval writers kept it for a mind with a foreboding, and British sources also used it for one who imparts foreknowledge and, as a noun, for a prognosticator.[7]
