Pronunciation

  • Classical: [ˈsaː.ɡʊs][1]
  • Ecclesiastical: [ˈsaː.ɡus][1]

Forms

sāgus (feminine sāga, neuter sāgum); first/second-declension adjective[1]

Etymology

It is probably inherited from Proto-Indo-European *séh₂gos, from the root *seh₂g- (“to seek, track”), which also underlies a verb meaning “to perceive keenly”.[1][2] De Vaan groups it with sāgiō, sāga “wise woman”, sagāx “keen-scented” and praesāgiō “to foresee”, which go back to Proto-Italic *sāg-ije/o- (“to seek, perceive”) and *sag-āk- (“perceptive”); he notes that the compound is attested earlier than the simple forms, which may be back-formations from it, and that the adjective appears only after the Republic.[3] He tentatively sets up a Proto-Indo-European noun *seh₂ǵ-i- (“tracking”), with a question mark.[3]

Cognate with Old Irish saigid (“to try to reach”), Hittite šāgāi- (“omen”), Ancient Greek ἡγέομαι (hēgéomai, “to direct, lead”) and Gothic 𐍃𐍉𐌺𐌾𐌰𐌽 (sokjan, “to search”).[3] The OLD compares Old Irish saigim (“seek”).[4]

Earliest recorded meaning

De Vaan finds it from Statius on.[3] In the Thebaid Statius speaks of the sky that will give no sure sign by sagis clangoribus, the prophetic cries of birds, and in the Achilleid of prophetic birds.[4][5][6]

Semantic evolution

As an adjective it is post-Augustan and rare, while the feminine noun sāga “wise woman, fortune-teller” is common and Classical.[5][3] Besides “prophetic”, Apuleius uses it of women practising witchcraft, who gnaw the faces of the dead.[4][6] An inscription has sagae manus, magic hands.[5][7]

Timeline

  • c. 45–96 AD – Statius uses it of prophetic birds and their cries.[4][5][2]
  • c. 125–175 AD – Apuleius has sagae mulieres, women who practise witchcraft.[4][6][2]

Meanings

Adjective

  1. Prophetic, prescient, divining.[4][5][1]
  2. Practising witchcraft, magical.[4][6][7]

Usage notes

A different word, sagus “military cloak” (genitive sagī), is an archaic and occasional form of sagum, with a short ⟨a⟩.[4][5][1][8]
