Pronunciation

  • Classical: [ˈɪn.wi.ʊs][1]
  • Ecclesiastical: [ˈiɱ.vi.us][1]

Forms

invius (feminine invia, neuter invium); first/second-declension adjective[1]

Etymology

It is from Latin in- + via (“road, way”) + -us.[2][1] De Vaan traces via to Proto-Italic *wijā- (“road”) and Proto-Indo-European *uih₁-eh₂- (“pursuit”).[3]

Earliest recorded meaning

Köbler dates it from Virgil,[4] who has hunters coming into the high mountains and the trackless lairs of beasts.[2]

Semantic evolution

It means without a road, impassable, of country and of paths;[2][5] Lewis & Short note that neither Cicero nor Caesar uses it.[2][5] Livy uses the neuter as a noun, of soldiers led through steep and almost pathless places.[2] It is also inaccessible, as Ovid's temples closed to the profane, and of things impenetrable.[2] In Church Latin invium is a wasteland or desert.[6]

Timeline

  • 70–19 BC – Virgil of trackless lairs and a long pathless way.[2][4]
  • 59 BC–17 AD – Livy of pathless places.[2][4]
  • 43 BC–18 AD – Ovid of inaccessible temples.[2][4]
