Pronunciation

  • IPA (Classical): [tɛ.nɛˈbroː.sʊs][1]
  • IPA (Ecclesiastical): [te.neˈbrɔː.s̬us][1]

Forms

tenebrōsus (feminine tenebrōsa, neuter tenebrōsum, comparative tenebrōsior, superlative tenebrōsissimus); first/second-declension adjective[1]

Etymology

It is from Latin tenebrae (“darkness”) + -ōsus.[2][1] Tenebrae continues Proto-Italic *temazros, from Proto-Indo-European *temH- (“dark”).[1]

Earliest recorded meaning

Köbler dates its first use to Catullus, 81/79–52/50 BC.[3] Virgil uses it of dark air and of the Underworld's marsh.[4]

Semantic evolution

It meant unlit, dark, gloomy, and Lewis & Short note that it is poetic and found in post-Augustan prose.[2][4] Ovid uses it of Tartarus and a dark cave, and Cicero, in a fragment, of dark stairs.[4][5] Figuratively Tertullian calls a man obscure tenebrosus, and Justinian's Code speaks of a most obscure error.[6]

In Christian and medieval Latin it was dark, without light, bringing darkness, and often figurative.[7] English tenebrous is recorded in the late 15th century, through Old French.[8]
