Pronunciation

  • Classical: [sɔˈnoː.rʊs][1]
  • Ecclesiastical: [soˈnɔː.rus][1]

Forms

sonōrus (feminine sonōra, neuter sonōrum, adverb sonōrē); first/second-declension adjective[1]

Etymology

It is from Latin sonor (“sound, noise”) + -us.[2][1] De Vaan lists sonor among the derivatives of sonō (“to sound”), which goes back to Proto-Italic *swena- (“to sound”) and Proto-Indo-European *suenH- (“to sound”).[3] Cognate with Old Irish seinnid (“to play an instrument”).[3]

Earliest recorded meaning

Köbler dates it from Virgil,[4] whose Aeneid speaks of the winds and the loud, roaring storms.[2][5]

Semantic evolution

Lewis and Short describe it as poetic and post-Augustan, used in place of the classical sonāns.[6] It means full of sound, loud or resounding:[2][7] Virgil also uses it of rivers,[7][5] the Tibullan corpus of a lyre and Claudian of bronze and a bow.[6] Apuleius uses it of ears that ring or buzz,[2][8] Gellius of a lion's roar and, quoting Pacuvius, of Accius' high-sounding verses.[7][2] Terentianus Maurus uses the feminine as a noun for a consonant.[2][8] Priscian has the comparative.[7]

British medieval writers used it for loud, for sweet or melodious, and for high-sounding diction.[9] English sonorous was borrowed from it in the 1610s.[10]
