Pronunciation

  • Classical: [ˈtɔ.nɪ.trʊs][1]
  • Ecclesiastical: [ˈtɔː.ni.trus][1]

Forms

tonitrus m (genitive tonitrūs); fourth declension[1] The plural is tonitrūs (masculine) or tonitrua (neuter).[2][3] There is also a neuter tonitruum.[3][4] A neuter nominative tonitru rests only on the grammarians.[3]

Etymology

It is a derivative from Latin tonō (“to thunder”).[2][3][1] The OLD suggests an earlier ⟨*tonitus⟩, a noun in ⟨-tus⟩, influenced by fulgetrum (“lightning”).[2] Wiktionary and Köbler trace the verb to Proto-Indo-European *(s)tenh₂- (“to thunder”).[1][5]

Earliest recorded meaning

Köbler dates it from Plautus,[5] who has the nominative tonitrus in the Amphitruo.[4]

Semantic evolution

It means thunder.[2][3][1] Pacuvius has the sky trembling with thunder, and Virgil a speaker who will stir the whole sky with thunder.[4][3] Lucretius and Pliny the Elder speak of hearing thunder, and Cicero of lightning flashes and thunder.[3] It is also an artificial imitation of thunder or a contrivance for producing it, as in Sallust, where a statue of Victory, lowered with the sound of machine-made thunder, placed a crown on someone's head, and in Vitruvius and Phaedrus of stage machinery.[2] It also means a noise like thunder: Pliny the Elder writes of a terrible thunder heard inside when the doors are opened, and Statius and Silius Italicus of the thunder of arms and of a huge shield.[2] Stelten gives "thunder" for Church Latin.[6]
