Pronunciation

  • Classical: [ˈtrɪ.dẽːs][1]
  • Ecclesiastical: [ˈtriː.dens][1]

Forms

tridēns (genitive tridentis); third-declension one-termination adjective[1]

Etymology

It is a compound from Latin tri- + dēns, “having three teeth”.[2][3][4] De Vaan traces dēns (“tooth”) to Proto-Italic *dent- and Proto-Indo-European *h₃d-nt- (“tooth”).[5] The noun “trident” is the adjective used substantively.[2][6]

Earliest recorded meaning

Virgil (70–19 BC) is the first author with it:[4] in the Aeneid it describes the three-pronged beaks of ships,[7][8][9] and in the Georgics it names Neptune's trident.[8][9]

Semantic evolution

As an adjective the word stayed mostly poetic: Valerius Flaccus also uses it of a ship's beak.[7][8] As a noun it was the three-pronged spear used in fishing,[2][10] which Pliny the Elder mentions,[2] the attribute of Neptune in Ovid,[8][9] and the weapon of the gladiator called retiarius.[2][8] The Vulgate uses it of a three-pronged fork,[10][11] and medieval British writers applied it figuratively too.[11] English trident comes from the noun.[6]
