Forms

Etymology

It is borrowed from Ancient Greek δελφίς (delphís, “dolphin”), also ⟨δελφίν⟩.[2][1][3][4] Köbler compares Ancient Greek δελφύς (delphús, “womb”).[5] The poets also use the Greek form ⟨delphīn⟩.[2][6]

Earliest recorded meaning

The OLD's earliest citation is from Accius, of dolphins.[2] Köbler dates Accius 170–c. 90 BC.[5]

Semantic evolution

It meant a dolphin, as in Accius, Cicero and Horace's dolphin painted in the woods.[2][7] In Columella it was the constellation Dolphin, and in Pliny the Elder and Juvenal an ornament shaped like a dolphin.[2][7]

Medieval Latin used delphīnus as the surname of the counts of Albon, then for a dignity in the Dauphiné, and after 1349 for the eldest son of the kings of France.[8][4] It survives in Italian delfino and French dauphin, and Medieval Latin dolfīnus and Old French daulphin gave English dolphin in the mid-14th century, and French gave English dauphin.[1][4]

  • 170–c. 90 BC – Accius uses it of dolphins.[2][5]
  • 81–43 BC – Cicero uses it.[2][5]
  • 1349 – delphīnus becomes the title of the French heir.[8][4]
