Pronunciation

  • Classical: [ˈbɪ.peːs][1]
  • Ecclesiastical: [ˈbiː.pes][1]

Forms

bipēs (genitive bipedis); third-declension one-termination adjective[1]

Etymology

It is from Latin bi- (“two”) + pēs (“foot”), “two-footed”.[2][1][3] De Vaan calls it the earliest attested compound in ⟨bi-⟩, which goes back to Proto-Indo-European *dui- (“two”); pēs continues Proto-Indo-European *pōd-s.[4] It corresponds to Ancient Greek δίπους (dípous) and to Umbrian dupursus (“bipeds”), which preserves the ablaut grade with long /o/.[2][4]

Earliest recorded meaning

Its first use is in Naevius,[4][5] of birds as two-footed creatures.[6]

Semantic evolution

It is mostly poetic or post-Augustan.[7] Cicero uses it of a two-footed god and, as a noun, contemptuously of people.[6][8] Virgil's two-footed horses are the sea horses of the sea gods, with fishes' tails,[6][8] and Juvenal's two-legged ass is a fool.[8][6] Martial uses it of a table with two legs.[7] Pliny the Elder uses bipedes with verbs of walking for four-footed animals that walk on two feet, such as bears and the mice of Egypt.[2][7] In the Vulgate the plural is a noun, two-footed creatures, set beside the four-footed.[6]

Medieval British writers kept it for two-footed beings, Gerald of Wales in the definition of man.[9] English formed biped from it in the 1640s, as a noun for an animal with two feet.[10]
