Pronunciation

  • Classical: [ˈbɪ.jʊ.ɡʊs][1]
  • Ecclesiastical: [ˈbiː.ju.ɡus][1]

Forms

biiugus (feminine biiuga, neuter biiugum); first/second-declension adjective[1] A by-form biiugis is used beside it,[2][3] and a contracted bīgus appears in Manilius.[4][5]

Etymology

It is from Latin bi- (“two”) + iugum (“yoke”).[5][6][1] The TLL derives it from the noun or from iungō (“to join, yoke”) and compares bīgae (“a two-horse chariot”).[7] De Vaan explains such compounds of a numeral and the root of that verb as old o-stems.[8]

Earliest recorded meaning

The TLL takes the -us form to be the older one, found from Lucretius on.[7][6] Lucretius uses it of a pair of yoked lions (biiugōs leōnēs) and of a chariot drawn by two horses.[2][9]

Semantic evolution

Virgil uses it of a chariot race (biiugō certāmine) and, as a plural noun biiugī, of a two-horse chariot from which Turnus leaps down.[2][5][9] Martial uses it of horses, Valerius Flaccus of serpents, and Statius of the pole of a chariot.[4] In metre Terentianus Maurus calls a pair of feet biiugī pedēs.[2]
