Pronunciation

  • IPA (Classical): [ˈba.di.ʊs][1]
  • IPA (Ecclesiastical): [ˈbaː.di.us][1]

Forms

badius (feminine badia, neuter badium); first/second-declension adjective[1]

Etymology

It is inherited from Proto-Italic *boþjo-.[2] The ⟨di⟩ points to an original voiced aspirate, as in medius, and de Vaan connects it with Old Irish buide (“yellow”), from Proto-Celtic *bod-io-.[2][3] Because the word is limited to Latin and Celtic and begins with /b/, a PIE origin is unlikely.[2] Wiktionary notes the superficial resemblance to a PIE *bodyos “yellow, brown”.[1]

Earliest recorded meaning

Varro uses it, and it is rare.[2][4] Köbler dates Varro 116–27 BC.[5]

Semantic evolution

In Latin it was a colour of horses, bay or chestnut.[3][4] Palladius and Isidore still use it, and a gloss calls it the colour of a swallow.[6]

Medieval writers used it of bay horses.[7][8] Through Anglo-French bai it gave English bay “reddish-brown”.[9] It survives as Italian baio, French bai and Spanish bayo.[1]

Timeline

  • 116–27 BC – Varro uses it.[2][5]
  • mid-14th century – English bay “reddish-brown” is recorded.[9]

Meanings

Adjective
