Pronunciation

  • Classical: [ˈbruː.nʊs][1]
  • Ecclesiastical: [ˈbruː.nus][1]

Forms

brūnus (feminine brūna, neuter brūnum); first/second-declension adjective[1] Also brūneus and brūnius.[1][2][3]

Etymology

It is borrowed from Old High German brūn (“brown”),[1] from Proto-Germanic *brūnaz;[1][3][4] the MLW and Niermeyer also call it Germanic.[5][2] Köbler connects it with Proto-Indo-European *bʰer- (“shining, brown”).[3] Du Cange reports Octavius Ferrarius' guess that it was named from the colour of plums, prūnum.[6]

Etymonline notes that the Germanic word was adopted into Romance, as Italian bruno, Spanish bruno and French brun.[4][1]

Earliest recorded meaning

Its first author is Constantine the African,[3][5] who says that a hot and dry body has black hair and a brown complexion.[5]

Semantic evolution

In medieval Latin it was used of brown or dark hair and complexions, of animals, and of things such as bread.[5][7] Frederick II's book on falconry describes some saker falcons as brown tending to black.[5] English records use it of horses and cows, as in equus brūnus badius, a brown-bay horse.[7][3] The neuter was used as a noun for brown colour,[5] and Köbler records a noun brūnus for a coarse brown woollen cloth.[3]

Timeline

  • 1020–1087 – Constantine the African uses it of complexion.[5][3]
  • 1086 – Domesday Book has it as a byname.[7]
