Reconstruction

The adjective is *brūnaz in Wiktionary,[1] *ƀrūnaz in Orel,[2] *brūna- in Köbler, who also gives *brūnaz, and in Heidermanns.[3][4]

Etymology

Wiktionary tentatively derives it from Proto-Indo-European *bʰerH- (“grey, brown”).[1] Köbler sets up a PIE *bʰrouno- or *bʰrūno-.[3]

Morphology

A primary adjective with the stem *brūna-.[4] Heidermanns finds nothing comparable with the same root grade within Germanic.[4]

Evidence

The adjective is attested in North and West Germanic only.[4] Orel cites Old Norse brúnn, Old English brūn, Old Frisian brūn, Old Saxon brūnrōd (“sparkling red”) and Old High German brūn.[2] Old Saxon has it only in compounds.[4] Köbler sets up a Gothic *brūns on the evidence of Italian bruno.[5] The word was borrowed early into neighbouring languages;[4] de Vries names Finnish ruuni among the loans from the Norse word.[6]

Competing analyses

Orel compares Ancient Greek φρῦνος (phrûnos, “frog”), as "the brown one", and further an IE *bhreu-.[2] Heidermanns allows the Greek match if the animal was named after its colour, but finds the Sanskrit word for "brown" closest as a colour word.[4] Orel separates a second adjective "shining", behind Old Norse brún (“edge”) and Old English brūn (“shining, flashing”).[2] De Vries, after Dal and Krogmann, also takes Old Norse brúnn "shining, sharp" as a different word.[6] Heidermanns treats them as one adjective: the sense "sharp" is only North Germanic and may come from Old Norse brýna (“to sharpen”).[4]

Meanings

  1. brown[3][1]
  2. sparkling, red-brown[4]

Old English also used it for "dark" and "shining",[7] and Old High German for "dark" and "black-brown".[8]

Derivatives

  • *brūnjan "to brown, to adorn", behind Old High German brūnen.[9]
  • *rauđa-ƀrunaz "red-brown", a compound with *raudaz.[10]
