Reconstruction

Wiktionary reconstructs *blāu "blue" for Proto-West Germanic.[1]

Etymology

It is inherited from Proto-Germanic *blēwaz (“blue”),[1][2] which Kroonen cites by its stem *blēwa- and Orel as *ƀlēwaz,[2][3] while Köbler gives both *blēwa- and *blǣwa-.[4] The root vowel shows the shift of Proto-Germanic *ǣ (*ē₁) to *ā, the first of the sound changes that Düwel, Nedoma and Oehrl list for the southern West Germanic phoneme system.[5]

Morphology

An adjective,[2] a wa-stem in Old High German.[6]

Evidence

The adjective is attested as Old Frisian blāu, Old Saxon blāo and Old High German blāo.[6] Old Saxon has it only in two glosses for Latin lividus, the dative ⟨blauuemo⟩ and the accusative plural ⟨blauuon⟩.[7][6] ONW records Old Dutch only as a reconstructed *blāo, taken from the FEW.[8] Kroonen and Wiktionary give an Old English blāw,[2][1] but EWA finds the word in Old English only in blǣhǣwen (“light blue”) and blǣwen, and takes Middle English blo and blā for Scandinavian loans.[6][9] Late Latin blavus, first in Isidore of Seville and in glosses of the 8th and 9th centuries, and Old French blo, bleu were borrowed from Frankish *blāo (“blue, lead-coloured”).[10][11][6]

Meanings

  1. blue[1][2]

Old High German also used the word for "dark", "grey" and "lead-coloured",[6][12] Old Saxon for "pale" and "livid",[7] and Old Frisian used it as a noun for "bruise".[13]

Reflexes

  • Old Frisian: blāu (“blue”)[14]
  • Old Saxon: blāo (“blue, pale, livid”)[7]
  • Old High German: blāo (“blue, dark, grey, lead-coloured”)[6]
