Reconstruction

Wiktionary reconstructs *Frījā dag "Friday".[1] Ringe and Taylor reconstruct its first part, the genitive *Frījā, from Old English Frīġedæġ and Old High German Frīatag.[2]

Etymology

It is formed from Proto-West Germanic *Frījā (“Frija's”) + *dag (“day”).[1][2] EWA dates the name to the 4th century, modelled on Late Latin Veneris diēs, which itself translates the Greek name of the day.[3] Its first part is the name of the goddess, Old High German Friia, whose Old Norse counterpart is the wife of Odin; her role was comparable with that of the Roman goddess of love.[3] Ringe and Taylor trace *Frījā to the Proto-Germanic genitive singular *Frijjōz "of the goddess of marriage", Old Norse Friggjar.[2] Where Gothic and Old Norse turned the geminate *jj into a stop, West Germanic treated its first part like the second element of a diphthong, and *ijj was reanalysed as *īj;[4] Ringe and Taylor take this to have happened only once, at the Proto-West Germanic stage.[2]

Morphology

A masculine a-stem.[5][3]

Evidence

The name is attested as Old English Frīgedæg,[5] Old Frisian frīadei, also frīendei and frēdei,[6] and Old High German frīatag, from the 9th century, in Tatian, Otfrid and glosses.[3] EWA calls it the common Germanic name of the sixth day of the week, but takes Old Norse frjádagr for a loan from West Germanic, probably from Old Frisian or Old English, because of its form.[3] In Bavarian the day was instead called pferintag, a loan from Greek through Gothic.[3] Wiktionary gives the Old Saxon form only as a reconstruction.[1]

Meanings

  1. Friday[1][2]

Old High German also used the word for the day of preparation before the Sabbath.[7]
