Reconstruction

Wiktionary reconstructs *Mānini dag "Monday".[1]

Etymology

Wiktionary takes it as formed from Proto-West Germanic *Mānini (“the Moon's”) + *dag (“day”), with the genitive of the word for "moon".[1] EWA calls Old High German mântag a determinative compound and a loan translation of Latin diēs Lūnae (“day of the Moon”), which was itself formed after the Greek name of the day, and it sets up the compound as Proto-Germanic *mēnan-đaǥa-, literally "moon day".[2]

Morphology

A masculine a-stem.[2][3]

Evidence

The name is attested as Old English mōnandæg,[3] Old Frisian mōnandei, also mōnendei and mānendei,[4] and Old High German mântag, from about 1000 and in glosses.[2][5] EWA records the Old Dutch Mānodag only from 1136.[2] The word reached North Germanic through West Germanic, as Old Norse mánudagr and mánadagr.[2] Wiktionary gives the Old Saxon form only as a reconstruction.[1]

Competing analyses

The Old English and Old Frisian forms with ō against Old High German ā show one of the Ingvaeonic features that Stiles lists, the backing of long and short *a before nasals, with his example Old English mōna (“moon”) against Old High German māno.[6] The traditional approach takes these features for innovations after Proto-West Germanic, High German being conservative in many respects.[6]
