Reconstruction
Ringe and Taylor reconstruct *dag for Proto-West Germanic,[1] and Wiktionary has the same form.[2]
Etymology
It is inherited from Proto-Germanic *dagaz (“day”),[3][4] which Kroonen cites by its stem *daga- and Orel as *đaʒaz.[4][5] Ringe and Taylor derive Proto-West Germanic *dag, *dagas, *dagē from the Proto-Germanic nominative, genitive and dative *dagaz, *dagas, *dagai.[6] The loss of word-final *-z in polysyllables and of word-final short low vowels left the nominative singular without an ending.[1]
Morphology
A masculine a-stem.[7][8] Ringe and Taylor's Proto-West Germanic paradigm has the singular *dag (nominative and accusative), *dagas (genitive), *dagē (dative) and *dagu (instrumental), and the plural *dagō and *dagą̄ (nominative and accusative, both marked as uncertain), *dagō (genitive) and *dagum (dative-instrumental).[1] The *-s of the Old English and Old Saxon nominative plural, dagas and dagos, might be later than Proto-West Germanic; both languages gave the accusative plural the form of the nominative, while Old High German taga did the reverse.[9] In Old English the fronted vowel was retracted to a in all and only the forms of the plural, because of the shapes of their endings.[9]
Evidence
The word is found in all the West Germanic languages: Old Saxon dag and Old High German tag keep the vowel, while Old English dæġ and Old Frisian dei show the fronting of short *a in the northern dialects.[3] De Vaan derives Old Frisian dei from *dæg, with the palatalization of the final consonant.[10] Old Dutch has dag, as ⟨dach⟩ in Williram's commentary of about 1100 and ⟨dage⟩ in the Middle Franconian Rhyme Bible.[11] Klingenberg read a single d-rune at the end of a line of the Schretzheim II inscription as a concept rune for pre-Old High German *d(ag), taken as a man's name;[12] Düwel, Nedoma and Oehrl call this a mere conjecture.[12]
Competing analyses
De Vaan counts the fronting of West Germanic *a to æ among the Anglo-Frisian characteristics, and since Proto-Frisian merged *æ with *e before 700 CE, Proto-Frisian had *dej where Proto-Franconian had *dag.[13] On that basis several authors have taken western Dutch forms with e for traces of an Ingvaeonic stage of coastal Dutch.[13] Stiles puts the fronting of *dag to *dæg early in the relative chronology of the Anglo-Frisian sound changes, before the palatalization of velars.[14] Ringe and Taylor treat the fronting as a change of the northern West Germanic dialects.[3]
Meanings
Old English also used the word for "weekday",[7] Old Frisian also for "lifetime", "appointed day" and "assembly",[15] and Old High German also for "time".[16]
Derivatives
- *dagēn "to dawn", which Wiktionary reconstructs;[17] Ringe and Taylor reconstruct *dagē- behind Old High German tagēn, remade in Old English as the class II verb dagian.[18]
- The weekday names *Sunnōn dag "Sunday" and *Wōdanas dag "Wednesday", which Wiktionary reconstructs as calques of the Latin names;[19][20] de Vaan finds the name of Wodan's day both as *Wōdanas *dag and as *Wōdinas *dag, without and with i-mutation.[21]
