Reconstruction

Ringe and Taylor give the nominative singular *brōþer in their Proto-West Germanic paradigm of the r-stems,[1] and Wiktionary has the same form.[2]

Etymology

It is inherited from Proto-Germanic *brōþēr (“brother”),[3][4] which Kroonen cites by its stem *brōþer- and Orel as *ƀrōþēr.[3][4] Fulk assumes a Proto-Germanic nominative *brōþēr, which would explain Old High German bruoder, though the stem *brōþer- of the accusative and vocative, extended to the nominative, would give the same result.[5] In Gothic and Old Icelandic the weak stem of the r-stems spread to all cases but the nominative and accusative singular, while in West Germanic the strong stem prevailed.[5]

Morphology

A masculine r-stem.[1][6] Ringe and Taylor's Proto-West Germanic paradigm has the singular nominative *brōþer, accusative *brōþar, genitive *brōþur (perhaps *brōþuraz), dative-instrumental *brōþri, and the plural nominative *brōþar (with a query), accusative *brōþar, genitive *brōþrō, dative-instrumental *brōþrum.[1] They assume that the dative and instrumental had merged in the singular of the consonant stems as well as in the plural, since no daughter has a distinct instrumental.[1] The early Mercian dative singular brœ̅ðer, West Saxon brēðer, can only continue the inherited form in *-ri, and the old genitive ending survives in brōður.[7] Fulk notes that the plural has no umlaut anywhere in West Germanic, while North Germanic has it, as in Old Icelandic brœðr.[8]

Evidence

The noun is attested in all the West Germanic languages: Old English brōþor, Old Frisian brōther, Old Saxon brōthar, Old Dutch bruother and Old High German bruoder.[9][3] EWA counts it among the kinship terms that have regular counterparts in all the Germanic languages and in almost all the other Indo-European ones.[9] Old Dutch has it in the psalms of the 9th century, glossing Latin frāter,[10] and in Williram's commentary of about 1100.[11] In Old English the vowel of the second syllable varies by dialect: early Mercian brōður, early West Saxon brōðor, Kentish brōðar.[7] EWA explains the vowel of the Old English second syllable by vowel harmony.[9]

Competing analyses

The Proto-Germanic nominative is disputed.[5] The usual view takes the Gothic nominative for a regular outcome of *-ēr;[5] Stiles argues that it took over the stem of the vocative, Hamp, supporting him, posits a nominative *brōþē, and Fulk finds Stiles's analysis quite likely.[5]

Meanings

  1. brother[1][2]

Old Frisian also used the word for a lay brother of a monastery,[12] and Old High German also for a fellow man or a brother in faith or in a religious order.[9]

Derivatives

  • *brōþerlaus "without a brother", which Wiktionary reconstructs;[13] Old English has the adjective brōþorlēas.[14]
  • Orel reconstructs the Proto-Germanic compounds *ƀrōþur-ƀanōn "fratricide", continued by Old English brōþorbana, and *fōstra-ƀrōþēr "foster-brother", continued by fōsterbrōþor.[15][16]

Reflexes

  • Old English: brōþor (“brother”)[14]
  • Old Frisian: brōther (“brother, lay brother”)[12]
  • Old Saxon: brōthar (“brother”)[17]
  • Old Dutch: bruother (“brother”)[11]
  • Old High German: bruoder (“brother, fellow man, brother in faith”)[9]
