Reconstruction

Wiktionary reconstructs *treuwu "fidelity, pledge" for Proto-West Germanic,[1] and Fulk writes the same form.[2] Ringe and Taylor write the Proto-West Germanic stem as *treuwō, with a separate form for the nominative singular.[3]

Etymology

It is inherited from Proto-Germanic *trewwō (“fidelity, agreement”),[3][2] which Orel also writes *trewwō and Köbler *trewō, *trewwō.[4][5] Orel takes it for the adjective *trewwaz used as a noun,[4] and Wiktionary for a noun formed from Proto-Germanic *triwwiz (“true, faithful”).[6] The geminates *jj and *ww of Proto-Germanic became stops in Gothic and Old Norse, the "Verschärfung", as in Gothic 𐍄𐍂𐌹𐌲𐌲𐍅𐌰 (triggwa, “covenant”); in West Germanic the first half of the geminate developed like the second element of a diphthong, through a reanalysis that Ringe and Taylor think happened only once, at the Proto-West Germanic stage.[7][6] Fulk gives *trewwō > *treuwu as an example of the diphthongs that arose as a consequence of the Verschärfung, unless the Verschärfung itself came from an analogical extension of diphthongs rather than a doubling of glides.[2] Ringe and Taylor set beside the noun the adjective *(ga)triuwī "trustworthy", from Proto-Germanic *trewwaz.[3]

Morphology

A feminine ō-stem, in Old English a wō-stem.[8][9] Berr notes that the Old Saxon word is used mostly in the plural.[10]

Evidence

The noun is attested in all the West Germanic languages: Old English trēow, Old Frisian triūwe, Old Saxon treuwa and Old High German triuwa,[3] the Old High German word from before 790,[9] and Old Dutch triuwa, written ⟨truwa⟩ in Williram's commentary of about 1100 and ⟨trivwe⟩ in the Middle Franconian Rhyme Bible.[11] Gamillscheg derives French trêve (“truce”), recorded in the 12th century as Old French trieve, from Frankish *treuwa.[12] Köbler also lists Medieval Latin trewa "obligation, treaty, truce" with this family.[5]

Meanings

  1. fidelity, faith[1][3]
  2. pledge, agreement[1][3]

Old English also used the word for "truth, belief" and "favour",[13] Old Frisian for "promise of marriage",[14] and Old Saxon for "peace" and "alliance".[15]

Derivatives

  • *treuwēn "to be faithful; to trust", which Wiktionary derives from both the adjective and the noun;[16] Köbler derives Old High German triuwēn (“to ally oneself”), recorded from the 9th century, from triuwa.[17]
  • *triuwijan "to make faithful; to trust", which Wiktionary reconstructs from Proto-Germanic *triwwijaną.[18]

Reflexes

  • Old English: trēow (“fidelity, truth, promise, pledge”)[13]
  • Old Frisian: triūwe (“fidelity, promise, agreement”)[14]
  • Old Saxon: treuwa (“fidelity, peace, alliance”)[15]
  • Old Dutch: triuwa (“fidelity”)[11]
  • Old High German: triuwa (“fidelity, faith, agreement”)[9]
