Reconstruction

Wiktionary reconstructs *feurþō "fourth" for Proto-West Germanic.[1] Orel writes that West Germanic turned *feđurþōn into *feurþōn,[2] and Ringe and Taylor already reconstruct *feurþō̄ for Proto-Northwest Germanic, the source of Old Norse fjórði.[3]

Etymology

It is inherited from Proto-Germanic *fedurþô (“fourth”),[1] which Orel reconstructs as *feđurþōn, derived from the cardinal *feđwōrez, *feđurez "four".[2] Boutkan and Siebinga set up Proto-Germanic *feurþan-.[4]

Morphology

An ordinal numeral.[5][6]

Evidence

The ordinal is attested as Old English fēorþa, Old Frisian fiārda, Old Saxon fiortho and Old High German fiordo.[3][7] Early Old High German also has ⟨feortho⟩.[4] Köbler dates the first Old High German records to the end of the 8th century.[8] Ringe and Taylor note that the Old Frisian outcome ⟨iā⟩ differs from the ⟨ēo⟩ of Old English ⟨fēorþa⟩.[3]

Competing analyses

Wiktionary takes the *d of the Proto-Germanic form to have been removed by analogy with the cardinal *feuwar.[1] Boutkan and Siebinga hold that the word must have lost the first of its two dentals by dissimilation, referring to Stiles.[4]
