Reconstruction

Wiktionary reconstructs *failī "true, friendly, familiar, good" for Proto-West Germanic.[1]

Etymology

It is inherited from Proto-Germanic *failijaz (“true, friendly, good”),[2] which Köbler writes *failja-, *failjaz "familiar, good" and calls of unknown origin.[3] Wiktionary too calls the origin uncertain.[2] EWA traces the Old High German, Middle Low German, Middle Dutch and Old Frisian adjectives for "for sale" to a Proto-Germanic adjective and finds no convincing connection beyond it.[4]

Morphology

An adjective, a ja-stem in Old English and Old High German.[5][4]

Evidence

Old English has fǣle "faithful, good, dear", with the negative unfǣle (“bad”).[5][6] Old Frisian has fēle "for sale", used of a troop serving for pay.[7] Old High German has feili "for sale", glossing Latin vēnālis, from the 9th century and only in glosses.[4] Wiktionary gives the Old Saxon and Old Dutch forms only as reconstructions.[1]

Competing analyses

Old English has the senses "faithful, good", while Old Frisian and Old High German have "for sale".[5][7][4] Köbler puts both under one Proto-Germanic adjective.[3] EWA's list of the words that correspond to the Old High German adjective names Middle Low German, Middle Dutch and Old Frisian, not Old English.[4] Wiktionary itself glosses the adjective "venal, to be sold" where it derives *failōn from it.[8]

EWA reports that the Old High German adjective is generally connected with Old High German fāli (“for sale”), though the vowels are held to be difficult: de Vries assumed a secondary sound change, Seebold a derailment of the ablaut on the German side, while Matzel separates the two adjectives.[4] EWA itself offers, as a vague possibility, a connection with a root meaning "to be fat", a pre-Proto-Germanic *poi̯li- "swelling (after fattening)", said of cattle and pigs, being understood as "for sale".[4]

Meanings

  1. true, faithful, good[1]
  2. friendly, familiar[1]

The continental and Frisian words mean "for sale".[4]

Derivatives

  • *failōn "to sell, to offer for sale", which Wiktionary reconstructs from the adjective with the suffix *-ōn and finds in Middle Low German and Middle Dutch.[8]
  • Köbler sets up Proto-Germanic *failīgaz (“protected, safe”), behind Old Frisian fēlich (“safe”), and Proto-Germanic *failisōn (“to cleanse”), behind Old English fǣlsian (“to atone, to purify”), and refers both to *failja-.[9][10]

Reflexes

  • Old English: fǣle (“faithful, good, dear, precious”)[5]
  • Old Frisian: fēle (“for sale, serving for pay”)[7]
  • Old High German: feili (“for sale”)[4]
