Reconstruction

Ringe and Taylor reconstruct *fast "fixed, fast" for Proto-West Germanic,[1] and Wiktionary has the same form.[2]

Etymology

It is inherited from Proto-Germanic *fastuz (“firm, fixed”),[2][3] which Ringe and Taylor write *fastaz, Kroonen *fastu- and Heidermanns *fasta-.[4][3][5] Old English fæst and Old Frisian fest show the fronting of the vowel that Ringe and Taylor illustrate with this word, while Old Saxon and Old High German keep fast.[4]

Morphology

An adjective.[1] EWA notes that a ja-stem is found only in High and Low German, Old High German festi and a single Old Saxon festi, while all the other records are a-stems, perhaps originally u-stems;[6] Old High German fast is an a-stem found only in a few Middle Franconian sources.[6] Wiktionary reconstructs *fastī as a variant of *fast, formed with the adjective suffix *-ī.[7]

Evidence

The adjective is attested as Old English fæst, Old Frisian fest, Old Saxon fast and Old High German fast,[1] and Old Dutch fast (“fortified”) glosses Latin munitus in the Old Low Franconian psalms of the 9th century.[8] ONW has it also in Williram's commentary of about 1100.[9] It is common Germanic, but in Gothic it is found only indirectly.[5][6]

Competing analyses

The stem class of the Proto-Germanic adjective is disputed.[6] Kroonen reconstructs a u-stem, remodelled as a ja-stem in West Germanic, and connects it with Old Armenian հաստ (hast).[3] Ringe and Taylor reconstruct an a-stem *fastaz.[1][4] Heidermanns denies that the East Norse form ⟨fæster⟩ "promised" is evidence for a u-stem, since it is the past participle of a verb.[5] EWA finds the ja-stem only in High and Low German, and the a-stem everywhere else.[6]

Meanings

  1. fixed, fast[1][2]
  2. firm[4]

Old English also used the adjective for "strong, secure, constant",[10] Old Frisian for "reliable" and "honourable",[11] and Old Saxon for "steadfast, unshakeable" and "fettered".[12]

Derivatives

  • *fastinōn "to fasten securely, to make fast": Old English fæstnian, Old Frisian festnia, Old Saxon fastnon, Old High German festinōn.[1]
  • *fastijan "to fasten", which Wiktionary reconstructs;[13] Old English has fæstan (“to fasten, to entrust”) and Old Saxon festian (“to fasten”).[14][15]
  • *fastēn "to fast", which Wiktionary reconstructs;[16] Heidermanns reports that Seebold separates the verb for "to fast" entirely from the adjective.[5]
  • Compounds in *-fast that Wiktionary reconstructs from Old English and Old Saxon: *sanþafast "honest, true", *wārafast "faithful" and *legrafast "ill";[17][18][19] Köbler lists Old Saxon compounds with ⟨legar-⟩, ⟨sōth-⟩ and ⟨wār-⟩.[12]

Reflexes

  • Old English: fæst (“firm, strong, secure, constant”)[10]
  • Old Frisian: fest (“firm, secure, reliable”)[11]
  • Old Saxon: fast (“firm, steadfast, secure”)[12]
  • Old Dutch: fast (“firm, fortified”)[9][8]
  • Old High German: festi (“firm, strong, fortified, secure”)[6]
