Reconstruction

Wiktionary reconstructs *kraftu for Proto-West Germanic.[1]

Etymology

It is inherited from Proto-Germanic *kraftuz (“strength, power”),[1] which Kroonen cites as the tu-stem *kraftu-, Köbler as *kraftu-, *kraftuz, and Orel as *kraftiz.[2][3][4] Wiktionary analyses the noun as Proto-Germanic *krafjaną (“to demand”) with the suffix *-þuz,[5] and Orel too derives it from *krafjanan.[4] Kroonen calls it possibly related to the verb *krabēn- "to urge, to demand", which has no certain etymology.[2]

Morphology

The daughters differ in gender and stem class: the Old High German word is a feminine i-stem,[6] and so is the Old Dutch one.[7] The Old Saxon word is feminine or masculine, with i-stem, a-stem and consonant-stem forms;[8] the Old Frisian one is masculine and perhaps feminine;[9] the Old English one is masculine, with a-stem and i-stem forms.[10]

Evidence

The noun is attested in all the West Germanic languages: Old English cræft,[10] Old Frisian kreft, also kraft,[9] Old Saxon kraft, often in the Heliand,[11][12] Old Dutch kraft in a psalter source that Köbler dates to the 9th century,[7] and Old High German kraft, recorded from the 8th century.[6] Outside West Germanic it has Old Norse kraptr and krǫptr.[6]

Competing analyses

Kroonen and Wiktionary reconstruct a Proto-Germanic stem in *-u-.[2][5] EWA sets up Proto-Germanic *krafti-, feminine or masculine, and derives only the Old Norse words from *kraftu-;[6] Orel too has an i-stem, *kraftiz,[4] and Köbler traces the Old Frisian and Old Saxon words to *krafti- beside *krafta-.[13][12]

Meanings

  1. strength, power[1]
  2. skill[1]

Old English also used the word for "art, skill, trade, cunning",[10] Old Saxon for "host, troops",[8] Old Frisian for "validity",[9] and Old High German for "virtue" and "multitude".[6]

Derivatives

  • *kraftīg "full of strength, powerful", which Wiktionary reconstructs;[14] Old English cræftig, Old Saxon kraftag and Old High German kreftīg continue such an adjective.[15][11][16]
  • *kraftijan "to strengthen; to build", which Wiktionary reconstructs;[17] Old English cræftan (“to practise an art, to build”) and Old High German kreften (“to strengthen”).[18][19]

Reflexes

  • Old English: cræft (“strength, power, art, skill”)[10]
  • Old Frisian: kreft (“strength, validity”)[9]
  • Old Saxon: kraft (“power, might, host”)[8]
  • Old Dutch: kraft (“strength, power, virtue”)[7]
  • Old High German: kraft (“strength, power, virtue”)[6]
