Reconstruction

Ringe and Taylor reconstruct *aggju for Proto-West Germanic,[1][2] and Wiktionary has the same form.[3]

Etymology

It is inherited from Proto-Germanic *agjō (“edge”),[1][4] which Kroonen cites as *agjō- and Orel as *aʒjō.[4][5] Fulk likewise derives Old English eċġ from *aggju and that from *aʒjō.[6] The geminate comes from the gemination of most consonants by a following *j, a Proto-West Germanic change that followed the loss of final *-ą and *-az.[7] The *ggj that Old English inherited from West Germanic stayed palatal: *aggju became *æggju and then the Old English word.[1]

Morphology

A feminine jō-stem.[8][9] Ringe and Taylor list it among the ō-stems whose nominative singular ending *-u was later lost in Old English, through *eġġu.[2]

Evidence

The noun is attested in Old English eċġ, Old Frisian egg, Old Saxon eggia and Old High German ecka.[2] Köbler records the Old Saxon word in the Heliand of about 830,[8] and EWA the Old High German one in glosses, in Notker and in the Würzburg boundary description.[9] Old Frisian also has the forms eg, ig, egge and edze.[10] Wiktionary gives only a reconstructed Old Dutch form, *egga.[3]

Meanings

  1. edge[1][3]
  2. corner[3][8]

Old English, Old Frisian and Old Saxon also used the word for "sword",[11][12][8] Old Frisian also for "side" and "party in a lawsuit",[10] and Old High German also for "point" and "border".[9]

Derivatives

  • *aggjōn "to harrow", which Wiktionary reconstructs as formed from the noun with *-ōn;[13] Orel derives a Proto-Germanic verb *aʒjōjanan from the noun, with Old English ecgan (“to sharpen”) and Old Frisian eggia (“to fence”).[14]

Reflexes

  • Old English: eċġ (“edge, corner, sword”)[11]
  • Old Frisian: egg (“corner, edge, blade, sword, side, party”)[12]
  • Old Saxon: eggia (“edge”)[15]
  • Old High German: ecka (“edge, point, corner, border”)[9]
