feigr

• fæigʀ — Old East Norse
• ᚠᛆᛁᚴᛁᚭᚿ (faikiąn) — Rök runestone (strong masculine accusative singular)

From Proto-Germanic *faigijaz, whence also Old English fæġe (English fey)), Old High German feigi (“cowardly”).

• (12th century Icelandic) IPA^(key): /ˈfɛiɣr̩/

feigr

1. fey, doomed to die

The original paradigm inherited from Proto-Germanic was a ja-stem, but already by classic written Old Norwegian-Icelandic it had shifted to a regular a-stem, thus with accusative feigan. However, on the 9th century Swedish Rök runestone we find the form faikiąn (normalized spelling fęigjan), with the ja-stem declension still intact.
