PERMANENT DISPUTE RECORD
ALL DISPUTES ↗One scholarly question. Every attached source. The present editorial state, without pretending the last word has been written.
Not as a simple word-to-word descent. Fiend continues Old English fēond, the lexicalized Germanic one-who-hates formation; fēogan continues the related verb base.
/ˈfeːo.ɣɑn/ · Old English verb
An Old English verb meaning hate or persecute, recorded as FEÓGAN, feógean, fiógan, contracted feón and fión, with participle feógende and a broad present-and-past paradigm. Bosworth–Toller supplies examples whose objects include crimes, evil ways, law, peace, a temple, friends, and people. The verb continues reconstructed Proto-Germanic *fi(j)ēn-. Its active-participial formation lexicalized prehistorically as the enemy noun behind Old English fēond and modern fiend, but the verb, participle, and noun are not one interchangeable category.
