Old Norse fjá was a verb meaning to hate. The Dictionary of Old Norse Prose classifies it as poetic and exposes zero prose citations; its glossarium links point to the early form fía and the reconstructed Proto-Germanic *fi(j)ēn-. Cleasby and Vigfússon call the verb obsolete, compare Gothic fijan and Old English feon or fjan, and locate it in Hýmiskviða 22 and Lokasenna 35, with the reflexive fjásk in Skírnismál 33. Fritzner independently gives the same three locations. The normalized verse texts preserve three different grammatical surfaces: goð fjá in Hýmiskviða, mangi fíár in Lokasenna, and Freyr fiásk in Skírnismál. Lexicon Poeticum likewise reports three poetic records, but explicitly warns that its concordance is unreviewed and that dates should be checked. These are source-reported lexical and edited-text records, not directly inspected manuscript objects, and three records in the reviewed poetic concordance are not a census of every Old Norse utterance. The finite verb became a tiny poetic fossil while its inherited participial relative fjándi became the ordinary enemy noun and accumulated 222 citations in ONP's prose corpus. Those corpus totals are not directly frequency-comparable, but the contrast makes the grammatical survival visible. The generated possible runic inscription shown by modern dictionary transcriptions is not historical evidence and is excluded. No historical sound recording exists, so the dossier does not fabricate one exact pronunciation.
