ONP classifies fjá as poetic and exposes no prose citations. Cleasby, Fritzner, and Lexicon Poeticum converge on three Eddic contexts, while normalized texts preserve active fjá, finite fíár, and reflexive fiásk. Cleasby then points to fjándi as the participial relative that remained across Germanic. ONP gives that separate enemy noun 222 prose citations and a large semantic range. The two corpus totals are not directly frequency-comparable, and neither proves an exact extinction event; together they reveal the asymmetry between a tiny finite-verb record and the prolific lexicalized enemy branch.
