A word appearing as ᴱQ. firinga in the Gnomish Lexicon of the 1910s, cognate to G. fring “carcanet, necklace” (GL/59), an element in the early name G. Nauglafring (LT2/221). In notes from this period Tolkien gave the full Qenya translation of this name as ᴱQ. Firin (i) Nautaron along with variants like Naufiringe (PE15/15).
Neo-Quenya: Since we have no better “necklace” words in Tolkien’s later writing, I’d retain ᴺQ. firinga “necklace, carcanet” for purposes of Neo-Quenya.
A noun in the Qenya Lexicon of the 1910s glossed “ray of sun”, derived from the root ᴱ√FIŘI [FIÐI] (QL/38).
