A word in The Etymologies of the 1930s derived from the root ᴹ√PHI and the basis for the name ᴹQ. Fionwe (Ety/PHI). As described by Christopher Tolkien, the gloss of this word is unclear and might be “haste” or “hawk” (LR/381), but according to Carl Hostetter and Patrick Wynne, the reading “hawk” is more likely.

Though as Christopher Tolkien notes the gloss of Q fion could be read as “haste”, the reading “hawk” appears more likely, especially given the onomatopoeic suitability of the form of the base to the cry of a hawk, and the possible relation of PHI- to PHILIK- “small bird” (EtyAC/PHI).

The word has two plural forms, fioni and fiondi, the latter implying a stem form of fiond-. These probably represent distinct ancient agental formations: ✶-on vs. ✶-ond(o).

A word for “hawk” in the Declension of Nouns from the early 1930s (PE21/8).
