There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
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).
