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 noun in The Etymologies of the 1930s glossed “skin, fell” derived from the root ᴹ√SKEL (Ety/SKEL). It replaced ᴹQ. halma which was derived from the original form of the root {ᴹ√SKAL >>} ᴹ√SKEL (EtyAC/SKEL). Here “fell” is used in its archaic English sense of “an animal’s skin including its hair”, hence “✱hide”.
Conceptual Development: A word ᴱQ. fara “fur, fell” appeared in Early Noldorin Word-lists of the 1920s from primitive ᴱ✶swada, with sw > f as it did in Early Qenya of the 1910s and 20s (PE12/19); in the phonetic developments of later Quenya, sw > hw (PE19/79). Earliest still Tolkien had ᴱQ. vóre “fur” in the Qenya Lexicon of the 1910s under the early root ᴱ√VŌRI of the same meaning (QL/102).
