helma

noun. skin, fell, skin, fell, *hide

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).
