ᴱ√FILI root. “fine, thin”
A root in the Qenya Lexicon of the 1910s glossed “fine, thin” and having derivatives like ᴱQ. filwa “fine, thin” and ᴱQ. filqe “fern” (QL/38), the later with a Gnomish counterpart G. fileg “fern” (GL/35). A probable “last gasp” for this root is the word ᴹQ. filet (filek-) “cobweb” from the early 1930s with a deleted gloss “fern” (PE21/33), but there are no signs of this root in Tolkien’s writing after that point.
