A noun appearing in 1967 notes on the Nomenclature of the Lord of the Rings as an element in Finglas “Leaflock” (RC/760). The form fineg appeared unglossed in notes from around 1965 as a derivative of ✶phinik (PE17/17). The word fing is more obscure than S. find of similar meaning.
Conceptual Development: The word G. fingl or finnil “a tress” appeared in the Gnomish Lexicon of the 1910s (GL/35). In that period, the gl was probably the result of the sound change whereby ðl became gl, since this early form was likely derived from the root ᴱ√FIŘI [FIÐI] (QL/38). When it first appeared, the name N. Finglas (= find + las?) may also have had a similar sound change, but since Tolkien abandoned that phonetic rule in Sindarin of the 1950s and 60s (compare S. edlenn vs. N. eglenn “exiled”), Tolkien needed to come up with a new etymology.
