gwiril
noun. *spindle
cwiril
noun. spindle
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 appearing as G. cwiril “spindle” in the Gnomish Lexicon based on G. cwir- “make spin” (GL/29). Tolkien also gave G. gwiril of the same meaning, apparently based on ᴱ√GWERE “whirl, twirl, twist” (GL/46; QL/103).
Neo-Sindarin: Of these two, I prefer to use ᴺS. gwiril “spindle” because its unmodified form can be based on the later root √WIR “weave”, while cwiril would need to be updated to ᴺS. ✱piril. The form gwiril could be the result of ancient blending of ✱kwiril and ✱wiril.
