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.
