A noun appearing as G. rimp “shred, slice, sliver” in the Gnomish Lexicon of the 1910s (GL/65). It was probably based on the early root ᴱ√RIPI “a rim” from the contemporaneous Qenya Lexicon; compare ᴱQ. ripta- “to cut in strips, tear up” from this same root (QL/80).

Neo-Sindarin: Since I retain the Neo-Root ᴺ√RIP with the sense “strip, stripe”, I would retain ᴺS. rimp “shred, slice, sliver” as well.
