G. crig n. “elbow” (Category: Elbow)
A noun appearing as G. crig “elbow” in the Gnomish Lexicon of the 1910s and related to G. carc “fang” (GL/25, 27) and so probably derived from the early root ᴱ√KṚKṚ from which Qenya “fang” words were derived (QL/48).
Neo-Sindarin: I think it is worth retaining ᴺS. crig “elbow” for purposes of Neo-Sindarin, but reimagined as an elaboration on √RIK “twist” (VT39/7).
