A noun appearing as G. drint “a twist, a wrench, turn” in the Gnomish Lexicon of the 1910s, related to G. drinn “disc” (GL/30). It was thus likely based on a strengthened form of the early root ᴱ√RINI having to do with circles (QL/80).

Neo-Sindarin: Since ᴹ√RIN survived as a root having to do with circles in Tolkien’s later writings, I would retain ᴺS. drint “twist, wrench, turn” for purposes of Neo-Sindarin.
