Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!

Gnomish

drintha-

verb. to turn (tr.), twist

A verb appearing as G. {drinta- >>} drintha- “to turn (tr.), twist” 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 this verb adapted as ᴺS. drinna- “to turn, twist” to better fit Sindarin phonology.
