verb. to curl (intr.), bend (intr.), wind (twine round anything), twine
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!
A verb glossed {“curl (tr.), braid hair, tie” >>} “curl (intr.), bend (intr.), wind (twine round anything), twine” in the Gnomish Lexicon of the 1910s (GL/54), clearly based on the early root ᴱ√LOKO “twine, twist, curl” (QL/55). Tolkien probably decided this verb was intransitive while introducing G. loctha- “curl (tr.), bend, wind, twine, tie knot, tangle” immediately below it.
Neo-Sindarin: I adapt G. loctha- as ᴺS. loetha- “to curl, bend, wind, twine” to better fit Sindarin phonology, and I would use it both transitively and intransitively, because I prefer to use ᴺS. log- to mean “haul, drag, pull, draw”.
