The Gnomish Lexicon of the 1910s had G. drui or drû “wood, forest”; Tolkien specified it was not used of wood a material (GL/31). This Gnomish word may be related to the root ᴱ√TUÐU “kindle”; see that entry for details. In Early Noldorin Word-lists it appeared as ᴱN. dron “wood” (PE13/142).
Early Noldorin
turu-
verb. to master
dron
noun. wood
The verb G. tur- “can, have power to” appeared in the Gnomish Lexicon of the 1910s, with two past forms tauri and (more common) turthi (GL/69, 72). It was clearly based on the early root ᴱ√TURU “am strong” (QL/95) as suggested by Christopher Tolkien (LT1A/Meril-i-Turinqi). In notes on names from the 1920s, ᴱN. turu- was gloss “to master” as the basis for the name ᴱN. Turum(b)arth “Lord or Conquerer of Fate” (PE15/61).
Neo-Sindarin: For purposes of Neo-Sindarin, I would use N. orthor- for “to master” and ᴺS. pol- for “to be (physically) able”; see those entries for discussion.
