A verb G. drautha- “to weary, tire out” appearing in the Gnomish Lexicon of the 1910s, based directly on the adjective G. drauth “weary, tired” (GL/30). If it were derived from its ancient root, the Gnomish verb would be **draptha-; compare G. naptha- “seize” < ᴱ√NAPA.

Neo-Sindarin: I’d retain this word as ᴺS. drautha- “to weary, tire out” for purposes of Neo-Sindarin based on the Neo-Root ᴺ√(D)RAP.
