An adjective appearing as G. tauga in the Gnomish Lexicon of the 1910s, based on the verb G. tug- (GL/69) which had among its various meanings the senses “suit, fit, be convenient” (GL/71).

Neo-Sindarin: The verb tug- “suit” is no longer viable in later Sindarin, so I would replace this adjective with ᴺS. cammui “suitable, fitting, convenient” based on the (Neo-Sindarin) verb ᴺS. camma- “to make fit, suit, accommodate, adapt”.
