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”.
A verb appearing as {camba- >>} G. cam(m)a- in the Gnomish Lexicon (GL) of the 1910s with glosses “stoop, bend, bow, cower - submit” (GL/25), probably based on the early root ᴱ√KAẆA “stoop” in the contemporaneous Qenya Lexicon (QL/45). Beneath it was a deleted verb {G. cav-} “to bend”. This deleted verb reappeared later in GL, with the glosses “to bend, make stoop” and its second appearance was also deleted (GL/25). Beneath its second deletion was a verb G. cavra- that Tolkien said was equivalent to camba-; an earlier entry for cavra- was glossed “stoop, cower”, but the glossed entry for cavra- was deleted.
Neo-Sindarin: In Tolkien’s later writings the roots √KAW and √KAM had different meanings, so I don’t think any of these early verbs can be salvaged. I would instead use the neologism ᴺS. logra- “to stoop, bow, cower; to submit” based on the later root √LOK “bend”, a neologism I coined in 2018.
