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 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.
