The Quenya equivalent of S. Erchamion “One-handed” (VT47/8). It is a compound of er “one” and camba “(cupped) hand”, masculinized by changing the final letter to -o.
Conceptual Development: Tolkien rarely gave a Quenya equivalent for this name, but an early Qenya translation ᴱQ. Elmavoite appeared in the Lost Tales (LT2/34), the cognate of the Gnomish name G. Ermabwed. Its final element is clearly mavoite “having hands” (LT2A/Ermabwed, QL/57), and its initial element is probably er “one” (PE14/47), which according to the Gnomish Lexicon from the 1910s could appear as el- in its prefixal form (GL/32).
In the Early Qenya Grammar from the 1920s, Tolkien wrote erumaite “one handed” (PE14/51, 84; PE16/140), but whether this was a name or simply an ordinary adjective is unclear.
