Quenya name for the third tribe of Elves (PM/318), usually appearing in the plural form Teleri (S/40; WJ/382). It was derived from the root √TELES “come at rear” (PE18/84; Ety/TELES), because “they tarried on the road and were not wholly of a mind to pass from the dusk to the light of Valinor” (S/53).
Conceptual Development: A similar name ᴱQ. Telelli appeared in the earliest Lost Tales, and its singular form ᴱQ. Telelle was glossed “little elf” in the Qenya Lexicon (QL/91). This early term applied to young Elves of all tribes, especially those talented in song (PE13/99; PE14/9). The related term ᴱQ. Teleri, however, referred specifically to the first tribe of Elves (LT1/50; PE14/9).
By the earliest drafts of the Silmarillion, however, Tolkien began to use ᴹQ. Teler as the term for the “Sea-elves”, the third tribe (SM/13). In The Etymologies from the 1930s, the name was given the derivation above (Ety/TELES), though initially it was because the third tribe “were the latest to awaken” (LR/168), not because they tarried on the march.
