The name that the Teleri used to refer to themselves, usually appearing in the plural form Lindar and glossed “The Singers” (SI/Teleri, UT/286). They were so called because in legend, they sang before they could speak with words (WJ/382). The name was derived from the root √LIN “sing” (SA/lin, WJ/382).
Conceptual Development: In Silmarillion drafts from the 1930s, this name was used for the first tribe, with the gloss “The Fair” (LR/168). It usually appeared as a collective noun, but sometimes appeared in the singular (PE22/51). In The Etymologies, it is given as ᴹQ. linda “fair, beautiful (of sound)” used as a name (Ety/LIND). In later writings, the name of the first tribe became the Vanyar, and Tolkien repurposed this name as another name of the third tribe with a slightly different derivation and meaning.
linda adj. "fair, beautiful" (of sound) (SLIN, LIND; VT45:27), "soft, gentle, light" (PE16:96), "beautiful, sweet, melodious of sound" (PE17:150); for Linda as a noun, see Lindar.
