The Elves who refused to journey to Aman, an agental formation of the ancient verb ava-¹ “to refuse” with the common agental suffix -r(o) (VT47/13, WJ/371). This name most frequently appeared in its plural form Avari referring to this entire people (S/52).
Conceptual Development: The name ᴹQ. Avar(o) first appeared in plural form _ in Tolkien’s linguistic notes from the 1930s with the gloss “The Departing”, and referred to those elves who left Middle Earth, whereas those who remained were referred to by the earlier name the ᴹQ. Lembi_ “Lingerers” (LR/169-170). Tolkien soon revised this name to refer to the Elves who remained behind, effectively replacing the term Lembi (LR/200). This name appeared in The Etymologies with essentially the same derivation as given above (Ety/AB).
