A word appearing in the Early Qenya Grammar of the 1920s as ᴱQ. nellume or neldellume clearly meaning “*three times”, a combination of ᴱQ. nelde “three” and ᴱQ. -llume “times” (PE14/51, 84).

Neo-Quenya: I would retain ᴺQ. nellumë “thrice, three times” for purposes of Neo-Quenya since both elements remain in use in Tolkien’s later writings.
