A root in The Etymologies of the 1930s glossed “run” with derivatives like ON. yur- “run” and N. iôr “course” (Ety/YUR). It was a later iteration of ᴱ√ẎURU “run” from the Qenya Lexicon of the 1910s with derivatives like ᴱQ. yuro “a run, race” and ᴱQ. yuru- “run” (QL/106). For purposes of Neo-Eldarin, it is probably better to stick to the better attested root √NOR.

An unglossed root in The Etymologies of the 1930s with the derivatives ᴹQ. norsa/N. noroth “giant”; the root was initially written as ᴹ√NOROT or ᴹ√NOROS (Ety/NOROTH; EtyAC/NOROTH). This root probably replaced the deleted entry {ᴹ√KHANKA >>} ᴹ√KHAN-AK “giant” > ᴹQ. hanako, also from The Etymologies (EtyAC/KHAN-AK). This in turn may have displaced the earliest derivation for “giant” words: ᴱ✶naχū́a > ᴱQ. nauva from The Qenya Phonology of the 1910s (PE12/10).
