Middle Primitive Elvish
ur
root. wide, large, great
ur
root. be hot
uruk
root. [unglossed]
yur
root. run
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.
ñgur
root. *death
khor
root. set going, put in motion, urge on
A root in The Etymologies of the 1930s glossed “set going, put in motion, urge on” with various derivatives like ᴹQ. hóre “impulse” and N. hûr “readiness for action, vigour, fiery spirit”, the latter an element in the name Húrin (Ety/KHOR). It is possible this root was later revised to √HOR “urge, impel, move” (VT41/13); see that entry for details.
Neo-Eldarin: For purposes of Neo-Eldarin, I think it is preferable to retain ᴹ√KHOR and its derivatives from the 1930s, since they are fairly distinct in meaning and the later root √HOR presents a number of phonological difficulties, and I prefer its earlier form √GOR.
