ᴹ√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.
