There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
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.
