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 Qenya Lexicon of the 1910s given as ᴱ√KOŘO “revere?” (question mark is Tolkien’s) with derivatives like ᴱQ. korda “temple”, ᴱQ. kordon “idol”, and the holy city of ᴱQ. Kor (QL/48). Many of its Gnomish derivatives began with g-, such as G. gort “idol” and G. gorthin “fane, temple” (GL/41-42), so the true root may have been ✱ᴱ√GOÐO. The city name ᴹQ. Kôr was in later writings derived from ᴹ√KOR “round” (Ety/KOR). However, for purposes of Neo-Eldarin I think it is worthwhile to postulate a root ᴺ√KOD that might be used to salvage the Early Qenya words for “temple” and “idol”, as they were used heavily in Helge Fauskanger’s NQNT (Neo-Quenya New Testament).
