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 noun in the Gnomish Lexicon of the 1910s appearing as cwim² “body, flesh” underneath G. cwim “awake, alert, alive”, with both apparently being derived from the early root ᴱ√QIV (GL/28); if so the sense “body” probably represent some amount of semantic drift, since the corresponding Qenya forms primarily had the sense “awake” (GL/29). The form cwim² had a variant cwimbri in which the b was deleted, though the editors said it was also possibly that cwimbri >> cwimru.
