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.
The word for “cheese” in the Gnomish Lexicon of the 1910s was G. cûr, related to G. caura “sour (of milk)” and derived from the early root ᴱ√TYURU “curdle” (GL/26, 28; QL/50). In Gnomish Lexicon Slips added to that document, “cheese” was instead cír from primitive ᴱ√tyus, with an alternate form cur written in pencil above it (PE13/113). In Early Noldorin Word-lists of the 1920s, “cheese” became ᴱN. corn from primitive ᴱ✶kyurna (PE13/140).
Neo-Sindarin: Of these, I prefer ᴺS. cûr for “cheese”, since ᴱN. corn “cheese” collides with later N. corn “round”. I assume ᴺS. cûr is derived from a Neo-Root ᴺ√KYUR “curdle”, perhaps from primitive ✱kyūrŭ.
