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.
mastakorne
noun. [bread] loaf
korne
noun. loaf
kormasta
noun. loaf
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 word appearing as ᴱQ. mastakorne “loaf” in the Qenya Lexicon of the 1910s, a combination of ᴱQ. masta “bread” and ᴱQ. korne “loaf” (QL/59). In Early Qenya Word-lists of the 1920s, “loaf” was instead {korma >>} kormasta (PE16/141).
Neo-Quenya: Since the relevant roots √MBAS “bake” and √KOR “round” continue to appear in Tolkien’s later writings, I would retain ᴺQ. mastacornë “[bread] loaf” for purposes of Neo-Quenya. Compare also [N.] basgorn “loaf” from the 1930s.
