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 verb in The Etymologies of the 1930s glossed “bake” derived from the root ᴹ√MBAS of similar meaning (Ety/MBAS; PE17/51).
Conceptual Development: The Qenya Lexicon of the 1910s instead had ᴱQ. mas- “bake, cook” from the early root ᴱ√M(B)ASA “cook, bake” (QL/59). In that 1910s document it coexisted with ᴱQ. toro- “bake” under the early root ᴱ√TORO (QL/94), but it seems this other root was abandoned. Early Qenya Word-lists had only ᴱQ. mas- with a single gloss “bake” (QL/94). The verb became masta- “bake” in The Etymologies of the 1930s, as noted above.
