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 word for “sheet” in the Declension of Nouns (DN) from the early 1930s of unclear derivation.
Conceptual Development: In Early Qenya Word-lists of the 1920s, ᴱQ. talat was “dry land” (PE16/139). The word talat also appeared (unglossed) in notes on The Feanorian Alphabet from the mid-to-late 1930s (PE22/20).
