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.
An adjectival form of ᴹQ. sem(p)- “few” appearing in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/105). Tolkien said it was “chiefly used with genitive”, as in sempa maltō “a small quantity of gold”; likely this refers specifically to its use in the singular form functioning as a nominalized adjective meaning “a small amount, a small quantity”. As an adjective it usually uses a plural: sempar ondoli “some few stones” (PE23/106). Note that in the 1940s, adjective plurals often us -r; in Tolkien’s later system this would probably be ✱sempe ondoli. The adjective may also be used with a singular noun, but this is more emphatic: sempa ondo = “a (very) few stones”, sempa malta = “(very) little gold” (PE23/106).
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. manka “few” under the early root ᴱ√MANGA “lacking” (QL/59).
