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.

noun. pool
A Doriathrin noun for “pool”, derived from root ᴹ√MBOTH (Ety/MBOTH). Its Quenya cognate ᴹQ. motto suggests a primitive form of ✱✶mbottʰō. As pointed out by Helge Fauskanger (AL-Doriathrin/moth), the primitive [mb-] might be expected to have become [b-], since initial nasals usually vanished before stops in Ilkorin, as for example Ilk. bril < MBIRÍL.
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 noun for “pool” derived from the root ᴹ√LIN (Ety/LIN¹). Its Quenya cognate ᴹQ. linya suggests its primitive form was ✱✶linyā [linjā]. If so, it is an example of how, after [[ilk|final [a] was lost]], the [[ilk|final [j] became [i]]] and then became [e], as suggested by Helge Fauskanger (AL-Ilkorin/line).
