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.
ehtele
noun. spring, issue of water
kelulinde
noun. spring
kelure
noun. fountain
A noun in the Quenya Verbal System (QVS) from 1948 glossed “fountain”, derived from the verb ᴹQ. kelu- “spring forth (of water)” and a suffix of general action: ᴹQ. -re (PE22/110).
Conceptual Development: A possible precursor is (archaic) ᴱQ. †kektele “fountain” from the Qenya Lexicon of the 1910s, a combination of the roots ᴱ√KEKE “bubble up” and ᴱ√KELE “flow” (QL/46), also mentioned in the Poetic and Mythological Words of Eldarissa (PME/46).
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 “spring” in the Declension of Nouns of the early 1930s, a combination of ᴹQ. kelu- “flow” and ᴹQ. linde “pool” (PE21/10). ᴱQ. kelusindi “river (near its source)” = ᴱQ. kelu- + sindi from the Qenya Lexicon of the 1910s is similar in structure (QL/46).
