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 noun in The Etymologies of the 1930s given as ᴹQ. ringwe “cold pool or lake (in mountains)” derived from the root ᴹ√RINGI “cold” (Ety/RINGI; EtyAC/RINGI). In The Etymologies as published in The Lost Road the form was given as ringe (LR/383), but this was corrected to ringwe by Carl Hostetter and Patrick Wynne in their Addenda and Corrigenda to the Etymologies (VT46/11).
Conceptual Development: ᴱQ. ringwe was glossed “rime, frost” in the Qenya Lexicon of the 1910s under the early root ᴱ√RIŊI (QL/80). In Early Qenya Word-lists of the 1920s, ᴱQ. ringwe was a noun for “cold” (PE16/145).
