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 glossed “shade, shadow cast by any object” from primitive ᴹ✶daı̯ō under the root ᴹ√DAY “shadow” (Ety/DAY; EtyAC/DAY). This root was primarily used for N. dae “shadow” in N. Dor-Daedeloth “Land of the Shadow of Dread”; in later writings the Dae- element in that name seems to have become dae(r) “great” (WJ/183), so I suspect ᴹ√DAY “shadow” and its derivatives were abandoned.
