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.
The axe of Tuor, translated “Thudder-sharp”, appearing in various early name lists along with its shorter form Drambor (LT2/203; PE13/103; PE15/22). This name seems to be a combination of drambor “thudder” and leg “sharp”, as suggested by Christopher Tolkien (LT2A/Dramborleg; LT1A/Tári-Laisi). Its Elvish name did not appear in later works (UT/172).
