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.
Quenya
andúril
proper name. Flame of the West
The name of Aragorn’s sword after it was reforged (LotR/277), rechristened from its original name Narsil. This new name is a combination of the prefix andú- “west” and the root √RIL “brilliance” (PE17/35, 47). It was translated “Flame of the West” (LotR/277, Let/425).
Conceptual Development: Aragorn’s sword was long called Branding in Lord of the Rings drafts, and ᴹQ. Andúril did not appear until a late typescript (WR/370).
