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 word appearing as G. bail “sheath, case, cover; pod” in the Gnomish Lexicon of the 1910s, probably based on the early root ᴱ√Baʒ̔- (GL/21). Compare ᴱ√VAẎA “enfold, wind about” from the contemporaneous Qenya Lexicon (GL/21). It was originally translated as “a garment”, but it seems Tolkien transferred that sense to G. baith. ᴱN. bail “sheath” reappeared in Early Noldorin word-lists of the 1920s (PE13/138).
Neo-Sindarin: The later version of ᴱ√VAẎA seems to be ᴹ√WAY “enfold” from The Etymologies of the 1930s (Ety/WAY), so I would adapt this word as ᴺS. gwael “sheath, case, cover; pod” < ✱wailē for purposes of Neo-Sindarin.
