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 preposition in the Gnomish Lexicon of the 1910s meaning “facing, opposite, over against” (GL/47). In combination with the allative it meant “against, instead of, in return for, for, as”. The derivation of this preposition is unclear, since the early root ᴱ√HATA meant “hurl, fling” (QL/39), and G. hada- “throw at” was grouped with a different set of words (GL/48).
