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 appearing as G. socthor “a drinking-horn” in the Gnomish Lexicon of the 1910s, a combination of G. sog- “drink” and G. târ “horn” (GL/68). It appeared below a variant G. sogli with the abstract noun suffix -li and above another variant sogridâr with both an abstract noun suffix and târ “horn”.
Neo-Sindarin: Since √SOK “drink” and [N.] sog- reappeared in Tolkien’s later writings, I would retain this noun but adapt it as ᴺS. soethor “drinking-horn” to reflect the later Sindarin *okt* > *oith* > *oeth*. I would further assume the second element was derived from ᴹ√TARAK “horn (of animals)” (Ety/TARÁK), perhaps -tārak > -taura > -thor where the final *k* vanished as it often did in longer words.
