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.

Qenya 

pirya

noun. juice, syrup, juice, syrup, *sap

A noun in The Etymologies of the late 1930s glossed “juice, syrup” derived from the root ᴹ√PIS (Ety/PIS).

Conceptual Development: Several earlier words seem to be precursors of this one. The Qenya Lexicon of the 1910s had ᴱQ. pulqe “juice” under the early root ᴱ√PḶQḶ which was unglossed and had no other derivatives (QL/74). Early Noldorin Word-lists of the 1920s had ᴱQ. pihye, a cognate of ᴱN. hí “sap, juice” and derived from ᴱ✶pisye (PE13/147). The Declension of Nouns from the early 1930s had ᴹQ. pite “juice” pl. pitsin (PE21/7).

Neo-Quenya: For purposes of Neo-Quenya, I would use this word for thicker juices, syrups and ✱sap, as opposed to ᴹQ. sáva as “juice” for drinking (such as from fruits).

apsa

noun. juice

pite

noun. juice

sáva

noun. juice

A noun in The Etymologies of the late 1930s glossed “juice” from the root ᴹ√SAB of the same meaning (Ety/SAB).

Conceptual Development: ᴱQ. văsă “juice” from the Gnomish Lexicon of the 1910s (a cognate to G. gwâs) is a possible precursor (GL/44).
