An unglossed root appearing in the first version of Tengwesta Qenderinwa from the 1930s (TQ1) to illustrate certain patterns of root formation (PE18/66). It may have serving as the basis for ᴹQ. Maia, though this word was given different derivations later.

pis
root. *juice
This root was one of a surprisingly large number of roots Tolkien used for “juice”, appearing unglossed in The Etymologies of the 1930s with derivatives like ᴹQ. pirya/peich “juice, syrup” and N. pichen “juicy” (Ety/PIS). A similar primitive form ᴱ✶pisye appeared in Early Noldorin Word-lists from the 1920s, with derivatives ᴱQ. pihye/ᴱN. hí “sap, juice” (PE13/147). This in turn might have been a later iteration of unglossed root ᴱ√PḶQḶ from the Qenya Lexicon of the 1910s with a single derivative: ᴱQ. pulqe “juice”.
